I was shocked that GM chose a belt for oil pump on the 3.0 Duramax. I wonder if Isuzu had been the major on the 3.0 like they were(are?) on then6.6 Dmax, if a belt would have been used.
Eric - my father-in-law is visiting today, and went to the store. When he returned he said he found something in the parking lot and held out his hand. He had found a socket. I said "let me guess. Is it a 10 mm?" He looked surprised and asked me how in the world I guessed the size. It was from watching your channel and learning that 10 mm sockets run away at night.
When you say you would sell it as a builder what do you mean by that? Do you mean like you put all of the parts in a bin or 2 and sell it complete minus the maintenance parts
@@smoothlover073builder really just means you could send it to the machine shop for a rebuild and they wouldn't call you up to tell you it can't be saved
@@daviddorge1559 never heard of the little end wrist pin needing oil pressure... clearance of a pin is usually only thou or two. Bigger clearance will cause more of a hammer blow at TDC firing?

Had to be wear in the pin holes in the piston, given the pins are a seize fit in the rods....unless it wasn't a seize fit any more of course. Can't imagine how oil pressure would affect pin clearance? But, yes, would be nice to have that investigated a bit more.
As soon as you said why would somebody take a water pump and reuse it. I thought well that the engine overheated. Because it had a bad water pump. They replaced it and then the engine died. So the water pump wasn't that old. So they took it and put it on the used engine. Now I'm making this, 20 minutes into the video I could be totally wrong I have been before. So if you are taking apart a good engine why don't you rebuild this one that'd be a treat for the channel.
Installing used pumps of any kind is a dumb liability for a shop. A "chain of custody" is more important than "saving a buck" if you are standing behind your work.
But do we have any proof that a shop did the work? At the age of 58 I retired and sold our 12 Bay body shop. I have seen a lot of weird things owners of cars and trucks have done.
Probably replaced engine because that piston wrist pin wear was causing knock, and the ECU, thinking this was detonation, due to the timing on that cylinder, had pulled power way back. Then the lowered fuel input meant the cylinder was running ultra lean, and this, combined with probably a small carbon particle that got stuck on the valve, caused it to wear, and then the ECU carried on running that cylinder ultra lean, leading to the valve seat eroding as the combusting fuel mix kept on bleeding by. You can see the run marks of the metal being eroded away. Engine replaced because ECU told of misfire on one cylinder, bad knocking and lack of power, along with very lumpy idle. Compression test said cylinder really bad on leak test, so scrap engine instead of stripping head, because the used engine is cheaper than a strip, repair and assemble labour wise. Pump likely removed because it was faulty on the junkyard engine, probably leaking water, so to cut cost they swapped with the old one.
@@jamesgeorge4874 do you understand how ridiculous you should? If you buy a used vehicle do you replace every used pump of any kind? Educate the comment section on just how the water pump would be untrustworthy in the OP's theory, I dare you...FFS.
A Ford engineer would tell you "We pulled $1.29 out of each engine by using that belt instead of a chain" and the look on his face would tell you that he was PROUD of what he had done...
GM has done this many times. Putting a tranny designed for a CHEVY CHEVETTE (THM 200) in a big 77 Caprice Classic? NOT putting a vibration balancer on the 2.5 "Iron Duke" (except for a few at the end)? I heard GM once put PLASTIC sprockets in the dealership parts bins for some of the 1970s MONZAs, but I heard they were recalled because GM realized these were STUPIDLY BAD quality.

Never was a car guy or knew much of anything about them till I stumbled upon this channel. Watched every teardown over the past year and love knowing how my brand new Subaru works and how to protect it. Would love to make sure my boxer doesn't end up on this channel. Cheers bro,
Same here, I'm just some I.T. nerd. His recent GM 3800 video was suggested to me, I had 3 cars with that engine in the past, I thought what the heck. Then he has videos of known-problematic engines, so I watched those too, I've been hooked ever since. Funny how The Algorithm™ works LOL
I can't understand why they put so much resource and design in the casting, overly so IMHO, yet cheaped out on a fibre oil pump belt. But yet another great video, thanks Eric.
Because a bean counter did the comparasion, and the belt worked out to a few cents cheaper, plus it added 0.001MPG improvement in the standard test cell run.
I wouldn't wait on that oil pump belt service considering they start to shed debris that will clog up the oil pickup screen. If the previous owner short tripped the truck a lot, it will degrade much faster. They seem to break down faster due to exposure to unburned fuel in the engine oil.
@@hochhaul and there is no proof that they degrade faster with short trips and no proof that the belts shreds anything. Once again it could fall back to sloppy maintenance.
I have a collection of burnt exhaust valves on my "shelf of shame"... And every single one came from a stock engine with excessive oil consumption. Hard to say why this Ecoboost burned a valve. A bad injector would melt the piston long before a valve got torched 🤔
A turbo engine is like having a build in cutting torch....lol You can see the cutting lines on the valve like it was cut with a torch. Which it was by the turbo.
I don't remember if it was mentioned in any of the other 2.7 vids but the reason for the interesting block construction is because it's made from compacted graphite iron (cgi) which is significantly stronger than standard cast iron, it's the same type of iron that Nascar engine blocks are made from. It's really a shame other manufacturers haven't taken the plunge to invest in CGI blocks because it offers significant gains over standard cast iron. Also, the coating on the bearings was introduced into Ford engines (and likely other brands too) when they made auto start-stop systems standard to increase MPG ratings. The coated bearings hold up much better to repeated frequent restarts than uncoated bearings.
@@D3M0ify So what's wrong with a wet belt other than it's something none of us are used to seeing? Find us a wet belt 2.7L Ford that has blow up due to a failed wet belt. Crickets 🦗🦗
I work the service parts counter at a large Ford dealership and we would replace. It's faster to replace the engine than repair plus the customer gets a warranty. Aside from the oil pump belt and plastic oil pan, I think that Ford did a pretty good job with the 2.7L. I feel it is the least seen engine needing major repairs in the shop.
That's odd because I have a watched a couple of other videos of Ford mechanics where someone goes around and asked what motor they would buy and pretty much all them said the V8. I peryonoe 3 friends that have had there 2.7 "eco" boost motors blow up. One the dealer has to do two!
@@apwurst The 5.0L is also one of Ford's better engines. There is definitely less to break on the 5.0L plus you can't beat that V8 rumble. I think we have to understand though that Ford builds hundreds of thousands of engines every year so there will be a few with manufacturing defects.
@@doomspeaker1256 this is true. IF I wanted an F150, I'd go with the 5.0 just because I like the V8 burble/rumble. EcoBoost trucks don't have much of a voice out of the box.
I'd put money on that being the original problem, causing enough friction & wear on the chain guides to screw up the timing just enough to cook that valve. Just wish we could've seen what caused the slop in that one cylinder. 🤷♂️
Ahh but what would cause it o put MORE rather than less tension? How about some accumulated spooge pudding getting into the and behind the plunger. Just spitballing here as I’ve never seen this myself…..thankfully
@@phillipfritz7014 OK. I'll come clean. I actually have no idea what happened, so I just threw out a wild guess. Maybe I'm right, but I seriously don't know.
Your videos are great! I'm learning so much more about my Gen-1 2.7l EcoBoost Engine inside my 2017 Ford Fusion Sport than I ever will scouring random forums about my car. I have a 2017 Ford Fusion Sport and had to have that engine (2.7l EcoBoost Gen 1) replaced because it blew a head gasket and leaked coolant into the cylinders, but based on your past breakdown videos on both the Gen 1 and 2 2.7l EcoBoost engines, I have a more complete understanding of what makes this engine tick. The replacement engine costed almost $5k including labor to replace, luckily I bought an extended warranty that covered everything bumper to bumper when I bought the car. I bought this car second-hand off of Carvana, so I didn't know how this car was treated before me. I found out, after I bought the car, that the car had 1 quart oil low and there was no oil on the dipstick when I was getting an oil change, me being a buffoon and not knowing anything about my own engine at the time, ignored that warning sign. Six months later, my engine started consuming coolant and was emitting white smoke out the tail pipes, I was wondering if there was a leak or something, but I couldn't find a leak anywhere, come to find out the coolant was leaking into the cylinders. One cold morning, I was accelerating hard on the on-ramp on to a freeway, a giant cloud of white smoke covered the freeway and my engine completely shut down. That was when I knew the head-gasket blew and coolant flooded my cylinders. I think the previous owner of this car neglected the car and the engine and let it overheat from oil starvation. My car was in the shop for 6-months, because 2-months was searching for a replacement engine. Apparently this engine is hard to find. The 2.7l v6 EcoBoost is a marvel of an engine, paired with an AWD drive-train in a four-door car makes for some fun driving. I'm also happy to know that the Gen 1 2.7l engines have chains for oil pumps, although it doesn't have both Port and Direct injection, I'm okay with that. The replacement engine now gets an oil change every 3000 miles, I don't care about Ford's 5000 or 7000 mile recommendation. I'm not giving the replacement engine a chance to oil starve. The replacement engine is also now modified with a CAI, GFB+ Diverter Valve, and 93 gas tune. I've also upgraded the brake lines to Steeda Stainless Steel brake lines, I saw a manufacturer recall on how weak the front brake lines could be on this model and year car so I decided to upgrade all four brake lines to braided stainless steel. Keep your 2.7l and 3.0l Ecoboost videos coming. Your videos are super educational and you've got another subscriber!
I had a 2017 Lincoln MKX AWD with the Gen 1 2.7L turbo. It’s the same engine that is in your car and I agree it is a blast to drive and is a perfect match for a car that size and weight. It was probably OK in an F150 if treated very gingerly without any towing, but I would still have wanted a larger engine in a truck. I’m retired so I don’t drive that many miles, but after reading about the issues with that engine; only direct injection, plastic oil pan gasket issues and other assorted moderately expensive maintenance necessary at 60K, I got out of it early. If I had a 2018 or later, I probably would have kept it a little longer, but there were still too many potential problems so it was best to move on before the repair and big maintenance bills hit all it once.
Don't be hard on yourself. It's most likely that your 2.7 had the dreaded long block defect that plagued something like 1 in 3 2.7s for a few months of 2016 manufacturing. A supplier screwed up and delivered a batch of long blocks with uneven decks which caused the gaskets to eventually fail and leak coolant.
The 2.7 as a ford tech is my recommended engine from my anecdotal evidence and from other that have been around that place more than me. The 2.7 is the most reliable followed closely by the 3.5. they don't have manifolds so they don't have the warped manifold issues of the 3.5 they make less power so they aren't as stressed. But they also just don't fail. We tear down 5.0s all the time fro oil burning and the 3.5s for phaseres. The 2.7 has a slight issue but nowhere near as bad as the 5.0 or 3.5s. we've only done 1 2.7 and that's because of a faulty belt broke in the right way to snap off the oil pressure switch we've done a few 3.5s and way more 5.0s and the 5.0s are the least sold (I know the 2021 2.7s and up have valve shattering issues but I'm referring to gens 1 and 2)
Everyone keeps complaining about the rubber oil pump belt, but it looked totally fine at that mileage. What about all the cam chain tensioner failures. Chains are so much better? You need to change your oil every 5000 miles. Neglecting oil changes is what kills engines.
That's not true. They've known since the 60's that rubber and oil don't mix. I don't give af what "compound" Ford says they made these belts out of, they'll all crumble into oblivion before the 150k interval they claim it lasts. 50k miles and those belts are already swelling. Chains are infinitely better.
It really truly seems to me to be a ton of fear mongering for absolutely no reason. If the wet belt was truly an issue we’d see multiple videos, posts on forms and other things that indicate the wet belts are failing all the time but there just isn’t evidence for that. With the amount of people saying “wet belts are bad” you’d think it’s the worst design in the entire universe….
@@SammyM00782 The belts aren't rubber. 1960's belts and modern ones are totally different animals. Different materials, different designs. Just not an accurate comparison.
As to the question at the end, if I were the tech working on this as a customer vehicle, I would have recommended the engine too. We only get so much time to dig into a bad motor for diag. It’s no fun getting burned on a comeback for trying to save the engine.
Nice to see someone that doesn't just blindly follow the recommended OCI. Great to see the results of a reasonable OCI. 10k is too long for the dirtier fuel in the USA and lower grade synthetic oils. UOA should drive OCI for the application. 3k, 5k, or 7.5k max. If you tow change it sooner, etc. A car isn't just an expensive toaster.
I just love the brilliant design of these engines. Plastic drain plug that always leaks, with the sway bar directly in front of the plug. Once you pull that plug, it gushes out like on a Subaru, hits the sway bar and goes EVERYWHERE
The drain plug leaks because people reuse them. They're a service item and you're suppose to use a new one every time. Ford tells you this in the maintenance manual. You can invest in aftermarket unit like the Ronin drain plug that converts it to an all metal design that has a smaller orifice to drain out of, but honestly once you drain it once you know not to just rip it out as fast as possible, and to hold it like he did. Or just hold the bucket RIGHT up to it, and let it drop in there after you crank it off, and replace it with a new one like ford said. No mess, no oil everywhere, and it drains in like .7 seconds. Lol.
Injector failure, or at least malfunction. Created a hot spot in the chamber, turbo keeps pumping in air, hot spot gets really lean from not enough fuel, boom-burnt valve. This is the cost of very complex, highly dependent, high performance, small displacement engines. Everything HAS to work perfectly ALL the time, or it fails catastrophically.
The burnt valve was radically burnt, looking like it was blasted with a gas axe. You'd think the computer crap would report a loss of compression in that cylinder.
@@StuntPosse The computer will report a misfire on that cylinder. Not sure if the ECM will do a relative compression check on the gassers like it will on the 6.7 diesels.
Every time I see you do a 2.7t I get excited that it's an old Audi 2.7t from the b5 s4/c5 a6/allroad, and then I'm still happy because a lot of times these have spectacular failures! Love the work man, keep it up!
I am happy that I just bought a three valve 5.4 liter 2009 Ford f150. The timing components and oil pump were changed shortly before I bought it for $1700. It still was having timing issues. I found the cam position sensor connection plug was bad. i was so happy. It is perfect now.
I was quoting a MX13 for a 2025 Kenworth T680 yesterday. Engine was $63,000 and the core was $8,000. The truck has 6k miles on it and was in a crash bad enough to break the block
This is why companies like mine buy wrecks. We salvage all sorts of shit from them and use it to rebuild others. We can build up a truck with 10k miles for $100k when a used one with miles like that is $275k+ easily. Saves so much money.
You need to remember that those blocks are graphite composites. Strong internally, weak when outside forces are inflicted on it. I hear they are now making sleeve kits for when you have to inframe the engine instead of purchasing a short block.
It’s amazing how fast you pump out good quality content. When I’m waiting on everyone else to post i always have your videos pop up ad I love watching em.
For my money, with the way the rest of the engine looks, especially the lack of damage to the rotating assembly, I'd fix this one, no doubt. With a replacement you wouldn't be able to check these components, therefore it's an unknown quantity. For the difference in cost, the peace of mind would be with it, but that's just me. Great teardown, Eric. I've been wanting to know more about the Ecoboost platform, the 2.7 in particular, and you've answered a lot of those questions. Keep em coming, buddy!
The 3.8 liter engine in my Buick makes over 600 pound feet of torque at the tires on 28 psi of boost. High power in the small engines isn’t what kills them if they’re maintained right. My engine doesn’t have an oil pump belt though lol….
"Let's remove the lower block." Wait what is a lower block. Oh I see, WTF. Back in my day we just had a block and we were grateful. Love the teardown vids Eric. Liked and Subscribed. 🤘
As far as I know, the oil pump belt has not oil related problem, it has problem with short run time where its not warm and running rich. This makes some of the gas gets inside the oil and the gas is killing the belt.
I have an old 1994 Chevy 1500 pick up, it always needs something every 6 months or so even though I only put maybe 5K miles a year on it. When I look at the complexly of late model trucks and the price tags I stop my bitch fest fix my 100 to 300 dollar problem and close the Auto Trader screen on my computer
@@jamierose4088 Except the Tundra now comes with a standard 3.5 TT. What's amazing is how they essentially copied Ford down to the displacement but their 3.5s are having teething issues. Turns out when you're a lame company that coasts its reputation on old underpowered engines with lots of slop built in, you have a hard time designing a powerful and efficient engine when the market demands it.
@@spacebound1969while I will not agree with you 100%, I can't argue with with at least one good point you bought up. Ecoboost are super fun to drive and they are pretty quite and smooth. Every toyota I drove was loud and rough but I imagine reliable. If I'm watching Dave ramsey I will buy a toyota. If I'm not I will buy a ford.
@@spacebound1969 One evening in 2009, I met a Ford engine department engineer, so we talked about...engines. He said that the Toyota 4.0L V-6 (in my '06 Tacoma) was one that Ford BOUGHT to study. He also said that the crank angles were critical to making power. I'm sure he was right, but that V-6 was just mind-boggling with its flexibility and power. Mine was a 6 speed manual with towing gears. There was almost no situation where any of 3 gears wouldn't work fine. The one thing to avoid was going up a freeway onramp in 2nd gear, because it accelerated so hard in 2nd and finding 3rd wasn't to be rushed. MPG wasn't great, and was pretty much the same as its replacement, an '08 Silverado 4x4 with 5.3L. Range is better with the Silverado. There are some things I don't like about the 5.3L, but it's relatively simple. The complexity of the newest Ford engines pretty much makes them throw-aways, IMO. Would be fun to install in an older european car, like a Cortina or even BMW. I've driven a couple of BMW's and really liked them, but could never afford to own one. 😪
There is a more important reason why the piston rods are offset. It allows for better geometry in the position of the crank shaft and rod during the compression stroke.
Referencing your last 2.7 teardown if it was do to small displacement and high HP. Auto makers that make all of the high hp 4 cylinder engines would fail to based off that assumption, which is not true. There are alot of 2.7 ecoboost engines with high mileage. Its that old mentality mechanic that assumes that like scotty kilmer he will tell you to buy nothin but a naturally aspirated toyota from the 90s. Tech has changed so much over the years that is why i have the 2.7 and its been a great motor. Thanks for the videos 👍!
I have the big brother to this engine. The 3.0, in my explorer ST. I’ve had my engine tuned with FBOs and it makes about 520 hp at all four wheels. I did this at about 3000 miles. It has about 32,000 miles and the only mechanical problem I’ve had is a sensor with the all-wheel-drive system leaking. The 10R60 transmission is another story. These engines make amazing power. Turbos, fuel pump and a tune will get an explorer into the high tens. The 3.0 v6 TT seems to be the Magic number for power. A lot of new manufactures are making a 3.0 i6 or v6 TT
the more i see of these 2.7's the more i like them. the coolant crossover tube in the back and clean valves from the port injection addition is really nice!
fwiw my work truck is also a 2018 2.7, and i use all 400 ftlbs that thing makes 5-6 days a week, 50-200+ miles a day. i drive that thing like its a racecar, pedal to the metal, if its not idling its redlining. i also get the oil changed at jiffyboom or whatever only when the dash tells me (so around 10k miles i think), and the only work it has needed engine wise is a water pump about a year ago and a set of coils and plugs about once a year (yes really). the best part? it has 188.5k miles right now, will hit 190k by may, and if it doesnt make it to at least 200k by new years it either blew up, crashed, or i was fired.
Get it tuned, man. Livernois Motorsports or any of the others and on 93 octane it'll make 400hp and like 500ft/lbs of torque and be just as reliable as ever. Even with stock everything else, I have the 2.7 in my Ford Edge which is heavier than an equal model truck, and it runs 12.9's on just a livernois tune on 93 octane. Would be even faster if it was RWD bias AWD instead of the FWD bias/haldex type AWD system it has. The F150s and up that have the 2.7 will run mid 12's all day on just a tune and maybe an exhaust/intake system. Crazy.
@@curlyfriesolaire8053 Bro, I would tune my ambulance if I could and these things have 250+ thousand miles. Lol. More power, better economy, more fun, and no one would ever really know.
The oil in the cylinder could have been a mechanic pouring a little in the plug hole for a compression test, testing if it's rings causing the low compression or something in the head...as we saw the burn't valve. Awesome vid Eric cheers mate!
Eric O. (South Main Auto channel) just showed the new borescope he bought that can swivel around once it's down in the cylinder so you can check out the valves without pulling anything other than the plugs. Used it to condemn a GM 2.0 turbo 4 in a Caddy.
I'm gonna give whoever gave you this engine the benefit of the doubt and hope that they scrapepd the turbos and didn't reuse them with there being metal in the oil.
2.7EB is incoming in the new Ranger (though maybe not until next year), so any info and look at the engine is welcome, even if it's well-known already! Thanks as always for the entertainment.
Keep the videos coming. Really enjoyed this one. I'm no longer an engine mechanic (was years ago late 70's early 80's era) and always like to watch your tear downs which help me keep up on current production engine tech and longevity which I love knowing about.
Belt driven oil pumps remind me of "sealed for life" transmissions (no dipstick and no way to check the condition) , of course they never specifically state what that lifespan is exactly so it basically boils down to it will last until it doesn't and then you're out 5-10k for a replacement engine or transmission.
I work at a high volume Ford dealer and since these engines came out we have changed one. We do 5.0L and 7.3L all the time. I own A 18 2.7L and absolutely love it!
I have the same engine and year F-150. I have 57,000 on it and run full synthetic , changing it every 5000 miles. I send in samples to Blackstone and the test results have been great. After two Ram 5.7 engines and Chevy 5.3, I still have reservations on small turbo engines. Considering what's available in new 1500 trucks with ice engines, I don't think any would consider to be a lot more dependable than the 2.7EB. 48:25 I love watching your teardown videos.
Indeed. Mine makes like 320awhp from just a tune(400+ at the crank) and has over 100k miles on it. 50k of those miles have been at the 400hp tune, running 12.9's and surprising GTIs, Hondas, SUVs, and Charger R/Ts when they get gapped by a grandma SUV(ford edge). I love these engines. They're so overengineered its ridiculous. Mine is Gen 1 so it has the chain on the oil pump, and every single thing I've ever had to do to it maintenance wise has been a pleasure. Ford built this engine to be maintained/worked on and you can tell.
@@BasedEMT1776 true. Personally I'm not sure what the big deal is over an oil pump belt. This is a low stress, short belt and it's doing nowhere as much as a timing belt. The belt will likely last as long as the engine itself, there are many 2nd gen 2.7 engines with over 200K. If you can get 250K+ out of this engine it really owes you nothing and if it needs rebuilt then do the oil pump belt as well. Easy as that. Mine's at 190K and I know Coyote engines also switched to an oil pump belt a few years ago. Then again no one is talking about having that belt go out. PS. Did you need to beef-up your transmission for the extra power? I thought the 6F55 used on the Edge was near its limit for torque (550Nm or around 405 ft-lbs?)
@@YoursInYeshua Livernois MyCalibrator handheld tuner, tunes by Livernois Motorsports. I bounce between the 87 octane tune and the 93 octane tune. The 87 octane tune is high 13's, mid 13's if it's cool out and 0-60 in the low 5's. 93 is 12's in the 1/4 and 0-60 in the 4's. It's even faster on E30 tune, but no E85 where I live sadly.
For 130K that engine was well maintained. It had to have gotten hot. The timing chain tensioner was melted too. Considering it had 130K on the engine and probably needed some more work (like the oil pump belt). I would consider replacing the engine rather than fixing. Depends on how nice the truck was.
The timing chain tensioner failed and put too much tension on the chain, causing the guide get hot and melt. Someone suspected this would have thrown valve timing off enough to eventually burn a valve. A bad injector may have caused it too but you would think you'd see wear on the bearings with that much gasoline washing down into the crankcase.
I have a 2.7 out of my 2018 with 118k sitting in my garage. Number 4 cylinder has zero compression. Got a replacement with 2300 miles for under 3k with turbos and they didn’t want my core. Eventually I’ll pull it apart.
My dear brother told me I ought to get one of these high-output engines - was not impressed when I told him "no way". I learned the lesson about reliability of highly stressed engines a long while back and bloody well did not buy one.
Good Lord! That's a pile of $$$. I think these engines would be fun in a hobby car, like a '69 Mustang. Not so much in a daily driver, high mileage situation.
Yeah what a shame the owner clearly took immaculate care, with short oil change intervals but parked it somewhere that collected a birds nest in the valley. He did the right things to keep it going for 200k+ miles and then got the rotten luck of a burnt valve.
My wife watched the first 10 minutes of thos video and then CHOSE to stick around to the end. She wanted to know how it ended and what Eric's diagnosis was. We also enjoyed the part where je turned the crank to show how things worked. 👌
I wanted to say I absolutely love your videos and I love that you used the borescope because I noticed the date which was filmed on my birthday. As always your videos are informative and common sense but yet you have a very entertaining way of driving home common Sense things that people don't understand when purchasing used auto parts.

@@JimBronson I’m shooting for 500K! 😁 I’ve got a little piston slap when it’s cold out, but it goes away pretty quick. I was an automotive machinist back in the day and I’ve worked on cars for over 50 years. I’m really amazed how well this thing still runs. It’s so quiet at idle that all you hear are the noisy fuel injectors clicking. 👍🏼
How often do you do the oil? I hear the 5.4 3v lasts a long time with 3k mile oil change intervals. Such short intervals don't let oil sludge up and block passageways, which then would kill the cam phasers.
Small displacement turbo charged engines that generate a lot of torque down low in the RPM range have a problem. They generate high cylinder pressures at low RPM to make torque. A high load at low RPM with high cylinder pressure is more prone to pre-ignition. A small carbon deposit on the valve could have been the source of the problem causing it to burn it. Using high octane fuel can help prevent the problem.
I have a 2019 2nd gen 2.7ecoboost F150. It has 84k miles, I turn the start stop off, last 2 years I hardly run my turboboost, mostly short rides in town. First three years It had alot of highway miles and that fun balls to the wall super boost use. I change oil with full synthetic every 10k. Have had no maintenance service. I did have an 02 sensor replaced. Any advice you guys? I want to baby it from now on, last truck I want to buy screw bidenomics. Do I need catch cans? Also I've had three cad converters replaced on the exhaust from the get go.
No need for catch can on ‘18 and up, it has both direct and port injection to keep valves clean. I change my oil at 2500-3000 mi, using a semi synthetic like ford recommends . I would recommend changing your oil now at 4000 mi max, all depends if you tow with it
28:30 ? Never mentioned again, i was waiting for an answer. I feel you owe me an answer, i can't see myself sleeping until i know. As always great video, with only two unanswered questions, why was the cylinder full of oil water, and WHY did that piston rock both ways on the wrist pin.
the piston wear would have been from all the unburned fuel washing the cylinder down and probably affect the wrist pin I would think? I was wondering about the coolant/oil mix in the other bank as well.
Surprised you didn’t further examine the piston with all the multi direction play in it. Be interested in knowing the condition of the wrist pin in that one.
A '68 Buick Gran Sport 350 I used to have had a burned exhaust valve in which I had a valve job done. The only thing I can figure out was that the exhaust manifold for that cylinder bank had a heat actuated spring valve to close the manifold to exhaust pipe to aid in warming up the engine sooner. The butterfly valve shaft had rusted shut which I tapped open since it was non functional anymore. Also the hydraulic valve flat tappets were dished with some that had worn holes in them. As I was very young at the time(not much money) I just cranked down the rocker arm adjustment nuts and made the engine a non hydraulic valve train. Worked for a couple more years. The engine was practically worn out with low compression.
The 2015-2017 2.7 did not have port injection, but it did use a chain for the oil pump. It was most definitely bean counters who made the decision to switch to a belt.
I know with the multiair engine, a local running the stock tune and 91 octane has burned a valve. I have raced my car its entire life but I’ve always run 94 octane fuel and for the last 4 years I’ve run water/methanol. Additionally, I take extra precaution to tune the engine where the fuel enrichment comes in gradually rather than all at once like the stock tune. I also use more fuel during WOT, rather than targeting 14.7:1.
2.7 has proven to be a very reliable engine. They hold around 500 wheel sustainably. They tend to blow when pushed beyond that. There are many 2.7’s approaching 400k.
@@snakehead5444 10r80’s hold a ton of power. From all the tuning groups I’m in it’s always engines that fail first before the trans/drivetrain go. The common failure on these set ups tends to be valve related failures when over 600 hp. There are people that have 2.7’s around 800hp. I’ve yet to hear about people building these engines out to survive long term at those power levels.
I feel your pain about the missing water pump. It may have been in excellent, re-usable condition and I know you would've been very, very careful with such a part.
"Oil pump drive belt" shouldn't even be a phrase that exists. Thanks car makers, for racing to the bottom....
I was shocked that GM chose a belt for oil pump on the 3.0 Duramax. I wonder if Isuzu had been the major on the 3.0 like they were(are?) on then6.6 Dmax, if a belt would have been used.

That melted chain guide kind of deserved further investigation too but it won't keep me up at night. 😄
Ha ha.
Had to be wear in the pin holes in the piston, given the pins are a seize fit in the rods....unless it wasn't a seize fit any more of course. Can't imagine how oil pressure would affect pin clearance?
But, yes, would be nice to have that investigated a bit more.
As soon as you said why would somebody take a water pump and reuse it. I thought well that the engine overheated. Because it had a bad water pump. They replaced it and then the engine died. So the water pump wasn't that old. So they took it and put it on the used engine. Now I'm making this, 20 minutes into the video I could be totally wrong I have been before. So if you are taking apart a good engine why don't you rebuild this one that'd be a treat for the channel.
Installing used pumps of any kind is a dumb liability for a shop. A "chain of custody" is more important than "saving a buck" if you are standing behind your work.
But do we have any proof that a shop did the work? At the age of 58 I retired and sold our 12 Bay body shop. I have seen a lot of weird things owners of cars and trucks have done.
@aregeebee201 head gaskets sometimes fail in a way you can't see it on them.
Probably replaced engine because that piston wrist pin wear was causing knock, and the ECU, thinking this was detonation, due to the timing on that cylinder, had pulled power way back. Then the lowered fuel input meant the cylinder was running ultra lean, and this, combined with probably a small carbon particle that got stuck on the valve, caused it to wear, and then the ECU carried on running that cylinder ultra lean, leading to the valve seat eroding as the combusting fuel mix kept on bleeding by. You can see the run marks of the metal being eroded away. Engine replaced because ECU told of misfire on one cylinder, bad knocking and lack of power, along with very lumpy idle. Compression test said cylinder really bad on leak test, so scrap engine instead of stripping head, because the used engine is cheaper than a strip, repair and assemble labour wise. Pump likely removed because it was faulty on the junkyard engine, probably leaking water, so to cut cost they swapped with the old one.
@@jamesgeorge4874 do you understand how ridiculous you should? If you buy a used vehicle do you replace every used pump of any kind? Educate the comment section on just how the water pump would be untrustworthy in the OP's theory, I dare you...FFS.

Question, was it Thanos or Agent Smith who thought they were a Subaru when it comes to Boxers and this channel...? 😅
I can't understand why they put so much resource and design in the casting, overly so IMHO, yet cheaped out on a fibre oil pump belt. But yet another great video, thanks Eric.
Because a bean counter did the comparasion, and the belt worked out to a few cents cheaper, plus it added 0.001MPG improvement in the standard test cell run.
So the engine would grenade.

I wouldn't wait on that oil pump belt service considering they start to shed debris that will clog up the oil pickup screen. If the previous owner short tripped the truck a lot, it will degrade much faster. They seem to break down faster due to exposure to unburned fuel in the engine oil.
@@hochhaulhave you torn down or repaired a lot of ecoboosts?
What year is your 2.7? I’m at 126k with my 2017.
@@hochhaul and there is no proof that they degrade faster with short trips and no proof that the belts shreds anything. Once again it could fall back to sloppy maintenance.
I have a collection of burnt exhaust valves on my "shelf of shame"... And every single one came from a stock engine with excessive oil consumption. Hard to say why this Ecoboost burned a valve. A bad injector would melt the piston long before a valve got torched 🤔
A turbo engine is like having a build in cutting torch....lol You can see the cutting lines on the valve like it was cut with a torch. Which it was by the turbo.
Honestly it was probably tuned and he got some bad gas. Detonation turned into a plasma cutter. Seen it before.
I don't remember if it was mentioned in any of the other 2.7 vids but the reason for the interesting block construction is because it's made from compacted graphite iron (cgi) which is significantly stronger than standard cast iron, it's the same type of iron that Nascar engine blocks are made from. It's really a shame other manufacturers haven't taken the plunge to invest in CGI blocks because it offers significant gains over standard cast iron.
Also, the coating on the bearings was introduced into Ford engines (and likely other brands too) when they made auto start-stop systems standard to increase MPG ratings. The coated bearings hold up much better to repeated frequent restarts than uncoated bearings.
Good to know. I can’t believe how good those bearings looked with nearly 140k.
What is the point of a cgi block and then fit a belt in oil - bad engineering!
but they use a wet belt, negating all benefits of those innovations
@@Nordic_Mechanic have you heard of any failing?
@@D3M0ify So what's wrong with a wet belt other than it's something none of us are used to seeing? Find us a wet belt 2.7L Ford that has blow up due to a failed wet belt. Crickets 🦗🦗
I work the service parts counter at a large Ford dealership and we would replace. It's faster to replace the engine than repair plus the customer gets a warranty. Aside from the oil pump belt and plastic oil pan, I think that Ford did a pretty good job with the 2.7L. I feel it is the least seen engine needing major repairs in the shop.
That's odd because I have a watched a couple of other videos of Ford mechanics where someone goes around and asked what motor they would buy and pretty much all them said the V8. I peryonoe 3 friends that have had there 2.7 "eco" boost motors blow up. One the dealer has to do two!
@@apwurst The 5.0L is also one of Ford's better engines. There is definitely less to break on the 5.0L plus you can't beat that V8 rumble. I think we have to understand though that Ford builds hundreds of thousands of engines every year so there will be a few with manufacturing defects.
@@doomspeaker1256 this is true. IF I wanted an F150, I'd go with the 5.0 just because I like the V8 burble/rumble. EcoBoost trucks don't have much of a voice out of the box.
Sadly the new 5.0 won't live any longer before needing torn down. They now use rubber bands to drive the oil pump also.
@@05milmachine90 lol wat? The 5.0 oil pump is driven off the crank proper, always has been.
Once i saw the valve, i would have stopped there...thanks for continuing on in the name of science!
That wear on the chain guide is from the tensioner failing and applying too much pressure, causing excessive heat.
Ah good reasoning...I was trying to figure that out and failed to so I thought I'd double check the comments nice thanks.
I'd put money on that being the original problem, causing enough friction & wear on the chain guides to screw up the timing just enough to cook that valve. Just wish we could've seen what caused the slop in that one cylinder. 🤷♂️

Your videos are great! I'm learning so much more about my Gen-1 2.7l EcoBoost Engine inside my 2017 Ford Fusion Sport than I ever will scouring random forums about my car.
I have a 2017 Ford Fusion Sport and had to have that engine (2.7l EcoBoost Gen 1) replaced because it blew a head gasket and leaked coolant into the cylinders, but based on your past breakdown videos on both the Gen 1 and 2 2.7l EcoBoost engines, I have a more complete understanding of what makes this engine tick. The replacement engine costed almost $5k including labor to replace, luckily I bought an extended warranty that covered everything bumper to bumper when I bought the car.
I bought this car second-hand off of Carvana, so I didn't know how this car was treated before me. I found out, after I bought the car, that the car had 1 quart oil low and there was no oil on the dipstick when I was getting an oil change, me being a buffoon and not knowing anything about my own engine at the time, ignored that warning sign. Six months later, my engine started consuming coolant and was emitting white smoke out the tail pipes, I was wondering if there was a leak or something, but I couldn't find a leak anywhere, come to find out the coolant was leaking into the cylinders.
One cold morning, I was accelerating hard on the on-ramp on to a freeway, a giant cloud of white smoke covered the freeway and my engine completely shut down. That was when I knew the head-gasket blew and coolant flooded my cylinders. I think the previous owner of this car neglected the car and the engine and let it overheat from oil starvation. My car was in the shop for 6-months, because 2-months was searching for a replacement engine. Apparently this engine is hard to find. The 2.7l v6 EcoBoost is a marvel of an engine, paired with an AWD drive-train in a four-door car makes for some fun driving. I'm also happy to know that the Gen 1 2.7l engines have chains for oil pumps, although it doesn't have both Port and Direct injection, I'm okay with that.
The replacement engine now gets an oil change every 3000 miles, I don't care about Ford's 5000 or 7000 mile recommendation. I'm not giving the replacement engine a chance to oil starve. The replacement engine is also now modified with a CAI, GFB+ Diverter Valve, and 93 gas tune. I've also upgraded the brake lines to Steeda Stainless Steel brake lines, I saw a manufacturer recall on how weak the front brake lines could be on this model and year car so I decided to upgrade all four brake lines to braided stainless steel. Keep your 2.7l and 3.0l Ecoboost videos coming. Your videos are super educational and you've got another subscriber!
I had a 2017 Lincoln MKX AWD with the Gen 1 2.7L turbo. It’s the same engine that is in your car and I agree it is a blast to drive and is a perfect match for a car that size and weight. It was probably OK in an F150 if treated very gingerly without any towing, but I would still have wanted a larger engine in a truck.
I’m retired so I don’t drive that many miles, but after reading about the issues with that engine; only direct injection, plastic oil pan gasket issues and other assorted moderately expensive maintenance necessary at 60K, I got out of it early. If I had a 2018 or later, I probably would have kept it a little longer, but there were still too many potential problems so it was best to move on before the repair and big maintenance bills hit all it once.
Don't be hard on yourself. It's most likely that your 2.7 had the dreaded long block defect that plagued something like 1 in 3 2.7s for a few months of 2016 manufacturing.
A supplier screwed up and delivered a batch of long blocks with uneven decks which caused the gaskets to eventually fail and leak coolant.
The 2.7 as a ford tech is my recommended engine from my anecdotal evidence and from other that have been around that place more than me. The 2.7 is the most reliable followed closely by the 3.5. they don't have manifolds so they don't have the warped manifold issues of the 3.5 they make less power so they aren't as stressed. But they also just don't fail. We tear down 5.0s all the time fro oil burning and the 3.5s for phaseres. The 2.7 has a slight issue but nowhere near as bad as the 5.0 or 3.5s. we've only done 1 2.7 and that's because of a faulty belt broke in the right way to snap off the oil pressure switch we've done a few 3.5s and way more 5.0s and the 5.0s are the least sold (I know the 2021 2.7s and up have valve shattering issues but I'm referring to gens 1 and 2)
Wasn't there a coolant issue with the ports getting clogged between the cylinder walls.
@@Bigfoothawk nope
We all feel your pain about not having a perfectly good water pump to shoot from the 3-point line...be strong; there'll be another one soon, I'm sure!
Everyone keeps complaining about the rubber oil pump belt, but it looked totally fine at that mileage. What about all the cam chain tensioner failures. Chains are so much better?
You need to change your oil every 5000 miles. Neglecting oil changes is what kills engines.
That's not true. They've known since the 60's that rubber and oil don't mix. I don't give af what "compound" Ford says they made these belts out of, they'll all crumble into oblivion before the 150k interval they claim it lasts. 50k miles and those belts are already swelling. Chains are infinitely better.
Let me emphasize that a dry belt system, totally fine. Key word, DRY.

UOA should drive OCI for the application. 3k, 5k, or 7.5k max. If you tow change it sooner, etc. A car isn't just an expensive toaster.
I just love the brilliant design of these engines. Plastic drain plug that always leaks, with the sway bar directly in front of the plug. Once you pull that plug, it gushes out like on a Subaru, hits the sway bar and goes EVERYWHERE
The drain plug leaks because people reuse them. They're a service item and you're suppose to use a new one every time. Ford tells you this in the maintenance manual. You can invest in aftermarket unit like the Ronin drain plug that converts it to an all metal design that has a smaller orifice to drain out of, but honestly once you drain it once you know not to just rip it out as fast as possible, and to hold it like he did. Or just hold the bucket RIGHT up to it, and let it drop in there after you crank it off, and replace it with a new one like ford said. No mess, no oil everywhere, and it drains in like .7 seconds. Lol.

Injector failure, or at least malfunction. Created a hot spot in the chamber, turbo keeps pumping in air, hot spot gets really lean from not enough fuel, boom-burnt valve.

And MOST of 5he time it does work perfectly. As he said there were missing parts so he could not tell what happened to this engine
Exactly, leaned out do to the injector malfunction and Mister Blow Torch fired up.
all that so called TeC, and burns valves like a 1962 dodge
I have heard the phrase "burnt valve" many times, never actually seen one. Thanks for that!
The burnt valve was radically burnt, looking like it was blasted with a gas axe. You'd think the computer crap would report a loss of compression in that cylinder.

I am happy that I just bought a three valve 5.4 liter 2009 Ford f150. The timing components and oil pump were changed shortly before I bought it for $1700. It still was having timing issues. I found the cam position sensor connection plug was bad. i was so happy. It is perfect now.
I was quoting a MX13 for a 2025 Kenworth T680 yesterday. Engine was $63,000 and the core was $8,000. The truck has 6k miles on it and was in a crash bad enough to break the block
The Cummins in our 2000s Freightliners run about 10k for a rebuild. They refuse to look at new motors cuz it's ridiculous.
This is why companies like mine buy wrecks. We salvage all sorts of shit from them and use it to rebuild others. We can build up a truck with 10k miles for $100k when a used one with miles like that is $275k+ easily. Saves so much money.
Wow
You need to remember that those blocks are graphite composites. Strong internally, weak when outside forces are inflicted on it. I hear they are now making sleeve kits for when you have to inframe the engine instead of purchasing a short block.

I came from the modify and maintain world and now have carried over the good habits of stock and maintain.
For my money, with the way the rest of the engine looks, especially the lack of damage to the rotating assembly, I'd fix this one, no doubt. With a replacement you wouldn't be able to check these components, therefore it's an unknown quantity. For the difference in cost, the peace of mind would be with it, but that's just me.

Every toyota I drove was loud and rough but I imagine reliable. If I'm watching Dave ramsey I will buy a toyota. If I'm not I will buy a ford.
@@spacebound1969 One evening in 2009, I met a Ford engine department engineer, so we talked about...engines. He said that the Toyota 4.0L V-6 (in my '06 Tacoma) was one that Ford BOUGHT to study. He also said that the crank angles were critical to making power. I'm sure he was right, but that V-6 was just mind-boggling with its flexibility and power. Mine was a 6 speed manual with towing gears. There was almost no situation where any of 3 gears wouldn't work fine. The one thing to avoid was going up a freeway onramp in 2nd gear, because it accelerated so hard in 2nd and finding 3rd wasn't to be rushed. MPG wasn't great, and was pretty much the same as its replacement, an '08 Silverado 4x4 with 5.3L. Range is better with the Silverado. There are some things I don't like about the 5.3L, but it's relatively simple. The complexity of the newest Ford engines pretty much makes them throw-aways, IMO. Would be fun to install in an older european car, like a Cortina or even BMW. I've driven a couple of BMW's and really liked them, but could never afford to own one. 😪
There is a more important reason why the piston rods are offset. It allows for better geometry in the position of the crank shaft and rod during the compression stroke.
Referencing your last 2.7 teardown if it was do to small displacement and high HP. Auto makers that make all of the high hp 4 cylinder engines would fail to based off that assumption, which is not true. There are alot of 2.7 ecoboost engines with high mileage. Its that old mentality mechanic that assumes that like scotty kilmer he will tell you to buy nothin but a naturally aspirated toyota from the 90s. Tech has changed so much over the years that is why i have the 2.7 and its been a great motor. Thanks for the videos 👍!
I have the big brother to this engine. The 3.0, in my explorer ST. I’ve had my engine tuned with FBOs and it makes about 520 hp at all four wheels. I did this at about 3000 miles. It has about 32,000 miles and the only mechanical problem I’ve had is a sensor with the all-wheel-drive system leaking.
The 10R60 transmission is another story.
These engines make amazing power. Turbos, fuel pump and a tune will get an explorer into the high tens.
The 3.0 v6 TT seems to be the Magic number for power. A lot of new manufactures are making a 3.0 i6 or v6 TT
You know what would have been a great April fools joke, is to tear down a good well maintained engine😂!! Happy Easter
Thanks for continuing to make such great videos, Eric.
the more i see of these 2.7's the more i like them. the coolant crossover tube in the back and clean valves from the port injection addition is really nice!
The first set of cam caps sounded really good during the cracking process. Perfect double click clacks lol
fwiw my work truck is also a 2018 2.7, and i use all 400 ftlbs that thing makes 5-6 days a week, 50-200+ miles a day. i drive that thing like its a racecar, pedal to the metal, if its not idling its redlining. i also get the oil changed at jiffyboom or whatever only when the dash tells me (so around 10k miles i think), and the only work it has needed engine wise is a water pump about a year ago and a set of coils and plugs about once a year (yes really). the best part?
it has 188.5k miles right now, will hit 190k by may, and if it doesnt make it to at least 200k by new years it either blew up, crashed, or i was fired.
Get it tuned, man. Livernois Motorsports or any of the others and on 93 octane it'll make 400hp and like 500ft/lbs of torque and be just as reliable as ever. Even with stock everything else, I have the 2.7 in my Ford Edge which is heavier than an equal model truck, and it runs 12.9's on just a livernois tune on 93 octane. Would be even faster if it was RWD bias AWD instead of the FWD bias/haldex type AWD system it has. The F150s and up that have the 2.7 will run mid 12's all day on just a tune and maybe an exhaust/intake system. Crazy.
@@BasedEMT1776 why would he tune a company truck.
@@curlyfriesolaire8053 Bro, I would tune my ambulance if I could and these things have 250+ thousand miles. Lol. More power, better economy, more fun, and no one would ever really know.
tell me your joking and that you trust jiffyBoom oil changes at 10k. I guess you'll wont make it to 300k at that pace.
The oil in the cylinder could have been a mechanic pouring a little in the plug hole for a compression test, testing if it's rings causing the low compression or something in the head...as we saw the burn't valve.
Awesome vid Eric cheers mate!
Eric O. (South Main Auto channel) just showed the new borescope he bought that can swivel around once it's down in the cylinder so you can check out the valves without pulling anything other than the plugs. Used it to condemn a GM 2.0 turbo 4 in a Caddy.
Would love to see a tear down of the 2.7 liter GM Turbo 4 cylinder in the 2019+ full size pickups.
I'm gonna give whoever gave you this engine the benefit of the doubt and hope that they scrapepd the turbos and didn't reuse them with there being metal in the oil.
The only thing about good ol' uncle rodney is, you can't hear him knocking if he's been evicted🤣🤣🤣🤣🤣
Nah, I think he payed his rent this time.
Eric, thank you so much for having such a valuable information channel.
This particular video on a 2.7 Ecoboost is what I was looking for.
👍🏼👍🏼👍🏼👍🏼👍🏼
2.7EB is incoming in the new Ranger (though maybe not until next year), so any info and look at the engine is welcome, even if it's well-known already! Thanks as always for the entertainment.
My 2.7EB ‘18 is at 165k. Have no fear, just change the oil with Ford oil.
Keep the videos coming. Really enjoyed this one. I'm no longer an engine mechanic (was years ago late 70's early 80's era) and always like to watch your tear downs which help me keep up on current production engine tech and longevity which I love knowing about.
Belt driven oil pumps remind me of "sealed for life" transmissions (no dipstick and no way to check the condition) , of course they never specifically state what that lifespan is exactly so it basically boils down to it will last until it doesn't and then you're out 5-10k for a replacement engine or transmission.
This channel has excellent balance of humor and technical data! Thanks man! Well done!
I haven't seen any 4.2 Trailblazer engines yet.
Which is good.....cuz my 2002 has 245 K on it
still runs like a top 🙂
Would love to see a Vortex 4200 teardown...just hope it isn't yours!
@@Trendyflute lol
you and I both 😏
My son has a 2005 Envoy XUV with the 4.2 Vortec. 200k and still going strong.
Our 4.2 has 327k on it.
That's because they get swapped into other Failblazers to keep those trucks on the road (until they fall apart, then the cycle starts again).
41:22 the red low friction coating on the rod bearings is mainly used in vehicles with the auto start/stop feature
Side to side rocking is worn out wrist pin. It’s toast.
Keep up the awesome teardown videos!! Educating and entertaining for sure
Come all from far and wide. Sit down, grab your favorite drink and enjoy a wonderful Saturday evening engine tear down with some dad jokes
Here here
And yeeted parts
but sorry, Water Pump couldn't make it here tonight 😭
Don't forget the melted timing chain guide and Kevlar oil pump drive belt questionable remaining service lives... Another great video.
I work at a high volume Ford dealer and since these engines came out we have changed one. We do 5.0L and 7.3L all the time. I own A 18 2.7L and absolutely love it!
Exactly my nephew has a 2015 with 177,000 miles on it runs perfect
Fantastic instructional video! Sometimes deconstructing something teaches more than putting it together! Thank you!
I can not decide if I like pop of the coil overs being pulled, or the crack of the headbolts being loosened.
Definitely the head bolts for me.
Head bolt crackage 🥰🎶🔧🔩
Coil pop
As long as it's not snap, crackle and pop.
Head bolt SMR
I have the same engine and year F-150. I have 57,000 on it and run full synthetic , changing it every 5000 miles. I send in samples to Blackstone and the test results have been great. After two Ram 5.7 engines and Chevy 5.3, I still have reservations on small turbo engines. Considering what's available in new 1500 trucks with ice engines, I don't think any would consider to be a lot more dependable than the 2.7EB.
48:25 I love watching your teardown videos.
Honestly, the 2.7 ecoboost is one of the better engines Ford had built recently. Just do your maintenance people 😉
This guy did and it blew up. Garbage.
Indeed. Mine makes like 320awhp from just a tune(400+ at the crank) and has over 100k miles on it. 50k of those miles have been at the 400hp tune, running 12.9's and surprising GTIs, Hondas, SUVs, and Charger R/Ts when they get gapped by a grandma SUV(ford edge). I love these engines. They're so overengineered its ridiculous. Mine is Gen 1 so it has the chain on the oil pump, and every single thing I've ever had to do to it maintenance wise has been a pleasure. Ford built this engine to be maintained/worked on and you can tell.
@@BasedEMT1776 true. Personally I'm not sure what the big deal is over an oil pump belt. This is a low stress, short belt and it's doing nowhere as much as a timing belt. The belt will likely last as long as the engine itself, there are many 2nd gen 2.7 engines with over 200K. If you can get 250K+ out of this engine it really owes you nothing and if it needs rebuilt then do the oil pump belt as well. Easy as that.
Mine's at 190K and I know Coyote engines also switched to an oil pump belt a few years ago. Then again no one is talking about having that belt go out.
PS. Did you need to beef-up your transmission for the extra power? I thought the 6F55 used on the Edge was near its limit for torque (550Nm or around 405 ft-lbs?)
@@BasedEMT1776what tune and tuner did you use?
@@YoursInYeshua Livernois MyCalibrator handheld tuner, tunes by Livernois Motorsports. I bounce between the 87 octane tune and the 93 octane tune. The 87 octane tune is high 13's, mid 13's if it's cool out and 0-60 in the low 5's. 93 is 12's in the 1/4 and 0-60 in the 4's. It's even faster on E30 tune, but no E85 where I live sadly.
For 130K that engine was well maintained. It had to have gotten hot. The timing chain tensioner was melted too. Considering it had 130K on the engine and probably needed some more work (like the oil pump belt). I would consider replacing the engine rather than fixing. Depends on how nice the truck was.
The timing chain tensioner failed and put too much tension on the chain, causing the guide get hot and melt. Someone suspected this would have thrown valve timing off enough to eventually burn a valve. A bad injector may have caused it too but you would think you'd see wear on the bearings with that much gasoline washing down into the crankcase.
I have a 2.7 out of my 2018 with 118k sitting in my garage. Number 4 cylinder has zero compression. Got a replacement with 2300 miles for under 3k with turbos and they didn’t want my core. Eventually I’ll pull it apart.
You got lucky with that price.
@@Foxbody302 They've got two more at that price with similar miles
@@AnonyMous-jf4lc good to know, thanks.
My dear brother told me I ought to get one of these high-output engines - was not impressed when I told him "no way". I learned the lesson about reliability of highly stressed engines a long while back and bloody well did not buy one.
Most people are tuned in watching Elite Eight. I’d much rather be watching this tear down video on a Saturday night!🔧
What's elite eight?
@@mediocreman2 🏀
I'll never get over just the sheer space that engine takes.
Looking on Pro Demand it calls for 17.5 hours to replace the oil pump drive belt. No real info on it other them replace the timing set while there.
I think in a front drive application it would be engine out
Good Lord! That's a pile of $$$. I think these engines would be fun in a hobby car, like a '69 Mustang. Not so much in a daily driver, high mileage situation.
@@StuntPosse 🙄
Great video on an impressive condition engjne for 131k. Have a Happy Easter Eric!
Yeah what a shame the owner clearly took immaculate care, with short oil change intervals but parked it somewhere that collected a birds nest in the valley. He did the right things to keep it going for 200k+ miles and then got the rotten luck of a burnt valve.
Hey dude! Scotty Kilmer mentioned you! He appreciates your work! So do I!
What video?!?!
I'd be embarrassed. Kilmer is an idiot.
Err, is that good?!
My wife watched the first 10 minutes of thos video and then CHOSE to stick around to the end. She wanted to know how it ended and what Eric's diagnosis was. We also enjoyed the part where je turned the crank to show how things worked. 👌
That drain plug reminds me of my craftsman lawn tractor engine's rapid evac. drain 😂😅
Man... It's relaxing and fascinating to sit back and watch a tinkering video before bed.
Why was the piston rocking side to side?! I dont need sleep, i need answers
I wanted to say I absolutely love your videos and I love that you used the borescope because I noticed the date which was filmed on my birthday. As always your videos are informative and common sense but yet you have a very entertaining way of driving home common Sense things that people don't understand when purchasing used auto parts. As always I love your videos and I don't know why but I had a really hard birthday but seeing the date definitely made my birthday seem a little bit better.
Happy belated bday my man! Agree with your comment on entertainment portion of the videos!
People are still driving 20 year old trucks? Not me! My truck won’t be 20 years old for several more months. It’s a 2005 F150 FX4 with that unreliable 5.4 3v. It had 25 miles on it when I bought it in early 2005 and it has 345k miles on it now. Had to rebuild the transmission a couple years back, but otherwise it’s original. Even the water pump. 😐 I’m towing my travel trailer around Arizona right now. Damn thing. 😎✌🏼
Cam phasers definitely
@@xinx-fn8973 They’re original. Engine has never been opened up. Replaced the throttle body long ago. Original starter, alternator, water pump and hoses. All original timing gear. I do all my own maintenance and have worked on cars since I was 13. I’m 69 now. It’s a great truck. Still gets the same gas mileage it always has. Has a little piston slap when it’s below forty degrees in the morning, but otherwise. 👍🏼
My 5.4 3V has 159k and needs phasers. It's coming soon. I've only owned it since 132K and it has a good life with me, i.e., frequent maintenance.
@@JimBronson I’m shooting for 500K! 😁
I’ve got a little piston slap when it’s cold out, but it goes away pretty quick. I was an automotive machinist back in the day and I’ve worked on cars for over 50 years. I’m really amazed how well this thing still runs. It’s so quiet at idle that all you hear are the noisy fuel injectors clicking. 👍🏼
How often do you do the oil? I hear the 5.4 3v lasts a long time with 3k mile oil change intervals. Such short intervals don't let oil sludge up and block passageways, which then would kill the cam phasers.
I could watch Eric doing this teardown all days.
Ok, how many of us were waiting for him to catch the cram cap bolt he missed trying to lift it off
I was yelling, "You missed one". But I am a day too late for him to hear me. Ted from down under.
I actually raised my voice when I saw it; my phone didn’t do its job and tell him though…
Small displacement turbo charged engines that generate a lot of torque down low in the RPM range have a problem. They generate high cylinder pressures at low RPM to make torque. A high load at low RPM with high cylinder pressure is more prone to pre-ignition. A small carbon deposit on the valve could have been the source of the problem causing it to burn it. Using high octane fuel can help prevent the problem.
I have a 2019 2nd gen 2.7ecoboost F150. It has 84k miles, I turn the start stop off, last 2 years I hardly run my turboboost, mostly short rides in town. First three years It had alot of highway miles and that fun balls to the wall super boost use. I change oil with full synthetic every 10k. Have had no maintenance service. I did have an 02 sensor replaced. Any advice you guys? I want to baby it from now on, last truck I want to buy screw bidenomics. Do I need catch cans? Also I've had three cad converters replaced on the exhaust from the get go.
No need for catch can on ‘18 and up, it has both direct and port injection to keep valves clean. I change my oil at 2500-3000 mi, using a semi synthetic like ford recommends . I would recommend changing your oil now at 4000 mi max, all depends if you tow with it
Love your analysis, skill, style, personality. Very informative and entertaining and pleasant to watch.
28:30 ? Never mentioned again, i was waiting for an answer. I feel you owe me an answer, i can't see myself sleeping until i know.
As always great video, with only two unanswered questions, why was the cylinder full of oil water, and WHY did that piston rock both ways on the wrist pin.
the piston wear would have been from all the unburned fuel washing the cylinder down and probably affect the wrist pin I would think? I was wondering about the coolant/oil mix in the other bank as well.
Always love the uncle Rodney jokes. This is the best TH-cam channel out there!
Surprised you didn’t further examine the piston with all the multi direction play in it. Be interested in knowing the condition of the wrist pin in that one.
A '68 Buick Gran Sport 350 I used to have had a burned exhaust valve in which I had a valve job done. The only thing I can figure out was that the exhaust manifold for that cylinder bank had a heat actuated spring valve to close the manifold to exhaust pipe to aid in warming up the engine sooner. The butterfly valve shaft had rusted shut which I tapped open since it was non functional anymore. Also the hydraulic valve flat tappets were dished with some that had worn holes in them. As I was very young at the time(not much money) I just cranked down the rocker arm adjustment nuts and made the engine a non hydraulic valve train. Worked for a couple more years. The engine was practically worn out with low compression.
The 2015-2017 2.7 did not have port injection, but it did use a chain for the oil pump. It was most definitely bean counters who made the decision to switch to a belt.
Interesting opinion
I know with the multiair engine, a local running the stock tune and 91 octane has burned a valve. I have raced my car its entire life but I’ve always run 94 octane fuel and for the last 4 years I’ve run water/methanol.
Additionally, I take extra precaution to tune the engine where the fuel enrichment comes in gradually rather than all at once like the stock tune. I also use more fuel during WOT, rather than targeting 14.7:1.
2.7 has proven to be a very reliable engine. They hold around 500 wheel sustainably. They tend to blow when pushed beyond that. There are many 2.7’s approaching 400k.
Sounds like a very underrated platform. I like the sounds of the tuning but how does the transmission hold up to another 100+hp?
@@snakehead5444 10r80’s hold a ton of power. From all the tuning groups I’m in it’s always engines that fail first before the trans/drivetrain go. The common failure on these set ups tends to be valve related failures when over 600 hp. There are people that have 2.7’s around 800hp. I’ve yet to hear about people building these engines out to survive long term at those power levels.
@@snakehead5444I work with a few people who own newer f150s and they are always driving dealership loaners, lol I love my Toyota
@@Turboboob Cause Ford fixes their fuck-ups for free. Toyota turbo in your future, Enjoy
I feel like those people getting to 400k got lucky. Ford did their wet belt treatment to the oil pump. Such a dumb design.
I feel your pain about the missing water pump. It may have been in excellent, re-usable condition and I know you would've been very, very careful with such a part.
