I spent a formidable part of my life as a heavy duty mechanic. A side bar to this video is, a broken truck is not a deal breaker but a price adjuster. I prefer to buy trucks that require some sort of repairs prior to being usable. I’ve bought my truck with blown bearings in the bull gear. A relatively simple repair. But a lot of guys figure dump the truck.
One other thing to look for is correct fastener use...are all the bolts holding down the part the same? Most engines don't hold down a part with different kinds/styles of fasteners. Its a red flag for a shoddy repair and that repair ethos probably follows through to other repairs & maintenance.
bought used 1997 e350 7.3. heavy gray smoke. esp when cold. i changed oil& filter every 69 days for 2 years. 2 years later it runs like a demon and no smoke. still change oil every 10 k miles. its got over 495 k miles and no problems and wil out pull every truck on the road up to 12/25/18
With my first truck, I bought it from my friend’s nephew. With being inexperienced I went with his word, which, worked out for me. The problems I have had with it was unforeseen, but, that c12 is a workhorse and I love CAT. Fast forward to today. Going to a dealer to look at my next truck and you have been a godsend to me. Going to do this to weed out the ones I am serious about, then, have a diesel mechanic set up to do an inspection on it. Thanks again for making this a little less stressful.
You need to do a video about equipment auction sabotages ,,,I know this is a trick(this is where you're at the auction and all the equipment is idleing people are checking them ou)this trick is from an old horse trader this is for older diesel equipment ,,,auctions every diesel engine at idle between the 200 300 RPM range (harmonic resonance)) you could find a point where you're idling it for that motor just knocks like hell once a idle Pointe was found he would set that equipment at that point if he wanted to buy it,,,, and other machines if didn't want to buy it he could find an idle Point with that motor sounded like a sewing machine,,,,,,, then every time somebody played with the idle on his prospective new machine he'd run back there and set that Idol making it knocked like hell,,,,, so when you're buying a quipment at all actions there's so many different ways people sabotage equipment I machine could have been idling for hours fine ,, so when time the auctioneer comes around they can't get it started ,,,, then after it's been sold The Saboteur un sabotage & it starts it up and drives his new machine to his stable,,,,,,, do a video on all the s*** people can do at all actions and how to spot it,,,,,, I'm an old diesel dog from lay back but I enjoyed your video and learned a few things new,,,, when you quit learning in life that means your dead lol
Saw it done many times. Older districts almost always had an emergency air flap mounted above the super charger.It was activated with either a cable or electric solenoid. You could trip it by hand and make it look like it wasn't done. No air getting in to burn the fuel. Cummins might have a emergency fuel stop. Activated the same was. I have seen somebody turn the fuel off or almost off, then loosen the nut on arm and reset it look open. Put tape on the terminal and on of the fuel solenoid so it doesn't open.
Just bought a 2000 Freightliner......1.3 million, in wonderful condition, has Destroit 12.7 in it that runs but it's getting on towards that time..... To build a scary motor, tee hee! I learn so much basic shit from your videos, and I've been doing this for almost fifty years, that I'd like to thank you.
Great job. That video will be very helpful for a lot of people! Been a me panic for over 45 years.disel, BY and propane, hybrid drive and electric, auto trans rebuild,etc. You a Great mechanic, hope you continue liking being one and continue giving out your knowledge.
Good vid.. One thing I find is really good to listen to is the exhaust and the intake, listen for any cylinder that doesn't fire the same as the others, a rhythmic "ump" in the exhaust, or listening on the intake side maybe a rhythmic hiss of a leaking intake valve Always like watching a 'dep'dape vid
Most all used equipment will need some type of service . It's about looking for signs of abuse and OD roll backs . He covered quite a bit in this video .
I'am new here, Mr.Ape you have a very good show. I'am hard of hearing due to operating Locomotives the last couple decades, I can clearly hear you without issue. Thanks for sharing your knowledge with us. ✌️ Thank you Mr.Ape 👍
Wish I would've had this video a year ago. Bought a old Schneider truck that had coolant in oil but didn't know what to look for. Lasted little over a week b4 it died. This video will save a lot of people
I bought a tractor, bloke said it didn't smoke, when i got it home i knew what i was in for as it had been sitting for 10 years in a paddock, well did it smoke? it blew more smoke than a steam train, the fix for blow by was put a piece of rag on the dipstick, the oil filter had never been changed in its life, i didn't need to change the oil as it used it like fuel, when it finally let go i found out the farmer used an angle grinder to clean up the weld on the cracked block between the cylinder bore, i had to get another block and i rebuilt the engine, also i had to take the radiator apart as it was blocked solid by dirt, now runs perfect.
Josh I really dig your vids. I really do. BUT> Lets be honest. DPF is a bad joke on the working Man. This is the reason why I will not allow my Sons to buy a Kenworth with a accert engine. First reason 18:1.... You have to be kidding me? 18:1 plus twin turbos that spool up at 50 psi with lift a head. Second reason CO2 is plant food. How does all of these hippies think the oil got in the ground to begin with? Look I could go on and on.... I think your a very smart wrench. Keep up the good work.
There's only two reasons to get a used engine. One is to get that famous torque from 1100 to 1400 RPM that's only available on yellow engines. In which case, everything you mentioned applies. The other reason for a used engine... Revenge! A twin turbo 8v92 with straight pipes, mated to a 5 and a 4, is perfect for running passed the neighbor's house at 4 in the morning, after having been kept up all night by one of their famous Saturday night parties. In that case, who cares about how bad the engine is as long as it runs, and is extremely loud, and will rev to 2400 RPM. Just make sure to bump the governor before shifting. The neighbors have earned it.
First thing I look for is where the air enters the cylinder at. If it enters at the top, I shy away. If it enters through a ring of ports just above bottom dead center and has to be pushed there by a roots blower, I'm in.
The older trucks will smoke upon startup. Old 70s and 80s will smoke blue or grey for a while if cold. I own a old 400 Cummins and it will smoke for 20 to 30 minutes or until it's warm and that's just how it is. I rebuilt mine around 40,000 miles ago and it will smoke when cold until it gets to 160° still and everything is new. Nature of the beast with these old engines especially when timing has been retarded or low compression pistons are installed like mine.
Yep same with older tractors. Later 20 and the 30 and 40 series John Deere’s are notorious for blue smoke at idle when the engine isn’t at operating temp. they will fog out a shed in no time . Nothing wrong with them thats the way they are .
There are a few more rules when dealing with a used DPF engine: The failed DPF will damage the rest of the engine, so if you find a problem in a DPF engine be alert. The rise in backpressure destroys the turbocharger. In other cases, the turbocharger fails and the leaking oil ruins the DPF. If the engine does not use an injector in the exhaust system, it will inject extra fuel to get the DPF into active regen mode. If that happens too often, it wears out the piston rings and bores due to excessive unburnt fuel in the cylinder. Other times, the piston rings reach the end of their life, lead to excess oil consumption, and then clog up the DPF. I don't know how to separate all the different issues to solve the problem. Maybe you need a DPF, maybe you need to rebuild the whole engine and then replace the DPF. It really sucks that doing a compression test is either impossible or extremely time consuming on most modern diesels. 7:20 Diesel engines in many cars and pickup trucks always routed the blow by into the intake manifold or turbocharger. On the old ones, you could easily see where a hose was routed to the intake, then you could remove the hose and observe. 8:15 The other flaw in coolant test strips is that they don't tell you what type of additive package the coolant uses. Many years ago, Honda dyed their coolant green, and people would use the silicate based green antifreeze that was made for American cars. The result was water pumps failing too soon. There are other problems with the wrong coolant, but the example I used happened in my family. Gasoline or diesel, you must have the correct type of coolant and if applicable, coolant additives. Do any of you guys watch the "Powerstrokehelp" channel? People who own or work on diesel engines should also watch that channel even if they don't have a Ford or Navistar. 9:20 Excessive DPF active regen leads to excess fuel in oil if the engine doesn't use a fuel injector in the exhaust system. That is one thing that should be mentioned when you mention checking for excess fuel in the oil. It is extremely important.
We before we bought our kenworth t800 with a cat 3176 we test drove the carp out of it for three hours before we bought it and then we took it in the shop and crawd all arou d it with a light for leeks and made a list of thimgs wrong with it and told the dealer to fix it or back down on the price we also run a 3406 we love it as much as the 3176
I've read some horror stories about some of the really old Diesel engines from the '80s before electronic fuel injection was even thought of. In those cases engine manufacturing date is absolute key, as the manufacturer will try to revise issues as new engine developments come about, such as hydraulic roller lifters, single piece rear main seals, and serpentine belt drives that greatly improve engine reliability and reduce undue stress and load on the engine. This is the case with some older Chevy half ton Diesel trucks with Detroits in them, as engine developments for small block V8s were also being shared with the Detroit Diesel counterparts. Still doesn't mean that the crank has absolutely no problem with eating itself alive and destroying main casting webs in the process, turning essentially what sounds like a brand new engine into a heaping pile of metal on the highway. Diesels are subject to a lot more vibration and knocking than a gas engine even when not under load, so adding more revisions to eliminate vibration will lengthen the engine's lifespan. If you see a bulging or torn harmonic balancer, or a v belt setup, avoid at all costs. buying the most updated block of the same type to rebuild and drop in is gonna be more cost effective, install a hydraulic harmonic balancer, replace the main bearings, rebuild the injection pump, girdle the main block webs, and use a dual electric fan with an oversized aluminum radiator, so the clutch fan isn't robbing the engine of power, and you'll have a pretty good reliable engine that should see around the same mileage as a tractor trailer.
My old 6.2 treated me well but I've had my 6.5 for about a year now. Most reliable diesel I've ever had but I've done a few mods. Fluidamper being one of them :D
Is a good thing I didn't watch this before I bought my 07 ram 6.7... had a p2262 code. Issue was bent viens on the vgt replaced them for 200 bucks no more code running perfect! I'm just a backyard mechanic working on my own stuff..
I have a 1993 f350 idi when I bought it I didn’t know anything about Diesel engines ever since I remember had bad blow by and a rear mean seal oil leak I don’t really burn any oil It does smoke like crazy when cold and takes forever to get to temperature I guess I got lucky with the truck but I haven’t had that many problems with the old truck like I do with my 2006 Duramax
Hey Jay, Thank you for taking time to educate people like me that know little to nothing about Diesel engines. I have owned two diesel motorhomes with cummins 400 non def and current coach is a Cummins 450 with DEF. My question: I’m looking at 2 other older coach’s with 2007 CAT 350 rear rad.and the other has a 2006 400 CaT with side rad. Which of the Cat engines
I've got a CAT C11. It starts and idles strong. It could idle all day and no blow any smoke. When we get into higher RPM's after about 20 minutes it starts to blow white smoke and it sputters a little. I've drained the tank, changed the filters, tried the water treatments. I can't for the life of me figure out what it is. As soon as we lower the RPM's and get back to and idle it clears up again almost instantly. What would you think? I'm not losing coolant.
You fill my Brain lol Thank you. Soon to be on the road in a 2001 school Bus 366 turbo Cat.all good so for . thanks to your Video's help us pick the right Bus for the RV Build.
I was told to hold the dipstick vertical to see how fast it drips off the stick, if it's diluted it will run faster, but needs to be done while the engine is cold. Does this have any merit?
Will you do a video on the right way to disable the EGR? It has been clearly established that the EGR significantly shortens engine life AND fuel economy all in the name of reducing NOX. Thanks.
I wouldn't suggest getting someone to "disable" your egr... I give this advice both as a fellow diesel mechanic and the son of a semi driver.... HUGE FINES if you get caught.
You're gonna need to take it to a tuner's shop or do it yourself because this is illegal for on-road use. At least Michigan doesn't have emissions testing...
We just ended up rebuilding 3 engines. All 3406E. They all had around about 1.5 million miles. All water issues. Either sucking it in or blowing it out. Is that about right for lifespan of a good cat motor? The one motor with big horsepower numbers( turbo, injectors and a hot cam) was blowing it out but the others it was pulling it into the oil pan.
I love your site and advice just joined yesterday ive been looking to buy a 1998 thru 2002 chevy GMC 6500 rollback towtruck with the cat 3116 or the 3126 ive owned them before was years ago but they were great trks very easy to get used parts or new reasonable but there really getting hard to find reasonable were if it does need these things im buried in it so i found a 1998 chevy 6500 170k miles rollback the owner has had it for almost 11 years to transport cars to the auction so hes only put around 20k miles on it in all that time but the beds in great shape no rust interior is like new cabs dry its a eaton fuller 6 speed im fine with that actually have a spare sitting if needed so u no the truck O its a 3126 so heres the bad its smoking everywhere from all over under the hood when running now im over 300 miles away from this truck i no u cant give me any diagnosis when i personally haven't seen this truck just alot of pictures so my question is not about fixing it its about worse case motor swap i can buy 2002s gmc school buses this company has fleets and there selling them running driving home buses there automatics and there $2500 out the door so how do i tell horsepower or torque numbers is there a 3126 that u would want on your 1998 6500 if u were buying or building one i no rebuilt new is the way to go but in my situation rite now im on a budget i need a year so if i follow your advice from this video and i get the best one they have i no i have enough parts to make my truck a driver plus some extras like the rear the Alcoas with like new tires and its gotta return $600 in scrap when im done i really enjoy your videos and respect your knowledge you break it down into layman's terms makes it really easy to understand I just actually wondered if u were in my shoes what cat 3126 would u be looking for and its gonna be on the highway alot for power plus decent fuel sorry for this extremely long question i have a bad habbit of talking alot myself i hope u even see this hopefully u do either way keep up the great videos thanks again JOHN
Hey thanks for the video very informative and helpful I have a question I drive a 2015 International straight truck it has the n 13 engine buy Navistar with the def system what's your opinion on these engines I know the older maxxforce 13 what a pile of poo have you heard of people having the same issues with the newer def system on the N 13?
Hay love you videos, very informative. Which route do you think is best when it comes to a C15. 2007 out of frame overhaul (NSX) or 2006 out of parts yard (DSX, with paperwork showing overhaul)?
Do you recommend a Cat, Cummins or Mercedes diesel engine? Which one is most cost-effective to repair? I'm looking to buy a 2007 or newer school bus and personally like the CAT C7 sounds.
Just note that if it has a C7S in it, swap that for an older C7 or even a new C7.1 industrial engine. Otherwise, delete the emissions itrms. C7S's are notoriously unreliable when it comes to the emissions systems.
Cruise control works for a minute sometimes.. then it cuts off. Sometimes it works for days on end without cutting out. Very strange. Replaced Speedo sensor on tail shaft. Still cuts out
MINE IS A 1979 3208 CAT. MY TRUCK HAS ALOT OF OIL COMING OUT IN EXCESSIVE SMOKE. I PUT A LONG HOSE REROUTING IT AND THE WHOLE ENG DEP IS DRENCHED IN BLACK OIL.
Hell Diesel pros I own a 2006 F350 with a 6.0 powestroke I love the truck and I had no real problems other than some codes that Come on and I mostly ignore as it the past the codes won’t stop. I do need a mechanic to do real diagnostics and a real service. Any idea how to find a good Diesel mechanic in Jacksonville Florida?
When my Detroit glider is cold it blows alot of blue smoke uses no oil. Blowby tube blows smoke when its cold out as well. Smells like burning oil. So i bought another 12.7 from factory . I have the same problem if i didnt know better they never took engine out. All bolt on components are the same from old engine bolted to new
Our shop is pretty much full service, we don't do everything, but other than Cat engines, we do brakes, suspension, electrical, HVAC, and drive line. I think I had way too many commas in that previous sentence.
I have a 2006 c7500 with 3126 cat it cranks and runs fine doesn't smoke at all has 123k miles x AT&T truck so governor at 68mph. It blows oil out of the blowby tube at a fairly high rate seams like something is putting pressure on the block checked turbo replaced crank vent filter. any help would be appreciated
I have heard that there are numerous military surplus 6.2 and 6.5 engines from their HMMVs. Those engines have 24V glow plug systems, but you can swap those out for 12V systems.
By Some chance " Ape " And believe me I mean that in a Very Positive way, Do you Teach Diesel Engine Maintenance in a School for Diesel Mechanics or you have at some time. I could only think that if you have not Your doing Better with You Tube than you would in a School teaching new Diesel Trainees the Breathing Life of A Diesel Engine. Now I am Not a Teacher on Diesels or Gas Engines but I have and I am Semi Self tough Gas Engine Mechanic, and have worked on Radial Aircraft Engines and Gas Generators. I know the Principal and the Difference in Gas And Diesel Engines But I would not know where to Start On a Diesel Engine, If Your Not A Teacher Somewhere on Diesel Engines you Should Be. You are the Best I have ever Listened to When Explaining the Ins and Outs of a Diesel Engine, All i can Say is I have Told Many People About you and I do Know several of them are Subscribers of Yours and they all think you are Great. I am going to Buy a Diesel RV Here soon and I have Been Getting a lot Of Great Information from You and I thank you very Much. If Your Not a Teacher of Diesel Mechanics you should Be, What more can I say, Except If There is anyone out there that wants to Be A Diesel Mechanic Subscribe to this Channel " Adept Ape " this Man knows what he Is Talking about. Thanks Again. God Bless America its Disabled Veterans and Its American Patriots.
I have a Toyota 3L 2.8 blows no smoke except a little black underload ...no oil in coolant ..no coolant in oil...no leaks anywhere...goes great...but uses 1 litre of oil per 1000k...any ideas? PS fuel economy is good too 13 k's per litre for a slwb van.
I have a c13 my starter will click but won't start ,I have to click a few times and then she will.start, batteries are brand new, u think it might be the solenoid on the starter?
Also brother I get my oil sampling done on a regular and every time they say it’s at acceptable lever Continue on next oil change is that normal I have a 2005/2006 MxsC15
I have a 2005 w9 with a 550 acert ..my fan will stay on all the time if I don't unplug the AC compressor.. I brought it too 3 me shops and there best guess was to run a switch to manually engage the fan when it hits around 200 ..any suggestions on what it may be ..so far changed the fan hub/clutch and condenser..ended up running a switch so idk from here ..don't have the money right now to change the compressor..think it may be that?
Hello Aaron, your engine ECM controls your cooling fan and it must be getting an AC on signal from somewhere. Try unplugging your AC pressure switches and see if it kicks off, if it does, then you probably have a bad AC switch. If it still stays on then you may want to get the ECM programmed to not turn the cooling fan on with an AC signal or you can go through the time consuming process of trying to find out where the AC signal is coming from.

I spent a formidable part of my life as a heavy duty mechanic.
A side bar to this video is, a broken truck is not a deal breaker but a price adjuster. I prefer to buy trucks that require some sort of repairs prior to being usable. I’ve bought my truck with blown bearings in the bull gear. A relatively simple repair. But a lot of guys figure dump the truck.
Are you still fixing trucks?
Blown bearings in the bull gear?
I agree. I'd rather buy a truck needing an overhaul than one that was just overhauled? Do you think they did a quality job right before they sold it?
One other thing to look for is correct fastener use...are all the bolts holding down the part the same? Most engines don't hold down a part with different kinds/styles of fasteners. Its a red flag for a shoddy repair and that repair ethos probably follows through to other repairs & maintenance.
bought used 1997 e350 7.3.
heavy gray smoke.
esp when cold.
i changed oil& filter every 69 days for 2 years.
2 years later it runs like a demon and no smoke. still change oil every 10 k miles. its got over 495 k miles and no problems and wil out pull every truck on the road up to 12/25/18

What diesel idles at 2-300 rpm.
In the high speed arena which is what most equipment is
Saw it done many times.
Older districts almost always had an emergency air flap mounted above the super charger.It was activated with either a cable or electric solenoid. You could trip it by hand and make it look like it wasn't done. No air getting in to burn the fuel.
Cummins might have a emergency fuel stop. Activated the same was. I have seen somebody turn the fuel off or almost off, then loosen the nut on arm and reset it look open.
Put tape on the terminal and on of the fuel solenoid so it doesn't open.
Man I LOVE coming home to see that you've made a new video.
Aww thats really sweet
Just bought a 2000 Freightliner......1.3 million, in wonderful condition, has Destroit 12.7 in it that runs but it's getting on towards that time.....
To build a scary motor, tee hee!
I learn so much basic shit from your videos, and I've been doing this for almost fifty years, that I'd like to thank you.
Wolfi Lewis i heard 12.7 parts are cheap compare to cat n cumm aparts
Great job. That video will be very helpful for a lot of people!

Never trust your buddy with your diesel or your old lady. He’ll sling a rod in both of them.
Wayne Swicegood lol best comment ever.
Friggin hilarious!
😂😂
Thanks Wayne you Made me laugh.
Took me a moment, but you made me smile...thanks
I don't even have a diesel, now I'm scared to death to get a used diesel RV or truck.
Thanks for the videos. (I quit pre-filling my oil filters)
Patrick McLaughlin gas or diesel the risks are the same, most of the advice is the same as well.
Same thing for buying a used car. The engine is very telling.
Simply 1 of the best video on d engines

Nature of the beast with these old engines especially when timing has been retarded or low compression pistons are installed like mine.
My grandfather usually when waking up also smoke like hell Paramount cigarettes and coffee
Pretty much any pre-emissions or deleted Diesel running on used engine oil will smoke on startup as well.
Yep same with older tractors. Later 20 and the 30 and 40 series John Deere’s are notorious for blue smoke at idle when the engine isn’t at operating temp. they will fog out a shed in no time . Nothing wrong with them thats the way they are .
Io need to take this guy truck hunting with me. Great information!
Great video, as always. You are such a library of knowledge

8:15 The other flaw in coolant test strips is that they don't tell you what type of additive package the coolant uses. Many years ago, Honda dyed their coolant green, and people would use the silicate based green antifreeze that was made for American cars. The result was water pumps failing too soon. There are other problems with the wrong coolant, but the example I used happened in my family. Gasoline or diesel, you must have the correct type of coolant and if applicable, coolant additives.
Do any of you guys watch the "Powerstrokehelp" channel? People who own or work on diesel engines should also watch that channel even if they don't have a Ford or Navistar.
9:20 Excessive DPF active regen leads to excess fuel in oil if the engine doesn't use a fuel injector in the exhaust system. That is one thing that should be mentioned when you mention checking for excess fuel in the oil. It is extremely important.
Or just delete the DPF entirely. And the EGR.
@@electric7487 That's great if you don't need your truck to be street legal.
Nope not how any of that works. Lmao I can't believe you literally typed out all of that completely wrong information 😂😂😂
Thanks for sharing 👍🏿
Tell me could you please make a video on what to look for when buying a 24' box trucks 👍🏿
Another great video from my favorite diesel you tube channel
What's the pros and cons cat,cummins,Detroit?
We before we bought our kenworth t800 with a cat 3176 we test drove the carp out of it for three hours before we bought it and then we took it in the shop and crawd all arou d it with a light for leeks and made a list of thimgs wrong with it and told the dealer to fix it or back down on the price we also run a 3406 we love it as much as the 3176
Have gotten some good fuel mileage from the C7 CAT engine and the 500 HP DOUBLE D as WELL
Ask and watch the dealer rep run when you want them to hookup and print out the ecm.
So many people buy a truck or car and never open the hood. Obvious things like low oil and rusty coolant are easy to spot.
I've read some horror stories about some of the really old Diesel engines from the '80s before electronic fuel injection was even thought of. In those cases engine manufacturing date is absolute key, as the manufacturer will try to revise issues as new engine developments come about, such as hydraulic roller lifters, single piece rear main seals, and serpentine belt drives that greatly improve engine reliability and reduce undue stress and load on the engine. This is the case with some older Chevy half ton Diesel trucks with Detroits in them, as engine developments for small block V8s were also being shared with the Detroit Diesel counterparts. Still doesn't mean that the crank has absolutely no problem with eating itself alive and destroying main casting webs in the process, turning essentially what sounds like a brand new engine into a heaping pile of metal on the highway. Diesels are subject to a lot more vibration and knocking than a gas engine even when not under load, so adding more revisions to eliminate vibration will lengthen the engine's lifespan. If you see a bulging or torn harmonic balancer, or a v belt setup, avoid at all costs. buying the most updated block of the same type to rebuild and drop in is gonna be more cost effective, install a hydraulic harmonic balancer, replace the main bearings, rebuild the injection pump, girdle the main block webs, and use a dual electric fan with an oversized aluminum radiator, so the clutch fan isn't robbing the engine of power, and you'll have a pretty good reliable engine that should see around the same mileage as a tractor trailer.
My old 6.2 treated me well but I've had my 6.5 for about a year now. Most reliable diesel I've ever had but I've done a few mods. Fluidamper being one of them :D
Is a good thing I didn't watch this before I bought my 07 ram 6.7... had a p2262 code. Issue was bent viens on the vgt replaced them for 200 bucks no more code running perfect! I'm just a backyard mechanic working on my own stuff..
I have a 1993 f350 idi when I bought it I didn’t know anything about Diesel engines ever since I remember had bad blow by and a rear mean seal oil leak I don’t really burn any oil It does smoke like crazy when cold and takes forever to get to temperature I guess I got lucky with the truck but I haven’t had that many problems with the old truck like I do with my 2006 Duramax
Hey Jay, Thank you for taking time to educate people like me that know little to nothing about Diesel engines. I have owned two diesel motorhomes with cummins 400 non def and current coach is a Cummins 450 with DEF.
My question: I’m looking at 2 other older coach’s with 2007 CAT 350 rear rad.and the other has a 2006 400 CaT with side rad. Which of the Cat engines
Sorry.. any particular issues with either of the CAT engines I mentioned ?
I have a test kit that checks for exhaust gases in the radiator, it is quick and sample.
I've got a CAT C11. It starts and idles strong. It could idle all day and no blow any smoke. When we get into higher RPM's after about 20 minutes it starts to blow white smoke and it sputters a little. I've drained the tank, changed the filters, tried the water treatments. I can't for the life of me figure out what it is. As soon as we lower the RPM's and get back to and idle it clears up again almost instantly. What would you think? I'm not losing coolant.
You fill my Brain lol Thank you. Soon to be on the road in a 2001 school Bus 366 turbo Cat.all good so for . thanks to your Video's help us pick the right Bus for the RV Build.
Great Video ‼️….where is a Good place to have my C15 injectors Reman?
I was told to hold the dipstick vertical to see how fast it drips off the stick, if it's diluted it will run faster, but needs to be done while the engine is cold. Does this have any merit?
I knew I bought a 2006 RV for a reason. No DPF or DEF. just a smooth cat!!!
Great video. You are very experienced mechanic.
Love your content brother! And are Big Cam Cummins a good motor? Looking at a strong runner in a cab over!! Be safe out there man and again thank you!
Will you do a video on the right way to disable the EGR? It has been clearly established that the EGR significantly shortens engine life AND fuel economy all in the name of reducing NOX. Thanks.
Robert Polkamp disabling egr is illegal so it's unlikely he will ever make such a video.
I wouldn't suggest getting someone to "disable" your egr... I give this advice both as a fellow diesel mechanic and the son of a semi driver.... HUGE FINES if you get caught.
You're gonna need to take it to a tuner's shop or do it yourself because this is illegal for on-road use. At least Michigan doesn't have emissions testing...
Thanks for making a sensible video!
We just ended up rebuilding 3 engines. All 3406E. They all had around about 1.5 million miles. All water issues. Either sucking it in or blowing it out. Is that about right for lifespan of a good cat motor? The one motor with big horsepower numbers( turbo, injectors and a hot cam) was blowing it out but the others it was pulling it into the oil pan.
1,500,000 miles is a fantastic achievement. Someone had to be performing good preventive maintenance for that to occur. Great job.
C12 is 20000 hrs or 800,000 kilometers when due for rebuild
I love your site and advice just joined yesterday ive been looking to buy a 1998 thru 2002 chevy GMC 6500 rollback towtruck with the cat 3116 or the 3126 ive owned them before was years ago but they were great trks very easy to get used parts or new reasonable but there really getting hard to find reasonable were if it does need these things im buried in it so i found a 1998 chevy 6500 170k miles rollback the owner has had it for almost 11 years to transport cars to the auction so hes only put around 20k miles on it in all that time but the beds in great shape no rust interior is like new cabs dry its a eaton fuller 6 speed im fine with that actually have a spare sitting if needed so u no the truck O its a 3126 so heres the bad its smoking everywhere from all over under the hood when running now im over 300 miles away from this truck i no u cant give me any diagnosis when i personally haven't seen this truck just alot of pictures so my question is not about fixing it its about worse case motor swap i can buy 2002s gmc school buses this company has fleets and there selling them running driving home buses there automatics and there $2500 out the door so how do i tell horsepower or torque numbers is there a 3126 that u would want on your 1998 6500 if u were buying or building one i no rebuilt new is the way to go but in my situation rite now im on a budget i need a year so if i follow your advice from this video and i get the best one they have i no i have enough parts to make my truck a driver plus some extras like the rear the Alcoas with like new tires and its gotta return $600 in scrap when im done i really enjoy your videos and respect your knowledge you break it down into layman's terms makes it really easy to understand I just actually wondered if u were in my shoes what cat 3126 would u be looking for and its gonna be on the highway alot for power plus decent fuel sorry for this extremely long question i have a bad habbit of talking alot myself i hope u even see this hopefully u do either way keep up the great videos thanks again JOHN
so good media knowledge
Hey thanks for the video very informative and helpful I have a question I drive a 2015 International straight truck it has the n 13 engine buy Navistar with the def system what's your opinion on these engines I know the older maxxforce 13 what a pile of poo have you heard of people having the same issues with the newer def system on the N 13?
Very well done 👍 thx
I’m starting to buy and sell diesel trucks. Can you give me a lot of tips? Thanks.
Thanks for the great advice
Hay love you videos, very informative. Which route do you think is best when it comes to a C15. 2007 out of frame overhaul (NSX) or 2006 out of parts yard (DSX, with paperwork showing overhaul)?
Do you recommend a Cat, Cummins or Mercedes diesel engine? Which one is most cost-effective to repair? I'm looking to buy a 2007 or newer school bus and personally like the CAT C7 sounds.
Just note that if it has a C7S in it, swap that for an older C7 or even a new C7.1 industrial engine. Otherwise, delete the emissions itrms. C7S's are notoriously unreliable when it comes to the emissions systems.
I watch this dude to help me sleep
You got a new subscriber ..
Great video
If someone hallowed out a DPF is that a “poor man’s” delete? Would that really be a problem?
Hi thanks for the great video. What about oil leaks on a diesel? And are Detroit Diesel engines are supposed to be one of the best diesel engine?
Cruise control works for a minute sometimes.. then it cuts off. Sometimes it works for days on end without cutting out. Very strange. Replaced Speedo sensor on tail shaft. Still cuts out
MINE IS A 1979 3208 CAT. MY TRUCK HAS ALOT OF OIL COMING OUT IN EXCESSIVE SMOKE. I PUT A LONG HOSE REROUTING IT AND THE WHOLE ENG DEP IS DRENCHED IN BLACK OIL.
Very nice!
Great job, thanks!
things i have repaired... 4 seals in oil cooler and power steering hoses.
NOTHING ELSE!
Thanks
Nice helpful video. Thanks
White smoke or steam is a head gasket probability also
I have a 1996 Freightliner fld. I have light smoke coming out of the oil dipstick. Is this bad?
Thanks for the info.
What's your experience on tier 4 cat equipment like DPF?
I run an old big cam with a turned up fuel pump black clouds everywhere I go below 1500 rpm but runs like a top
Hell Diesel pros
I own a 2006 F350 with a 6.0 powestroke
I love the truck and I had no real problems other than some codes that Come on and I mostly ignore as it the past the codes won’t stop.
I do need a mechanic to do real diagnostics and a real service. Any idea how to find a good Diesel mechanic in Jacksonville Florida?
Thank you...
Great Vid ! Thank you
Really good video thank you
So a littel bit of white smoke coming out of the blow by tube isnt bad right on a 60 year old engine (perkins 4.236)
I love u bro,God bless u
Ya should be able to trust his advise. He has dogs and puts them to in his videos. 👍😜🤣
When my Detroit glider is cold it blows alot of blue smoke uses no oil. Blowby tube blows smoke when its cold out as well. Smells like burning oil. So i bought another 12.7 from factory . I have the same problem if i didnt know better they never took engine out. All bolt on components are the same from old engine bolted to new
Do you strictly work on engines at CAT or do you do full truck repair like airbags and brakes?
Our shop is pretty much full service, we don't do everything, but other than Cat engines, we do brakes, suspension, electrical, HVAC, and drive line. I think I had way too many commas in that previous sentence.
Irregardless is not a word. It's just regardless.
If your DPF fails on a Hino, Itll go into limp mode. Cant go over 25
Who cares
You are so similar to Ben Schepiro, sound and look like him a bit it’s weird 😂 You are the Ben Schepiro of Cat Diesels
I have a 2006 c7500 with 3126 cat it cranks and runs fine doesn't smoke at all has 123k miles x AT&T truck so governor at 68mph. It blows oil out of the blowby tube at a fairly high rate seams like something is putting pressure on the block checked turbo replaced crank vent filter. any help would be appreciated
I need a GM 6.2L engine for my 1987 Suburban V2500. Which rebuilders are reliable? Or is there a reliable source for a used engine?
I have heard that there are numerous military surplus 6.2 and 6.5 engines from their HMMVs. Those engines have 24V glow plug systems, but you can swap those out for 12V systems.
I think the Detroit Diesel the 500 horsepower Detroit Diesel is much more noisier than the C7 caterpillar Engineers by a long shot
Cat cummins or Detroit 60 for rvs…any thought…
Nice best video
Thank you.
What about using an automotive stethascope on a diesel?
By Some chance " Ape " And believe me I mean that in a Very Positive way, Do you Teach Diesel Engine Maintenance in a School for Diesel Mechanics or you have at some time. I could only think that if you have not Your doing Better with You Tube than you would in a School teaching new Diesel Trainees the Breathing Life of A Diesel Engine. Now I am Not a Teacher on Diesels or Gas Engines but I have and I am Semi Self tough Gas Engine Mechanic, and have worked on Radial Aircraft Engines and Gas Generators. I know the Principal and the Difference in Gas And Diesel Engines But I would not know where to Start On a Diesel Engine, If Your Not A Teacher Somewhere on Diesel Engines you Should Be. You are the Best I have ever Listened to When Explaining the Ins and Outs of a Diesel Engine, All i can Say is I have Told Many People About you and I do Know several of them are Subscribers of Yours and they all think you are Great. I am going to Buy a Diesel RV Here soon and I have Been Getting a lot Of Great Information from You and I thank you very Much. If Your Not a Teacher of Diesel Mechanics you should Be, What more can I say, Except If There is anyone out there that wants to Be A Diesel Mechanic Subscribe to this Channel " Adept Ape " this Man knows what he Is Talking about. Thanks Again. God Bless America its Disabled Veterans and Its American Patriots.
Thank you for the compliment sir. I'm glad you are pointing people at the channel too. The more it grows the better the content I can put out there.
I have a Toyota 3L 2.8 blows no smoke except a little black underload ...no oil in coolant ..no coolant in oil...no leaks anywhere...goes great...but uses 1 litre of oil per 1000k...any ideas? PS fuel economy is good too 13 k's per litre for a slwb van.
I have a c13 my starter will click but won't start ,I have to click a few times and then she will.start, batteries are brand new, u think it might be the solenoid on the starter?
Question. Do you have a video of running the overhead on the c15 engine
Also brother I get my oil sampling done on a regular and every time they say it’s at acceptable lever Continue on next oil change is that normal I have a 2005/2006 MxsC15
I have a 2005 w9 with a 550 acert ..my fan will stay on all the time if I don't unplug the AC compressor.. I brought it too 3 me shops and there best guess was to run a switch to manually engage the fan when it hits around 200 ..any suggestions on what it may be ..so far changed the fan hub/clutch and condenser..ended up running a switch so idk from here ..don't have the money right now to change the compressor..think it may be that?
Hello Aaron, your engine ECM controls your cooling fan and it must be getting an AC on signal from somewhere. Try unplugging your AC pressure switches and see if it kicks off, if it does, then you probably have a bad AC switch. If it still stays on then you may want to get the ECM programmed to not turn the cooling fan on with an AC signal or you can go through the time consuming process of trying to find out where the AC signal is coming from.
Thanks man just bought it ...and a little amount of blow by is normal right ?
forgot: i have replaced all the dual tires on rear 4 times and due again. front michlan tires are still good.
wow. (see next comments)
Adept Ape what you think about glider kit?
