That enginer is a perfect example of what good vehicle maintenance does over the life of your vehicle. Those bearings were still smooth. Minimal piston wear, good rings, etc..etc..etc.. This TH-cam channel is great. I love it.
its been scientifically proven engines last longer when they run and drive at operating temperature and not go through many cold starts and warming up periods. this is why semi-trucks can last over a million miles.
@@ericmartin2470 Semi trucks also run at much lower RPMs, have thicker cylinder walls, larger bearings, stronger connecting rods, produce less power per liter of displacement, are usually made from stronger alloys, hold significantly more oil. Apples to oranges
As a retired lube oil engineer with Chevron, this video stresses the importance of maintenance and regular oil change intervals. Not sure what brand of oil this gentlemen used but it was clearly a top tier product. Really enjoyed this video and glad I found your channel.
@@earskinpresley5264AMSOIL is the best.I’ve been using it for 25 years 15-40 in my 2001 Duramax LB7 . It still has the original Injectors in it .I use Amsoil Diesel injector cleaner every fillup since the Truck was new.
@@turtlekoff1 I used Mobil 1 Delvac 15w40 ESP Turbo Diesel oil for the first 750k the balance was Lorenzo’s oil from a company called Insane Diesel, same company I got the bypass oil filter from.
In the late '90's, using parts I rounded up on Jegs/Summit, I built a pre-start oil pressuring system. I used a small tank, connected through the oil pressure sensor, wired to my ignition. Before I started it, by turning the key on, it brought the oil pressure up to about 5 psi and then I started it.
Very interesting. My first new car was a 1999 Mercedes E300 with 796,000 miles, the OM606 Diesel. The engine and transmission has never been out of the car. It has been running on Mobile 1 synthetic 10W-30. It still runs well. Currently we are replacing the fuel pump because the original one developed a crack and started leaking oil. The goal is to crack a million miles.
I grew up in my dad's shop which was a Mercedes indy shop and the best thing you can do on for that engine is swap you filter halfway through the oil change interval. if you read the old Mercedes maintenance manual it even recommends it. The m103/m104/om606 blocks are one of the best engine blocks ever made. I got rid of my w202 after 350k just because of all the other aging car issue that I did not want to deal with it anymore for a daily driver but the guy I sold it to still drives it at 450k miles.
The 1999 E300 has a system that tells you when to change the oil. Since this car runs on the highway, the oil change interval is right around 20,000. Over this time, the engine has consistently used 3 quarts of oil during this time, unless an oil leak develops. It gets driven nearly 240 miles to work, then a few days later home. It has always been idled a couple minutes before driving unless it is very cold then a few minutes longer.
@@user-oi8tg3dq7tthose Mercedes engines are indestructible. I had a friend who's mother wore out the car and, after setting in the weeds for a couple years, he pulled it and put it in a big 20k forklift. That was 20 years ago and it's still running, though it does burn oil now
I don't know. My grandfather had about 3 diesel Benz and they all were garbage. My brother gave him a old Chevy Impala and he told us the Chevy was the best car he ever owned. He said he wasted all that time playing around with Mercedes 😅
My dad's friend invented an auxiliary oil filter and my dad allowed him to put one on my 1982 Rabbit diesel. I drove that car for 496,357 miles. The only part of the engine that was ever opened was the oil pan to plumb in a return line, and the valve cover to replace the leaking gasket. Sold the car to a diesel parts shop as a parts runner. The filter added 4 quarts to the system and changed the oil every 10k.
Interesting video. I got a 07 Ram 3500 with 6.7 Cummins with 979231 miles on original engine. Engine never opened up and maintained well with a bypass oil filter using good oils and filtermag on oil filter. Bypass oil filter was only used about the last 1/3 of its mileage. Engine works like new with more power then i need no kidding. Best truck i ever owned Praise GOD!!
My 1972 240Z Datsun had 660,535 miles on it, when we finally scrapped it in 2002. Was used as a family car, and multiple long trips. As a GM engineer, I was able to maintain it and keep it running. However at some point, common parts were no longer available for cheap, so there came a crossover, where a newer car was needed. We also had a 1975 Toyota Camry, which we finally gave away to Goodwill in 2005. It lasted another year, then the new owner trashed it because she ran it out of oil. We saw it along the road, abandoned, looked into the hood, and saw the obvious. It made me cry. Our regular family car, 1995 Honda Accord has 275K on it, and still going strong. I ran an estimate, and these cars have saved us over 2+million dollars, over buying a new car every year.
Nobody buys a new car every year. Stop embellishing and exaggerating. If you bought a brand new f150 every 10 years it would only cost you $150k over 30 years. And that’s if you don’t sell the 10 year old one for anything but realistically a 10 year old f150 still going for 20-25k.
Being an engineer, you were more likely to have mechanical sympathy, and address issues like servicing and checking and changing your oil regularly. I have seen engines where the funny red light which sometimes illuminated, turned out to be the oil light, and needed 4.5 litres to top up. That is just asking for misery. I have also seen a car which was so hot to the touch, that I needed rags to approach the bonnet. Inside the engine bay, the exhaust headers were glowing red-orange. Turned out to be zero coolant and oil. She said, I just need to get to an appointment, and drove off.
Don't forget that $pec oil every 5k, all the additives, driving it "daily", the DPF clean out(s) and two shakes of a voodoos stick every morning. Miss one and it's YOUR FAULT the pump blew up, etc., etc. Diesel dudes be funny.
Wrong... evidence proves if an engine runs and drives at operating temperature with less cold starts and warming up periods the engine will last much longer. this is why semi-trucks can last over a million miles. you herd the owner say "I haul campers".
@@ericmartin2470people that use trucks personally always have now failures than commercially used trucks in my experience. Unless it's a Dodge/Ram they struggle to last no matter what here in NY.
I think as far as diesel engines go, operating under load is better for them than just daily driving. Pulling trailers around is keeping the engine running clean along with good maintenance. Same in Class 8 trucks, too. This driver understands his equipment.
I have over 400K on my 2007 Ram 2500 (5.9 Cummins). Most of those miles were on the highway, pulling a trailer. It's retired from long haul driving now, and carefully maintained for occasional hauling. I'm likewise retired, so my daily drivers don't get more than 1500 or 2000 miles per year. It will be my last ever truck purchase, and is practically a family member.

Hello Dave's Auto Center. I think the lifters you want for your awesome engine builds are the eeze roll lifters by isky cams which use a bushing with oil lubrication groove design. They were commonly used by big daddy don garlitz on top fuel engines, I saw them on the engine build parts lists at don garlitz museum. Hope it helps
The hate spewing over a 900k mile engine that literally needed a cam and lifters to be good again is absolutely ridiculous. Say what you want about the "flawed" oiling system, it apparently works just damn fine.
I think it’s more of pointing out ways it could be improved. And he mentioned he’s seen many fail at lower mileages. Some people don’t hate, has nothing to do with emotion, other than passion to improve things, maybe every engine would last 900k with that kind of… “hate.” 🤘
Dave, you guys should’ve gone over the bypass oil filter setup in-depth and told viewers what the brand was and such. Maybe that’d be a great idea for another video on this truck/engine. It’s obviously a great product, and everyone in the comments is curious about them after watching this. I know you don’t make em, but it’d still be cool to shoutout a good product and tell us all about it. I guarantee you’re gonna have people interested in them after seeing inside that engine, so I hope you either start sellin em or tell people where to get em.
@ because this is America and I can watch and have an opinion about anything that I choose. I also have the freedom to type and share my opinions on public platforms.
@@paulbennett274Awesome, I see it now. I couldn’t find it when the video came out so idk if it was there before or I’m just blind lol. I hope Dave does an in-depth video on the system in a video cause it’s obviously something that works and I’d like to hear more about it and how it looks mounted in the truck and everything.
I have ran the FS2500 oil filter for 650,000 miles on a Cummins 5.9 24 valve. I have no issues with the motor except a few oil leaks. I still drive the truck daily.
I brought my engine to a shop to get rebuilt. They where annoyed it still had the oil pan on and intake. I don't get it. Just charge me more to take it off and give me an option to charge me more to put it on. Why get all pissy. You are in it to make money. You have the tools and knowledge to do it, why not just happily take my money and not be a little b*tch about it. Also I dont have a parts cleaner to clean my oil pan and intake, so I need your equipment to do that. That being said I like the videos and thanks for the videos
In Dave's case, he's generally dealing with other businesses, which are fully capable of stripping the block. Like he said, this engine was shipped by a mechanic. They should should know better. I knew the differences between short and long blocks, and complete engines before I was 10 years old. Shipping it full of oil was the icing on the oil cake. I understand your position, but businesses rightly determine what their needs are. They could have been more gracious about it for sure, but at base, you and that business were a bad match, and you should have used a more suitable one. As a locksmith, I've been asked to do things that were illegal, unethical, or just outside what was sensible and profitable for me to do. You think you should tell someone to "just" do what YOU want them to do. Sorry, but no. Get real. Call someone else. Period
Ya i didn't see what the fuss was about. You call yourself an engine rebuild shop so take the oil pan and the valve covers off and charge accordingly. Wtf's the big deal ?
This engine use case is interesting because the guy obviously did regular maintenance, plus he benefitted from very long duty cycles driving campers across the country (the opposite of stop and go). In addition, he also had that 1 micron filter they mentioned at the beginning of the video. HOWEVER, he did also say in an earlier video that he did idle the truck all the time. Remember he said he would regularly sleep in the truck on long trips and idle the truck overnight, contrary to what Dave said at the 16:15 mark. To me this says that excessive idling in a vacumm is indeed bad BUT if you are doing regular maintenance and running the truck for long periods at peak (non-idle) engine temps, you can still prevent a lot of engine wear and carbon build up. Thoughts?
its been scientifically proven engines last longer when the oil is at operating temperatures and not having to go through a warming up period with frequent cold starts like you see in a passenger car. if auto manufactures implemented oil heating to 160 degrees followed by pre-oiling before engine start then we would see engines lasting much longer. but who would go through a 20+ min sequence before starting?
@@ericmartin2470 Heating the oil also heats components, which reduces wear on start up’s . The cold and hot cycles are extremely hard on engines. A cold engine on start up has less clearance between components. Pre-oiling would be beneficial. Could we get people to plug their gas or diesel engines in to maintain temp?
Better efficiency but yeah less reliability from needle bearings. And i.m.o. bronze bushing thats can impregnate with oil will always be better long term than a roller
Generally when calculating life time of bearings there is a 10% failure rate used. Reason is that there are so many parts with individual tolerances. So you check the lifetime but accept failure. Benefits are less friction - after 900k mls this is no failure, it is just wear due to concept.
I love your channel Dave. Although I now work as an engineer, in the field of biomechanics, machines have always been my love. Sometimes that's why I stop by my old workshop and visit the old team and the new owner who was my young worker 20 years ago. We look together at what is on the table and what goes into processing, and we almost always end the discussion on the fact that today there are not so many bad engines, as there are many bad owners. Dave, I congratulate you on a job well done as always (although I know there are days in our lives when it would be best if we stayed in bed that morning) and I wish your team and you much luck and success. P.S. there is no going back now, stay good as you are.
A long time ago now, I drove commercial charter motor coach out of Ohio. Our owner had about 120 coaches. Some were 6V92 and some were Detroit 60 series. (Yes, I am old). We all knew that those engines could easily go 1.5 million or more. But they were swapped at 500k. PM and passenger safety was first on the list.
@@dsstaang new semi-trucks needs to meet EPA regulations put in place during Obama. this has had a detrimental effect on diesel engine longevity. the reason you'd see 2.5 million miles is because those truck engines spent the vast amount of time running at operating temperatures and not having to go through cold starts and warming up periods. the motor oil needs to be above 160 degrees to lubricate properly.
As my late Dad always said "oil is cheap, engine parts are expensive". I change every 3k synthetic and often on my 2001 f150 supercrew it's 1000 because a yr has passed 😉 but yes oil and filters ..
FYI: The oil was drained, it’s in the gray bucket on the ground behind Dave. Any oil that’s coming out now is what has settled in the oil pan since it was pulled out in October. Also , this engine is packaged as a core that has to be sent back to ford as what they consider a long block. In the summer of 2023 the ford dealer in Wyoming had to reseal the upper, lower oil pans, and the front and rear cover. Spring of 2024 the upper oil pan was leaking again, come to find out when the repair was done the first time the tech inadvertently stripped the bolt hole in the rear cover which caused the new leak. So the job had to be repeated with the addition of a new rear cover.
The secret behind all these high mileage cars, vans, trucks. Frequent oil change, forget what the manufacturer's say, change the oil and filter every 3'000 miles. The other thing that helps is not too many cold starts, this guy ran his truck for 12 hours a day, so most of the mileage was done on a warm engine and warm oil. Any engineer will tell you, most of the wear on an engine is done in the minutes after start up of a cold engine. Treat her gently until you have her up to running temperature.
As a gear head since I was a kid I was always told that if you do proper services on diesels you should get a million miles out of them and there’s your proof. What a great video !! First time seeing a diesel motor hit those miles with a tear down and showing that if you do the oil changes and do the proper precautions of taking care of a diesel motor that’s the out come. Love your videos Dave. You have a great crew as well. Take notes people !!!
You can use a ball bearing with a flat micrometer to measure a bearing's thickness, just accurately measure the ball bearing first, then subtract that from your measurement.
@TucsonDude a ball bearing is perfectly round, what are you talking about? Plus you measure the ball bearing then take that measurement into account when taking your final measurements.
My old '01 F250 7.3 I bought new and sold to my friend in '05 is still on the original engine at 760k miles. He runs it hard, but he's meticulous with maintenance and runs Amsoil diesel fuel additive in every tank. Modern diesel fuel is garbage. Probably the best thing you can do for a diesel engine is add some lubricity to the fuel and keep the filters changed.
I twisted my Dad's arm to start adding a bit of power service every other fill-up on his 1997 7.3 and he hasn't stopped bragging about better mileage and running super smooth. You're right ..we have crap diesel anymore, these poor engines need extra lubricity.
You can thank Al Gore for “dry” diesel fuel. He had the petroleum industry take out the surplus that lubricants the fuel. The supposedly low emissions regulations. Total and BS technology.
Clint , of Custom Works, a 7.3 YT channel, already showed the data specs which filters are best on our diesels. The AMSOIL “by pass” filter on their dual filter set up, is Unsurpassed, other filters can use , Donaldson BD7405, Baldwin B7039, Total purple filter, Amsoil EA099, Mobil1. on & on. You’re Welcome.
All Fram filters are trash! Will never use a Fram. Had 1 that had a pinhole in the side, and engine lost oil pressure, it was a chevy 6.0 , thankfully the low oil pressure light came on n I stopped in time
Keep some of the rod bearings in an exhibition for customers and tell them the mileage with regular oil changings. Put failed/scratched/worn out bearings of a low-mileage engine with bad maintenance besides them as a SHOCKER.
Ain't no body gonna talk about the Toilet paper oil filter his friend built that the owner used from the first month he bought his truck? To get it almost 900K miles.
I use a filter by Gulf Coast that uses a roll of heavy duty paper towels. Works great. I drain and replace six quarts of oil from the filter and change the filter every 5-10 k miles. Oil analysis always says the crankcase oil is good to run. I usually change all 20 quarts of oil the bypass and full flow filters every 30 k or so. 25 years and going strong. 2000 7.3
Dave, nettle bearings spread the load more than a bushing will, think about it you can't have a dedicated oil supply so the impact would be on just two areas of th4 lifter. The needles move around so the load isn't iin the same area every stroke. The total area covered would be less than the needles. I think they designed the lifters the best way, not the only way, but the best for a push rod engine. The best way would be with overhead cams. Push rods are for lawn mowers.
This isn’t totally true. Bushings apply the load to the film of oil. Needle bearing apply the load to the needles. There is a reason pistons and main bearings are bushings and not needle. If flowing oil is available bushings are better. If flowing oil isn’t available (such as a drive shaft yoke) needle bearings are better.
I'm impressed . Almost 900,000 MI and those main bearings look perfect well I guess what really says that you really need to put a better oil system in and what the guy put in better stuff to keep your oil clean and your temperature is down and if it had better lifters that would be a million mile engine wow thank you Dave for putting such good videos out about diesels I had a 6.2 Ford on 85 f250 and I thought I maintained the engine really good I got 400,000 miles before I got rid of it I always put a bigger oil filter on and I had a dual rancor fuel filter system and I always added additives to my fuel and that engine always ran great it finally started to I had a head gasket go out and about $410,000 MI so I had to get rid of it but it was my favorite truck
I usually only idled when it was very cold or very warm, total engine hours(running and idling) 24,610 which is 19.2% idle time. Higher than I would like but necessary!
So true about the needle bearing lifters. My engine builder put bushed roller lifters in my 420 Dart Windsor drag engine that ran low 10s all day long with a mild tune.
Probably Synthetic Rotella 15w40. Probably changed every 5000 miles. But considering the advanced filtering system, and road traveling without stop and go, might he have gone to 10k but I doubt it. Very impressive life out of a motor especially considering how hard he worked it. I would probably guess 5000 mile changes.
@@phil4986In the first video with the owner and Dave’s son Miles the truck owner said he did oil analysis routinely and based on how well the oil did he started with 5000 mile changes, then 7500 and I believe he ended up going at least 10,000. But it seems the key is that the truck ran 12 hrs a day every day towing travel trailers from coast to coast. The engine was always at full operating temperature with clean oil and fuel. I have an acquaintance who also towed travel trailers with his Ram 3 liter Ecodiesel and got 462,000 miles on the first engine and over 300,000 on the second before he moved up to a Cummins. Modern diesels need to be run, little idling and longer trips. City driving and modern emissions don’t go together. Look at Dave’s video before this one “Looking at CP4 at 900,000 miles.”
Was that truck deleted, I’m sure it idled a ton being that was his home but taking epa out of the equation resulted in that truck going that long with his stellar maintenance to help!
I didn't hear Dave ask the guy about idle time, but he said he spent 12 hours a day in his truck, so I'd like to hear from him about his idle time. Everyone wants to know about the brand of oil, but I'm more interested in the filter. Subaru developed an oil filter that I used to use called a Trasko. It's a canister filter and you replace the element. The element resembles a roll of toilet paper, but it wasn't. It also had a super fine stainless screen that would capture metal flakes. The first oil change on my Fed Ex Ground Workhorse P30 had about five flakes of metal in it; I about filled my shorts. I added Lucas at my monthly oil changes and never saw another flake. I sold the the truck at over 300k miles and never had an issue with the motor.
I have marine engines. I centrifuge my oil every 50-100 hours. The centrifuge returns oil to semi transparent, almost as clear as new. Because the engines are free of sludge, the oil never gets completely black. I test the oil once or twice a year. Before I started using a centrifuge I used a bypass filter. I get 2 or 3 times the service life between overhauls than others using the same engines in the same service. The biggest difference is in the sleeve and ring wear. But my bearings also look like new. Crankshafts don't wear. I haven't ground a crank since the 1960s. Clean oil makes a huge difference. I also drain my PU and run the oil thru the centrifuge. I like having people check my oil for their expression when the dipstick has transparent oil. I'm anxious to use speed of air pistons.
@@MIKEmofit There's always going to be wear, but the cross hatching lasts 2-3 time longer and is usually the deciding factor for overhaul. Mostly 2 cycle, so I can see the piston and sleeve thru the ports.
Always great advice from the expert who knows engines. This is a great example of how proper care and maintenance affect a diesel engine. Thanks for making this video. It is an inspiration for those who care about their engine. Don’t idle unnecessarily and change the oil and filters with good quality products at frequent intervals! Simple!
love these tear down/build videos. Would love to see an upcoming video on different oil brands/viscosity comparison between the top brands I've run AMSOIL 5w40 signature series full synthetic since bought brand new in my 2015 ford 6.7 going on 350k strong!
As I recall, this guy was doing 10k-15k mile oil changes with a bypass and oil analysis. Is Dave’s motors going to require him to change oil at 3k as it states on their website for warranty? Dave is marveling at how clean the engine is, and at the same time telling people to cut their service interval in half. This thing was going almost double the recommended oil change interval and it’s spotless. But the guy was doing it the right way. My hang up is Dave require proof of 3,000 mile oil changes for warranty. This is proof that this policy is out dated and not friendly to the customer.
@ you aren’t wrong but that has nothing to do with the oil. It saved his CP4 pump for sure. But the bearings and pistons look awesome for an engine 1/4 the miles. His oil change interval was perfectly appropriate at more than 10,000 mile intervals. Is Dave going to honor his engine warranty at this interval or is he going to stick to the 3,000 miles as stated on their warranty page? That’s the question
@@mebordernoneya8484 The owner was always doing very long trips delivering stuff (he did say but I can't remember what he delivers). That in itself means that the engine was always running at highway speeds and under load. Any carbon build up under those conditions would be extremely small. Even if he did sleep with the engine idling (as he said he did) when he is back on the road again any carbon deposited from idling would be burned off in no time.
@ Dave’s engines sells long blocks. Emissions has nothing to do with a long block other than being built with the right compression ratio, quench, and valve recession. Emissions all happen on equipment bolted to the long block.
@@Vikturus22 fun thing is that depending on your location and dimension for distance measuring the „barrier“ is different - million mls or million km. 🤣 With around 1.5 mio km and these clean journal bearings - really impressive.
Great video. So safe to say. Upgrade your lifters. Definitely an over time wear part. Crazy to think just a few little parts over time and use. A few little things fail and bam! Engine failure. Upgrade valve train parts and possibly clear 1 million miles with ease.
coming from a ford tech, that is how ford sends most (LONG BLOCKS), pan, front cover, rear adapter, etc. some of those parts on certain engines are integral to the assembly, oil pick-ups and such. what you sell is closer to a short block with heads. I would put money on it that is deleted as well.
Exactly what I was thinking plus those parts protect the inners from damage and moisture... Dave's being so picky on certain things it could bring more issues.
Actually, it probably doesn't have anything deleted as this guy has to have a DOT inspection every year in order to haul campers. Running all highway miles with a good diesel additive keeps the DPF in the best shape that a DPF can be in.
@salsuginusrex5196 you obviously don't know how things work, for example in CT where I live if your registered 10001 lbs you're exempt from emissions, if you think these guys are not exploiting every lope hole you are a fool
I’ve used Insane Diesels products on all my vehicles for years. It’s an investment for sure but it pays for itself in a year with maintenance cost and fuel economy.
@@meganbaum515 from the videos I watched on insane diesels social media, it looks like the guy used most of insane diesels products. Like fuel additive, oil and the bypass filter.
In the first video the owner said he tested his oil the first 2 or 3 changes, then put his changes out at 15,000 miles, and even testing that oil showed it was good enough to leave it in. But he changed every 15,000 anyway. That auxiliary filter must have worked great !
Back in the day when I used to build two-stroke dirt bike motors, the lower rod bearing, and it was a needle bearing, it would always fail, & the needles would get sucked through the ports, and it would always end up chewing up the top of the piston. It would always happen on the real high horsepower KX80, CR 250, last one I did was an RM250. They would press the crank halves together, in the rod was a solid piece with needle bearing between the crank journal. I can't tell you how many cases I split to change the rod bearing in a 2-stroke dirt bike....
If you add his total engine idle hours of 4,714 and times it by 30 = 141,420 miles and you add his odometer mileage of 892,315 = 1,033,735 total miles on his engine.
or even delay in ignition/fuel injection, you crank engine 20x and after that, startup. with decompression system cranking would be 2x faster than normal and startup would be easier.
it would be better if the engine had a pre-heater and heat the oil to operating temperature before starting. a pre-oiler would do nothing because engine oil needs to be hot before it starts working properly. Dave got this wrong as does most people.
Amzoil with a bypass filter. 325k on my Mazda pickup. Changed oil 5 times. Engine was clean as a whistle and ran like a top! Got tired of driving it. Sold it after 14 yrs and 325K.
From my own experiences with needle roller bearings, I have always considered them to be superior to plain bearings. In my two-stroke motorbike engines, both brands, Yamaha and Suzuki, the top end bearings were needle roller equipped, and never failed me, Both engines didn't use pre-mix, but rather a metered oil supply via the carburettors. I have had more trouble with big end roller bearings, strangely enough, though I know why, in that single instance. I do appreciate your argument in this case, where the bearing surface receives minimal oil feed at start up, on each occasion.
Doesnt marter. Most ouls nowadays are the same Some have a few kore additives. The b8ggest th8ng is oul changes intervals! These new 8ntervals are dumb!
I have a 2010 Kia Sportage 2.7 liter . Just turned 652,000 klms last week . Super tech 5W30 full sythetic Fram oil filter and oil changes at 10,000 klm intervals . Timing belt every 100,000 klms . Still running strong and don't have to add between changes .
Totally agree with your forensic analysis Dave, the surface bearing pressure of a thin line compared to a rectangle is probably one to two orders of magnitude lower - probably10 to 100 times lower, if bushes were installed from new, the engine would last probably +2M miles 😊
The needle bearings experience a point load. Theoretically the surface area of the bearing on the race is zero square inches. That changes of course on the quality of manufacture, the wear on the bearing, and the tolerances. It is like a locomotive wheel. It is solid steel in a "perfect" circle, resting an a steel rail that is perfectly flat. What is the contact area....Zero square inches in theory.
"Theoretically" the contact between pin and bushing is also zero. The difference with a larger diameter pin in pin/bushing vs needle is more area is closer with the pin, more area for oil to suspend the pin. Catch-22 is the pin/bushing must have oil else contact is made. Needle bearing can roll with less wear during low oil conditions.
Ball bearings are even worse, especially if sizes aren't perfect, because then a lot of heat will concentrate on the largest bearings and then guess what? My experience is based on the front left on a Mazda MX5 race car where I ended up replacing them as a maintenance item every 6 months, thus getting rid of the failures.
The Carbon in the Ring Pack is a sign of PCV System function. If that system fails the Ring Pack will be overloaded with carbon and it all goes downhill from there. Few if anyone acknowledges or tests this system other than loosening the Filler Cap to see if it has a slight vacuum holding it down at Idle. It's as simple as hooking a Manometer to the dipstick tube at Hot/Idle. All engines should have 500K+ of service life with little to no problems, gas or diesel. Great video guys.
I wonder how many times those injectors fired. Those bearings proved how important oil changes & filtration are. I would have NEVER thought bearings with that many miles on them could look that good. Think how many times that crankshaft rotated with all that pressure on it. Amazing.
Exactly. Bushings were made because race engines the open spring load can be 1000 lbs. The bushing will last longer with the heavy load. A bushing will not last 900k unless possible it has direct oil pressure.many millions in engineering has gone into longevity engineering. I think the roller bearing lifter with oil changer is just fine. Change yur oil.
I once had a BMW motorcycle. The rockers had needle bearings, and at about 50K miles, it started to rattle pretty bad. The rockers were Very easy to get to, so I pulled the covers, and the needles on one of the rockers were destroyed. I tried to get parts, and Wow, were they Spendy! Cheep old me, I had access to a lathe, and some babbitt stock. I was a complete beginner, and there was no YT in the seventies, so I just winged it. I milled down the babbitts and ported the shaftway with oil holes for lubrication. I pressed the babbitts into the rockers, and drove it another 150K. Never needed another adjustment. A truck took it out.
Like to know all modifications the owner did to cooling, fuel filtration, and lubrication (both oil brand and filtration) to keep this engine going for so long.
I have always serviced my older cars myself, Because I could, The newer cars ive owned are a bit too complicated so ive always got them done by the dealer (Ford) But ive always done them on time and I have always got a good life out of them with no major problems👍
so nobody remembers POWERSTROKE HELP shop truck (7.3) ? broke a rod abusing with NO2 , but at 800,000 miles the crosshash , bearings, lifters.... all amazing condition....
Running that oil by-pass filter on his truck definitely improved his engine longevity. I'm currently running the Amsoil by-pass filter on my 6.7l Cummins company truck to hopefully keep my truck down time to a minamum.
@@Drewdayz2419 Amsoil are 2 micron filters, the ones this guy used (insane diesel) are 1 micron. I used to run the Amsoil in a diesel myself, but found myself changing the element every 5k or less, as it plugged up and quit filtering, as evident in the lack of return flow. The insane diesel elements are much larger and get 3x the mileage or more while filtering finer. YMMV
I'm currently eyeing a garage kept '92 Mercedes Benz 500 SEL with 305,xxx on the odo and its cleaner than the Board of Health. The second owner who's had it for the last 15 yrs got it from the original and they both kept it maintained with every service record stored in a 3 ring binder since new. Although the MB is a gas motor, this vid has really given me inspiration on motor longevity with care and maintenance. Hmmm, not mention, this video pushes me closer to purchasing that beauty🤔
That enginer is a perfect example of what good vehicle maintenance does over the life of your vehicle. Those bearings were still smooth. Minimal piston wear, good rings, etc..etc..etc.. This TH-cam channel is great. I love it.
That is one well designed engine. Those bearing surfaces are amazing.
its been scientifically proven engines last longer when they run and drive at operating temperature and not go through many cold starts and warming up periods. this is why semi-trucks can last over a million miles.
Yeah. The thermal cycling kills them. Also, the engine spends less time at operating temp.@ericmartin2470
@@ericmartin2470 Semi trucks also run at much lower RPMs, have thicker cylinder walls, larger bearings, stronger connecting rods, produce less power per liter of displacement, are usually made from stronger alloys, hold significantly more oil. Apples to oranges

As a retired lube oil engineer with Chevron, this video stresses the importance of maintenance and regular oil change intervals. Not sure what brand of oil this gentlemen used but it was clearly a top tier product. Really enjoyed this video and glad I found your channel.

Thanks for sharing your expertise and for watching! 👍
@@turtlekoff1 I used Mobil 1 Delvac 15w40 ESP Turbo Diesel oil for the first 750k the balance was Lorenzo’s oil from a company called Insane Diesel, same company I got the bypass oil filter from.
In the late '90's, using parts I rounded up on Jegs/Summit, I built a pre-start oil pressuring system. I used a small tank, connected through the oil pressure sensor, wired to my ignition. Before I started it, by turning the key on, it brought the oil pressure up to about 5 psi and then I started it.
I remember kits like this for sale in the 1990’s.
You wasted your time congrats
@@nanerpussz why wasted time?
I've thought about building a pre-lubrication system.

They should have an auxillary oiling system with all these start/stop engines.
Very interesting. My first new car was a 1999 Mercedes E300 with 796,000 miles, the OM606 Diesel. The engine and transmission has never been out of the car. It has been running on Mobile 1 synthetic 10W-30. It still runs well. Currently we are replacing the fuel pump because the original one developed a crack and started leaking oil. The goal is to crack a million miles.
I grew up in my dad's shop which was a Mercedes indy shop and the best thing you can do on for that engine is swap you filter halfway through the oil change interval. if you read the old Mercedes maintenance manual it even recommends it. The m103/m104/om606 blocks are one of the best engine blocks ever made. I got rid of my w202 after 350k just because of all the other aging car issue that I did not want to deal with it anymore for a daily driver but the guy I sold it to still drives it at 450k miles.
The 1999 E300 has a system that tells you when to change the oil. Since this car runs on the highway, the oil change interval is right around 20,000. Over this time, the engine has consistently used 3 quarts of oil during this time, unless an oil leak develops. It gets driven nearly 240 miles to work, then a few days later home. It has always been idled a couple minutes before driving unless it is very cold then a few minutes longer.
@@user-oi8tg3dq7tthose Mercedes engines are indestructible. I had a friend who's mother wore out the car and, after setting in the weeds for a couple years, he pulled it and put it in a big 20k forklift. That was 20 years ago and it's still running, though it does burn oil now

Diesel Pump UK your to go channel
My dad's friend invented an auxiliary oil filter and my dad allowed him to put one on my 1982 Rabbit diesel. I drove that car for 496,357 miles. The only part of the engine that was ever opened was the oil pan to plumb in a return line, and the valve cover to replace the leaking gasket. Sold the car to a diesel parts shop as a parts runner. The filter added 4 quarts to the system and changed the oil every 10k.
Interesting video.
I got a 07 Ram 3500 with 6.7 Cummins with 979231 miles on original engine.

My 1972 240Z Datsun had 660,535 miles on it, when we finally scrapped it in 2002. Was used as a family car, and multiple long trips. As a GM engineer, I was able to maintain it and keep it running. However at some point, common parts were no longer available for cheap, so there came a crossover, where a newer car was needed. We also had a 1975 Toyota Camry, which we finally gave away to Goodwill in 2005. It lasted another year, then the new owner trashed it because she ran it out of oil. We saw it along the road, abandoned, looked into the hood, and saw the obvious. It made me cry. Our regular family car, 1995 Honda Accord has 275K on it, and still going strong. I ran an estimate, and these cars have saved us over 2+million dollars, over buying a new car every year.
Who buys a new car every year bro?
How buys a car every year for life?
Nobody buys a new car every year. Stop embellishing and exaggerating. If you bought a brand new f150 every 10 years it would only cost you $150k over 30 years. And that’s if you don’t sell the 10 year old one for anything but realistically a 10 year old f150 still going for 20-25k.
The first year they made the camry was 1983...
Being an engineer, you were more likely to have mechanical sympathy, and address issues like servicing and checking and changing your oil regularly. I have seen engines where the funny red light which sometimes illuminated, turned out to be the oil light, and needed 4.5 litres to top up. That is just asking for misery. I have also seen a car which was so hot to the touch, that I needed rags to approach the bonnet. Inside the engine bay, the exhaust headers were glowing red-orange. Turned out to be zero coolant and oil. She said, I just need to get to an appointment, and drove off.
Couldn't help smiling in disbelief at not seeing any copper peaking through the bearing.
Great system and taken care of too.

I think as far as diesel engines go, operating under load is better for them than just daily driving. Pulling trailers around is keeping the engine running clean along with good maintenance. Same in Class 8 trucks, too. This driver understands his equipment.
I have over 400K on my 2007 Ram 2500 (5.9 Cummins). Most of those miles were on the highway, pulling a trailer. It's retired from long haul driving now, and carefully maintained for occasional hauling. I'm likewise retired, so my daily drivers don't get more than 1500 or 2000 miles per year.

Hello Dave's Auto Center. I think the lifters you want for your awesome engine builds are the eeze roll lifters by isky cams which use a bushing with oil lubrication groove design. They were commonly used by big daddy don garlitz on top fuel engines, I saw them on the engine build parts lists at don garlitz museum. Hope it helps
$1500 each wow! 🤯
@@philipmilsom9544 Actually that price is for one set of 16 lifters
The hate spewing over a 900k mile engine that literally needed a cam and lifters to be good again is absolutely ridiculous. Say what you want about the "flawed" oiling system, it apparently works just damn fine.
It's all snake oil salesman nonsense to get people worried and to buy their "fix".
I think it’s more of pointing out ways it could be improved. And he mentioned he’s seen many fail at lower mileages. Some people don’t hate, has nothing to do with emotion, other than passion to improve things, maybe every engine would last 900k with that kind of… “hate.” 🤘
but if it didn't have a "flawed" oil system, it might have gone 990k mi....
Some people are happiest when they're miserable.

Dave, you guys should’ve gone over the bypass oil filter setup in-depth and told viewers what the brand was and such. Maybe that’d be a great idea for another video on this truck/engine. It’s obviously a great product, and everyone in the comments is curious about them after watching this. I know you don’t make em, but it’d still be cool to shoutout a good product and tell us all about it.

In Dave's case, he's generally dealing with other businesses, which are fully capable of stripping the block. Like he said, this engine was shipped by a mechanic. They should should know better. I knew the differences between short and long blocks, and complete engines before I was 10 years old. Shipping it full of oil was the icing on the oil cake. I understand your position, but businesses rightly determine what their needs are. They could have been more gracious about it for sure, but at base, you and that business were a bad match, and you should have used a more suitable one. As a locksmith, I've been asked to do things that were illegal, unethical, or just outside what was sensible and profitable for me to do. You think you should tell someone to "just" do what YOU want them to do. Sorry, but no. Get real. Call someone else. Period
@@robertmoffett3486I hope you go out of business soon with that horrible attitude.
Ya i didn't see what the fuss was about. You call yourself an engine rebuild shop so take the oil pan and the valve covers off and charge accordingly. Wtf's the big deal ?
They want any leaks to be someone else's problem maybe.....I'd be delighted with not having responsibility for leaks or silicone in oil strainer😂
This engine use case is interesting because the guy obviously did regular maintenance, plus he benefitted from very long duty cycles driving campers across the country (the opposite of stop and go). In addition, he also had that 1 micron filter they mentioned at the beginning of the video. HOWEVER, he did also say in an earlier video that he did idle the truck all the time. Remember he said he would regularly sleep in the truck on long trips and idle the truck overnight, contrary to what Dave said at the 16:15 mark.
To me this says that excessive idling in a vacumm is indeed bad BUT if you are doing regular maintenance and running the truck for long periods at peak (non-idle) engine temps, you can still prevent a lot of engine wear and carbon build up. Thoughts?
Agreed.
perhaps a egr delete and a more advance oil filtration system.
I wonder what brand oil he used?
its been scientifically proven engines last longer when the oil is at operating temperatures and not having to go through a warming up period with frequent cold starts like you see in a passenger car. if auto manufactures implemented oil heating to 160 degrees followed by pre-oiling before engine start then we would see engines lasting much longer. but who would go through a 20+ min sequence before starting?
@@ericmartin2470 Heating the oil also heats components, which reduces wear on start up’s . The cold and hot cycles are extremely hard on engines. A cold engine on start up has less clearance between components. Pre-oiling would be beneficial. Could we get people to plug their gas or diesel engines in to maintain temp?
As a sewing machine mechanic, I replaced needle bearings with a bushing made by the manufacturer. Way too many failures with needle bearings.
Better efficiency but yeah less reliability from needle bearings. And i.m.o. bronze bushing thats can impregnate with oil will always be better long term than a roller
Generally when calculating life time of bearings there is a 10% failure rate used. Reason is that there are so many parts with individual tolerances. So you check the lifetime but accept failure.
Benefits are less friction - after 900k mls this is no failure, it is just wear due to concept.
Imagine telling a guy your needle bearings are bad....😆
I never realized sewing machine mechanics existed lol
@@Peterswarahedwhat's so funny about that ?

I love your channel Dave. Although I now work as an engineer, in the field of biomechanics, machines have always been my love. Sometimes that's why I stop by my old workshop and visit the old team and the new owner who was my young worker 20 years ago. We look together at what is on the table and what goes into processing, and we almost always end the discussion on the fact that today there are not so many bad engines, as there are many bad owners.
Dave, I congratulate you on a job well done as always (although I know there are days in our lives when it would be best if we stayed in bed that morning) and I wish your team and you much luck and success.
P.S. there is no going back now, stay good as you are.
A long time ago now, I drove commercial charter motor coach out of Ohio. Our owner had about 120 coaches. Some were 6V92 and some were Detroit 60 series. (Yes, I am old). We all knew that those engines could easily go 1.5 million or more. But they were swapped at 500k. PM and passenger safety was first on the list.
I worked at Penske we had 100 Detroit diesels
Daylily put all the other motors to shame not great on horsepower or fuel economy but they were very reliable
not to forget the best sounding diesels
@@dsstaang new semi-trucks needs to meet EPA regulations put in place during Obama. this has had a detrimental effect on diesel engine longevity. the reason you'd see 2.5 million miles is because those truck engines spent the vast amount of time running at operating temperatures and not having to go through cold starts and warming up periods. the motor oil needs to be above 160 degrees to lubricate properly.
As my late Dad always said "oil is cheap, engine parts are expensive". I change every 3k synthetic and often on my 2001 f150 supercrew it's 1000 because a yr has passed 😉 but yes oil and filters ..
FYI: The oil was drained, it’s in the gray bucket on the ground behind Dave. Any oil that’s coming out now is what has settled in the oil pan since it was pulled out in October. Also , this engine is packaged as a core that has to be sent back to ford as what they consider a long block. In the summer of 2023 the ford dealer in Wyoming had to reseal the upper, lower oil pans, and the front and rear cover. Spring of 2024 the upper oil pan was leaking again, come to find out when the repair was done the first time the tech inadvertently stripped the bolt hole in the rear cover which caused the new leak. So the job had to be repeated with the addition of a new rear cover.
If your the owner what you use for the disel
@ could you be a little more specific please?
Out of curiosity what is your oil change frequency and what oil are you using?
What brand of oil and fuel additive did you use?
No one wants to know if it was deleted? Are you running any fuel additives??
The secret behind all these high mileage cars, vans, trucks.
Frequent oil change, forget what the manufacturer's say, change the oil and filter every 3'000 miles.
The other thing that helps is not too many cold starts, this guy ran his truck for 12 hours a day, so most of the mileage was done on a warm engine and warm oil.
Any engineer will tell you, most of the wear on an engine is done in the minutes after start up of a cold engine. Treat her gently until you have her up to running temperature.
I guess the only problem with this statement is thatI the owner of this truck performed oil changes every 10-15,000 miles based on oil analysis.
So very true. Even bad engines can survive much longer, if they get some love and sympathetic attention.
A good quality engine doesn't need that. You just should know before buying what is good quality.
As a gear head since I was a kid I was always told that if you do proper services on diesels you should get a million miles out of them and there’s your proof. What a great video !!

My old '01 F250 7.3 I bought new and sold to my friend in '05 is still on the original engine at 760k miles. He runs it hard, but he's meticulous with maintenance and runs Amsoil diesel fuel additive in every tank. Modern diesel fuel is garbage. Probably the best thing you can do for a diesel engine is add some lubricity to the fuel and keep the filters changed.
I twisted my Dad's arm to start adding a bit of power service every other fill-up on his 1997 7.3 and he hasn't stopped bragging about better mileage and running super smooth. You're right ..we have crap diesel anymore, these poor engines need extra lubricity.
The bypass filter, fuel enhancement and oil this guy used is made by INSANE DIESEL
back in the day up in LA, many diesel truck owners I knew used ATF in each tank of diesel, cleaned and lubed at the same time.
You can thank Al Gore for “dry” diesel fuel. He had the petroleum industry take out the surplus that lubricants the fuel. The supposedly low emissions regulations. Total and BS technology.
What I have heard, is that American Diesel fuel is run without any sulphur? That is a way to damage the engine and limit its life expectancy.

@@hanseich You ever seen a Frantz filter? If anything they vastly improved it.

All Fram filters are trash! Will never use a Fram. Had 1 that had a pinhole in the side, and engine lost oil pressure, it was a chevy 6.0 , thankfully the low oil pressure light came on n I stopped in time
Keep some of the rod bearings in an exhibition for customers and tell them the mileage with regular oil changings.
Put failed/scratched/worn out bearings of a low-mileage engine with bad maintenance besides them as a SHOCKER.
Could only imagine what Bill Hewitt would say, that’s amazing how long that went as well as it did.
Ain't no body gonna talk about the Toilet paper oil filter his friend built that the owner used from the first month he bought his truck? To get it almost 900K miles.
Dude! That’s what I’m saying. The latter part of the video should have been showcasing that system so the people can find it.
A company called a “Frantz” makes that style oil filter, and they actually sell a cartridge that isn’t off-the-shelf TP though you can still do that.
I use a filter by Gulf Coast that uses a roll of heavy duty paper towels. Works great. I drain and replace six quarts of oil from the filter and change the filter every 5-10 k miles.
Oil analysis always says the crankcase oil is good to run.
I usually change all 20 quarts of oil the bypass and full flow filters every 30 k or so. 25 years and going strong. 2000 7.3
Dave, nettle bearings spread the load more than a bushing will, think about it you can't have a dedicated oil supply so the impact would be on just two areas of th4 lifter. The needles move around so the load isn't iin the same area every stroke. The total area covered would be less than the needles. I think they designed the lifters the best way, not the only way, but the best for a push rod engine. The best way would be with overhead cams. Push rods are for lawn mowers.
came to the comments to say this about needles vs bushings.
This isn’t totally true. Bushings apply the load to the film of oil. Needle bearing apply the load to the needles. There is a reason pistons and main bearings are bushings and not needle. If flowing oil is available bushings are better. If flowing oil isn’t available (such as a drive shaft yoke) needle bearings are better.
I'm impressed . Almost 900,000 MI and those main bearings look perfect well I guess what really says that you really need to put a better oil system in and what the guy put in better stuff to keep your oil clean and your temperature is down and if it had better lifters that would be a million mile engine wow thank you Dave for putting such good videos out about diesels I had a 6.2 Ford on 85 f250 and I thought I maintained the engine really good I got 400,000 miles before I got rid of it I always put a bigger oil filter on and I had a dual rancor fuel filter system and I always added additives to my fuel and that engine always ran great it finally started to I had a head gasket go out and about $410,000 MI so I had to get rid of it but it was my favorite truck
I usually only idled when it was very cold or very warm, total engine hours(running and idling) 24,610 which is 19.2% idle time. Higher than I would like but necessary!
As I understand it, Iskenderian Cams has bushed roller lifters, I do not know who makes it for them, but it is something to look at.
So true about the needle bearing lifters. My engine builder put bushed roller lifters in my 420 Dart Windsor drag engine that ran low 10s all day long with a mild tune.
I love how Dave is with his employees. He is awesome. I’m glad he bitches here and there but for the most part it seems like they love them.
"oh man thanks for coming thats pretty neat that your engine lasted this long" then proceeds to bash the same dude for not shipping it correctly lmao
He also didn’t realize that he was going to be installing it, if it gets rebuilt!
It would be interesting to know what oil was used and how often it was changed?
Probably Synthetic Rotella 15w40. Probably changed every 5000 miles. But considering the advanced filtering system, and road traveling without stop and go, might he have gone to 10k but I doubt it. Very impressive life out of a motor especially considering how hard he worked it. I would probably guess 5000 mile changes.
@@phil4986In the first video with the owner and Dave’s son Miles the truck owner said he did oil analysis routinely and based on how well the oil did he started with 5000 mile changes, then 7500 and I believe he ended up going at least 10,000. But it seems the key is that the truck ran 12 hrs a day every day towing travel trailers from coast to coast. The engine was always at full operating temperature with clean oil and fuel. I have an acquaintance who also towed travel trailers with his Ram 3 liter Ecodiesel and got 462,000 miles on the first engine and over 300,000 on the second before he moved up to a Cummins.

@@chrisforte8229and what did he use
Super impressed. Very well designed engine and the benefits of regular maintenance. That is a lot of miles.
Was that truck deleted, I’m sure it idled a ton being that was his home but taking epa out of the equation resulted in that truck going that long with his stellar maintenance to help!
I’d bet it wasn’t. They can check for emissions stuff in some states, because the hot shot drivers are considered commercial.
I didn't hear Dave ask the guy about idle time, but he said he spent 12 hours a day in his truck, so I'd like to hear from him about his idle time.
Everyone wants to know about the brand of oil, but I'm more interested in the filter.
Subaru developed an oil filter that I used to use called a Trasko. It's a canister filter and you replace the element. The element resembles a roll of toilet paper, but it wasn't. It also had a super fine stainless screen that would capture metal flakes. The first oil change on my Fed Ex Ground Workhorse P30 had about five flakes of metal in it; I about filled my shorts. I added Lucas at my monthly oil changes and never saw another flake. I sold the the truck at over 300k miles and never had an issue with the motor.
@@cameronvanmeter2626 saw a photo of the hours on the dash and there was over 4000 hours idle time and just under 20000 total hours
Only motor I have ever seen in person was a 7.3 powerstroke I watched it roll over on the mileage odometer. Crazy for a 6.7 this is amazing
I have marine engines. I centrifuge my oil every 50-100 hours. The centrifuge returns oil to semi transparent, almost as clear as new. Because the engines are free of sludge, the oil never gets completely black. I test the oil once or twice a year. Before I started using a centrifuge I used a bypass filter. I get 2 or 3 times the service life between overhauls than others using the same engines in the same service. The biggest difference is in the sleeve and ring wear. But my bearings also look like new. Crankshafts don't wear. I haven't ground a crank since the 1960s. Clean oil makes a huge difference. I also drain my PU and run the oil thru the centrifuge. I like having people check my oil for their expression when the dipstick has transparent oil.
I'm anxious to use speed of air pistons.
SO YOU STILL HAVE CROSS HATCH IN THEM BORES THEN LIKE THE DAY THAY WAS HONED . NO WHEAR AT ALL .
@@MIKEmofit There's always going to be wear, but the cross hatching lasts 2-3 time longer and is usually the deciding factor for overhaul. Mostly 2 cycle, so I can see the piston and sleeve thru the ports.
Always great advice from the expert who knows engines. This is a great example of how proper care and maintenance affect a diesel engine. Thanks for making this video. It is an inspiration for those who care about their engine. Don’t idle unnecessarily and change the oil and filters with good quality products at frequent intervals! Simple!
I would be curious if this truck had the factory emissions equipment on it... Also, what oil filtering system did he have on it?
love these tear down/build videos. Would love to see an upcoming video on different oil brands/viscosity comparison between the top brands I've run AMSOIL 5w40 signature series full synthetic since bought brand new in my 2015 ford 6.7 going on 350k strong!
As I recall, this guy was doing 10k-15k mile oil changes with a bypass and oil analysis. Is Dave’s motors going to require him to change oil at 3k as it states on their website for warranty?
Dave is marveling at how clean the engine is, and at the same time telling people to cut their service interval in half. This thing was going almost double the recommended oil change interval and it’s spotless. But the guy was doing it the right way.
My hang up is Dave require proof of 3,000 mile oil changes for warranty. This is proof that this policy is out dated and not friendly to the customer.
Most people don't use additives like this owner did.
@ you aren’t wrong but that has nothing to do with the oil. It saved his CP4 pump for sure. But the bearings and pistons look awesome for an engine 1/4 the miles. His oil change interval was perfectly appropriate at more than 10,000 mile intervals. Is Dave going to honor his engine warranty at this interval or is he going to stick to the 3,000 miles as stated on their warranty page? That’s the question
@@mebordernoneya8484
The owner was always doing very long trips delivering stuff (he did say but I can't remember what he delivers). That in itself means that the engine was always running at highway speeds and under load. Any carbon build up under those conditions would be extremely small. Even if he did sleep with the engine idling (as he said he did) when he is back on the road again any carbon deposited from idling would be burned off in no time.
Dave’s engines are also emissions compliant you can’t tell me that engine was pushing through an EGR
@ Dave’s engines sells long blocks. Emissions has nothing to do with a long block other than being built with the right compression ratio, quench, and valve recession. Emissions all happen on equipment bolted to the long block.
one of thee best channels on youtube!!! every "lay person" should watch these ☺️👌
Shows us that the weakest link will fail the entire engine. But with this mileage I would call it an overall success! 🎉
892k miles on og engine. Passed reliability check. I’m fine with an engine failure at this mileage.
@@Vikturus22 fun thing is that depending on your location and dimension for distance measuring the „barrier“ is different - million mls or million km. 🤣
With around 1.5 mio km and these clean journal bearings - really impressive.
Great video. So safe to say. Upgrade your lifters. Definitely an over time wear part.
Crazy to think just a few little parts over time and use. A few little things fail and bam! Engine failure. Upgrade valve train parts and possibly clear 1 million miles with ease.
coming from a ford tech, that is how ford sends most (LONG BLOCKS), pan, front cover, rear adapter, etc. some of those parts on certain engines are integral to the assembly, oil pick-ups and such. what you sell is closer to a short block with heads. I would put money on it that is deleted as well.
Exactly what I was thinking plus those parts protect the inners from damage and moisture... Dave's being so picky on certain things it could bring more issues.
It definitely has an EGR still; Dave refers to it when talking about the low amount of carbon trash on the piston head.
Actually, it probably doesn't have anything deleted as this guy has to have a DOT inspection every year in order to haul campers. Running all highway miles with a good diesel additive keeps the DPF in the best shape that a DPF can be in.
Yes, I'd like to hear the answer from the owner.
@salsuginusrex5196 you obviously don't know how things work, for example in CT where I live if your registered 10001 lbs you're exempt from emissions, if you think these guys are not exploiting every lope hole you are a fool
I’ve used Insane Diesels products on all my vehicles for years. It’s an investment for sure but it pays for itself in a year with maintenance cost and fuel economy.
Nice! It looks like this bypass filter is the best system currently out there !
@@eyezb4645 I wish I had this product on my truck when I bought it. Just ordered one !
did they use insane diesels oil in this engine ?
@@meganbaum515 from the videos I watched on insane diesels social media, it looks like the guy used most of insane diesels products. Like fuel additive, oil and the bypass filter.
@@eyezb4645 I’ve used amsoil bypass filter and my oil wasn’t even close to as clean using insane diesel. So I’d say so
Just wanted to let you guys know love your videos Dave you da man buddy
What brand of oil and how often changed is my question?
Synthetic Often, that's the best brand
Red Line full synthetic 15W-40. Has group V Ester base oil and a ton of additives
In the first video the owner said he tested his oil the first 2 or 3 changes, then put his changes out at 15,000 miles, and even testing that oil showed it was good enough to leave it in. But he changed every 15,000 anyway. That auxiliary filter must have worked great !
Back in the day when I used to build two-stroke dirt bike motors, the lower rod bearing, and it was a needle bearing, it would always fail, & the needles would get sucked through the ports, and it would always end up chewing up the top of the piston. It would always happen on the real high horsepower KX80, CR 250, last one I did was an RM250. They would press the crank halves together, in the rod was a solid piece with needle bearing between the crank journal. I can't tell you how many cases I split to change the rod bearing in a 2-stroke dirt bike....
6:20 “We don’t talk about that” 😮😅
Great video! Really appreciate the thoroughness of you and your team.
Needle bearings must be reasonably durable. Almost 900k out of it.
Nice to see how you explain this engine problems!😊
If you add his total engine idle hours of 4,714 and times it by 30 = 141,420 miles and you add his odometer mileage of 892,315 = 1,033,735 total miles on his engine.
Except idling isn’t mileage.
@@MudOilnGearsExactly, often it is worse!
@@MudOilnGearsit’s not, but….its worse on the engine then running. I was told!
What was the total engine hours?
@@twostroker56 19896 running hours, 4714 idle hours, total hours 24,610.
I don’t know anything about engines but that was fascinating and well explained sir 🇬🇧
Imagine if that engine had a startup pre-oiler.
or even delay in ignition/fuel injection, you crank engine 20x and after that, startup. with decompression system cranking would be 2x faster than normal and startup would be easier.
it would have made it beyond 1 million mile mark
it would be better if the engine had a pre-heater and heat the oil to operating temperature before starting. a pre-oiler would do nothing because engine oil needs to be hot before it starts working properly. Dave got this wrong as does most people.
Amzoil with a bypass filter.
325k on my Mazda pickup.
Changed oil 5 times.
Engine was clean as a whistle and ran like a top!
Got tired of driving it.
Sold it after 14 yrs and 325K.
You mean to tell me that you changed oil 5 times in 325k miles? Are you stupid?
The bots just love learning about diesel engine tear downs.
Yea....you gotta respect em for their willingness to learn outside of their wheelhouse.!
I guess they got tired of learning about aliens from Joe Rogan.
Crazy amount of revolutions that engine and minimal amount of wear awesome video I admire this man’s knowledge about engines 👍✌️❤️
What is your take on Valvoline Restore oil and where can you get it? 🤔
there is a great video on that oil if you havent seen it already , the motor oil geek reviewed it.
First time I seen this guy, great video! Definitely checking out the rest. Well done!
How did the rear main seal do with that many miles?
From my own experiences with needle roller bearings, I have always considered them to be superior to plain bearings. In my two-stroke motorbike engines, both brands, Yamaha and Suzuki, the top end bearings were needle roller equipped, and never failed me, Both engines didn't use pre-mix, but rather a metered oil supply via the carburettors. I have had more trouble with big end roller bearings, strangely enough, though I know why, in that single instance. I do appreciate your argument in this case, where the bearing surface receives minimal oil feed at start up, on each occasion.
I wonder what brand oil was used during it's life and the oil change interval.
Doesnt marter. Most ouls nowadays are the same
Some have a few kore additives. The b8ggest th8ng is oul changes intervals! These new 8ntervals are dumb!
I really enjoyed that.
Thank You Dave!
Woo-hoo! 900k!
Screwed Harley engines when they switched from bushing cams to needle bearings! Nice vid,
What are top 5 best oiling systems by engine? Is it true LS oiling systems are a weakness?
I have a 2010 Kia Sportage 2.7 liter . Just turned 652,000 klms last week . Super tech 5W30 full sythetic Fram oil filter and oil changes at 10,000 klm intervals . Timing belt every 100,000 klms . Still running strong and don't have to add between changes .
love your videos dave
Totally agree with your forensic analysis Dave, the surface bearing pressure of a thin line compared to a rectangle is probably one to two orders of magnitude lower - probably10 to 100 times lower, if bushes were installed from new, the engine would last probably +2M miles 😊
The needle bearings experience a point load.
Theoretically the surface area of the bearing on the race is zero square inches. That changes of course on the quality of manufacture, the wear on the bearing, and the tolerances.
It is like a locomotive wheel. It is solid steel in a "perfect" circle, resting an a steel rail that is perfectly flat. What is the contact area....Zero square inches in theory.
"Theoretically" the contact between pin and bushing is also zero. The difference with a larger diameter pin in pin/bushing vs needle is more area is closer with the pin, more area for oil to suspend the pin. Catch-22 is the pin/bushing must have oil else contact is made. Needle bearing can roll with less wear during low oil conditions.
Ball bearings are even worse, especially if sizes aren't perfect, because then a lot of heat will concentrate on the largest bearings and then guess what? My experience is based on the front left on a Mazda MX5 race car where I ended up replacing them as a maintenance item every 6 months, thus getting rid of the failures.
The Carbon in the Ring Pack is a sign of PCV System function. If that system fails the Ring Pack will be overloaded with carbon and it all goes downhill from there. Few if anyone acknowledges or tests this system other than loosening the Filler Cap to see if it has a slight vacuum holding it down at Idle. It's as simple as hooking a Manometer to the dipstick tube at Hot/Idle.
All engines should have 500K+ of service life with little to no problems, gas or diesel. Great video guys.
I wonder how many times those injectors fired. Those bearings proved how important oil changes & filtration are. I would have NEVER thought bearings with that many miles on them could look that good. Think how many times that crankshaft rotated with all that pressure on it. Amazing.
that's proof that journal bearings work without any wear if everything is ok.
Keeping the oil clean, not necessarily changes. Bypass filter or centrifuging. Oil analysis will prove this out.
You know the reason for that, lubrication! The owner used good oil and short intervals. Plus he added on another oil filter.
11:03 If I was the guy operating the truck I think I would go with this advice.
Replace the lifters around 750,000
And if it does not make it to 750k then what. ??
@hankclingingsmith8707 Then I guess it was an anomaly or the guys lying about how many trouble free miles he actually had on that engine.
Truly your best video!
If the needle bearings where a bad design then alot more would have failed with 900,000 miles on it. Not sure if I buy into this theory
Exactly. Bushings were made because race engines the open spring load can be 1000 lbs. The bushing will last longer with the heavy load. A bushing will not last 900k unless possible it has direct oil pressure.many millions in engineering has gone into longevity engineering. I think the roller bearing lifter with oil changer is just fine. Change yur oil.
I once had a BMW motorcycle. The rockers had needle bearings, and at about 50K miles, it started to
rattle pretty bad. The rockers were Very easy to get to, so I pulled the covers, and the needles on one of the rockers were destroyed.
I tried to get parts, and Wow, were they Spendy! Cheep old me, I had access to a lathe, and some babbitt stock.
I was a complete beginner, and there was no YT in the seventies, so I just winged it. I milled down the babbitts
and ported the shaftway with oil holes for lubrication. I pressed the babbitts into the rockers, and drove it
another 150K. Never needed another adjustment. A truck took it out.
Like to know all modifications the owner did to cooling, fuel filtration, and lubrication (both oil brand and filtration) to keep this engine going for so long.
I have always serviced my older cars myself, Because I could, The newer cars ive owned are a bit too complicated so ive always got them done by the dealer (Ford) But ive always done them on time and I have always got a good life out of them with no major problems👍
so nobody remembers POWERSTROKE HELP shop truck (7.3) ? broke a rod abusing with NO2 , but at 800,000 miles the crosshash , bearings, lifters.... all amazing condition....
Dave you're right on the song, it does have " I'll be watching you" in the song.
The roller lifter concept must make the engine better on fuel…
Amazing overview. Love seeing the longevity , promising when you take care if you vehicle
Running that oil by-pass filter on his truck definitely improved his engine longevity. I'm currently running the Amsoil by-pass filter on my 6.7l Cummins company truck to hopefully keep my truck down time to a minamum.
That’s the best one on the market I think
@@Drewdayz2419 Amsoil are 2 micron filters, the ones this guy used (insane diesel) are 1 micron. I used to run the Amsoil in a diesel myself, but found myself changing the element every 5k or less, as it plugged up and quit filtering, as evident in the lack of return flow. The insane diesel elements are much larger and get 3x the mileage or more while filtering finer. YMMV
I'm currently eyeing a garage kept '92 Mercedes Benz 500 SEL with 305,xxx on the odo and its cleaner than the Board of Health. The second owner who's had it for the last 15 yrs got it from the original and they both kept it maintained with every service record stored in a 3 ring binder since new. Although the MB is a gas motor, this vid has really given me inspiration on motor longevity with care and maintenance.
Hmmm, not mention, this video pushes me closer to purchasing that beauty🤔
Would love to know how many injectors he went through
And what issues he had throughout its life
One set and a turbo. Watch the cp4 teardown and he goes on about the repairs
Watching is the correct wordage..
