How a Small Failure Caused Catastrophic Destruction! - 6.7 Engine Teardown

[@supergrendel]

I'm fascinated that the same people who can afford to buy these trucks can neglect them to this capacity. Unbelievable really.

[@freddyramirez1820]

On credit you mean?

[@jasond1648]

They must listen to ford technicians and think they can go 10k between oil changes.

[@MrAnthonyfym]

They make money when they move. I have certain customers that only bring thier work trucks on rainy days

[@ajdest85UNC]

You're right that neglect causes a lot of these failures... Also BS ENGINEERING AND PARTS that just aren't made to last. All these variable cam timing engines are in theory if oil changes are done every 3-5k... And on and on... But all these tiny orifices that oil has to travel through and lifters that operate 2 pushrods .... Stop trying to fix something that isnt broke.I mean auto manufacturers not Dave's shop or any other shop.

[@nickd.4512]

They apparently have enough money that they don't care how much it costs to repair. Must be nice. Myself, the newest vehicle i drive is an 01 expedition 5.4 2v. As new as I'm willing to go. I can still fix most things in my driveway. Too time consuming and it goes to my ford tech who opened his own shop after working for a ford dealer for 30 years. And he's honest, doesnt charge outrageous prices or "fix" things that doit need it.

[@InsideOfMyOwnMind]

"That's probably why you don't have a shop." Brutal but true.

[@codo7]

I went to school to study diesel in 1977, we were taught if there were a catastrophic failure a motor needed to be disassembled and cleaned - the way you do at your shop, not just a wipe-down after spraying with solvent. A catastrophic failure is destruction of parts like we see on those rollers.

[@seagullsbtn]

Dave, I love the way you are showcasing more employees every video. They're the team, and your team has tons of experience and knowledge. Nice.

[@jonkeau5155]

When I had my transmission replaced I had them also do the rear main on the engine. They only charged me the price of the seal. The fact is that if you’ve got things as far apart as this on that engine you might as well replace all the wear items, the parts are cheap and you already paid the labor to get there.

[@seanstephens3896]

I feel for this guy, I went through the exact same issue on my used 2014 6.7. Carfax looked great, but it wasn’t until the engine was out Ford needed the block casting numbers for the warranty we realized it was a used 2012 block. Carfax won’t show shadetree mechanics. Of course I went to a “friend” and shop owner who replaced with a new Ford long block. Honestly paid more for that than going through Dave. I stumbled on Dave’s KZbin after the fact or else being 30 miles North I would have taken my truck to him. Everything has a manufactured defect, in this case the extended oil changes suggested is that manufactured defect. They can’t keep making money if nothing breaks.

I just recently discovered my 2014 F250 6.7 rocker arms fell off the intake valves on cylinders 1,2,3, &4. Lots of fun.

[@stevenbrooks1243]

Looks like lack of oil changes from all that sludge in the pan

[@gouldnj]

So many auto KZbinrs don’t show shit, half-ass things for failure content and don’t have any true value. You and your shop are different Dave and I would like to say thank you.

Planned obsolescence describes the practice of designing products to break quickly or become obsolete in the short to mid-term

[@Outdoorsy368]

Planned obsolescence is shameful. That to me is sub human garbage. Is that how the ones that come up with that crap want the products they buy to be built? Totally shameful

It’s sad. But ALLOT of companies are doing this now in many different ways. Auto industry was among the biggest offenders

[@halleffect1]

crazy how modern engines with roller lifters have so many cam wear problems. how in the world did flat tappet cams last past 100k?

[@v12alpine]

Flat tappets can go 500k+. Probably switched to rollers to avoid the mandatory 30-min breakin process and issues that can go along with that,

If there is one thing I have learned from watching this channel is do not buy a modern diesel unless its a must for work and you are putting the truck to work on a daily basis.

[@gordonv2456]

businesses idle the crap out of their vehicles and they say don't do it.

[@ar2043]

Hahahaha!!! You tell 'em Dave @ 8:15 and beyond for a few!! A lot of people, even some mechanically smart people, just don't get how important it is to tear it completely down and start from fresh once you have had metal debris flying through the engine.!!! CRITICAL!!! I used to run into the same problem with people who didn't want to spend the money way back in the day on their two-stroke PWC. Same thing. They have a failure of some sort, burn it down, you can see the head and top of the piston has been bouncing pieces of the piston ring all over the place and they want you to just blow it out and put it back together. (you know what I'm saying) No way!! Also, at this point in the game, most of Dave's customers know the type of work they do. Yeah, you can get it done a lot cheaper at many different places, but you are not getting the quality and attention to detail that you're getting at Dave's with him, and just as importantly, the WHOLE CREW. If I was in his area and needed something done that I couldn't handle, I'd be willing to be part of his clientele because I know what I want and that's that. If anybody thinks that Dave is selling people things they don't need, pay the fee for the analysis and then take it somewhere else. Guaranteed it won't be as good. Rock on everybody at Dave's Auto in Centerville Utah. 🇺🇸🇺🇸🦅🦅

oil changes ??

[@kevhauser]

Oh yeah..oil looks almost new!

[@lucluc2716]

Always wise words from dave! Love what you do man!

[@sounboy4498]

That more seems like an oiling concern. Lack of oil changes

[@RonRussell-sj1zf]

One of those funky 4 rockers/4push tubes per cylinder engines. Watched a video recently about installing a Jesel conversion to 2 rocker/2 push tubes per cylinder, which is the way I would go if it were mine. (which it would never be, as I couldn't afford to repair it) By the way, nice comeback on the "why did you put a motor in it" group: "that's probably why you don't have a shop!" Love it!

[@chipps1066]

A diesel engine is the last thing on Earth you want to half ass.

[@crazeddiesel]

The more I watch this channel the more I think of how it would be nice if every shop was the same way. I can tell that any tech that works here leaves with a ton of knowledge that they didn’t have before.

Another neglected engine, was not maintained to high standards. But followed good enough advice

[@Kebekwoodcraft7375]

Better no customer than a mad customer 😊

[@SyNergy81]

Definitely makes sense to me to pay more to make sure the engine is all set rather than a bandaid only to have future issues and have it tore down again because if the same original related issue. Thx

[@miketyler4536]

Dave how would you know about the lifter failure by just doing an oil analysis?

[@edwardhegarty750]

He said you would see a high chromium content in the oil.

[@garyharrington5300]

We've had 3 6.7s go down in the fleet ,it was determined that the driver had changed the oil and used 15 40w ,expensive lesson for shure

[@Sunspot-19]

[@arthouston7361]

If I wasn't running my own company, I'd take a week off and come and work as an assistant in your shop. I left auto and truck repair with 4 Master certs in 2000 to go and fly jets. Sometimes, I miss doing what you do.

[@thewatchersofthewood3530]

Almost ALL sellers do not want t let you do an oil test. They barely want to let you inspect the vehicle. Terrible and so hard to find honest sellers now. 😢

[@Amarillobymorning777]

Was designed to fail😊 No question about it

[@johnharris7191]

It may be really expensive but when they get their vehicle back the engine is almost as good as new.

[@rigell2764]

It will be better than new. Have you seen the quality of engines coming out in the past few years?

[@erickrosito3659]

Great detective work on cause of failure. What’s the cost difference between a full rebuild and to do a rebuilt ir bee long block repair?

[@82randyacman]

Can’t wait to get my light from yall

[@joebaucom4537]

Great !

[@oceanmariner]

There's gotta be more to it. Like low oil pressure, intermittent oil supply, collapsing oil filter, maybe an oil gallery restriction. It's not common to have several lifters with excessive wear and it's not common to have multiple cam lobes with excessive wear. Along with main and rod bearings showing signs of trying to spin. Bearings spin because of contact. But with oil pressure rod and main journals never touch their bearing, instead riding on an oil film maintained by pressure. Maybe the maintenance wasn't good and when noise started, the engine got a couple quick oil changes making the sludge situation look better. Old Marine Diesel Rebuilder

At 8 minutes 50 Dave is making gravy for his roast dinner😀

[@Mr.J345]

Hey Dave have you torn down a 7.3 Godzilla yet?

[@dorianleclair7390]

Looks like lack of maintenance. That oil was filthy. Extended oil changes are not ideal.

[@tvtonite79]

I understand about the oil analysis & agree, but what if they change the oil & don't drive it. Many dealerships/car lots do that. Would it still show up?

[@Joseph-xe3kz]

Bet you it was blow by. Hole in the piston. 6.7 power stroke. They don’t work on any other motors

[@ppump24valve53]

They work on n rebuild everything

[@dsstaang]

They actually do more Cummins than anything.

[@budlanctot3060]

Dave, for the edges of the roller to get worn down like that, it looks like the lifter roller is wobbling like a bad caster wheel on a shopping cart. Are the lifter trays allowing that, AFTER the roller bearing needles are beginning to fail?

[@Lawnfella]

How many miles on it?

[@deanmeyer1815]

He said about 200,000 in the video.

[@martinharper5112]

Thank You Dave. Much appreciate the offer of winning a motorbike. Questions. It's probably going spend more sending to the UK? And...I aint got a motorbike license either? Hope the person who wins appreciates the ride... M

[@FarmerTom-bz6tn]

Curious what type maintenance intervals this engine had and what weight /type of oil used. In addition would be interesting to know if this engine got plugged in during cooler/cold weather to bring oil up to temp prior to driving. Did owner use 15w40 full synthetic oil?

[@loluspololus]

To many camshafts lifters problems lately on chevy ford dodge engines

[@PeterMacGrergor]

Great decision.

[@winch1587]

What I don't understand is why US (V) engines still use pushrods, while most, if not all European and Japanese engines use overhead cams. Much simpler, with more options for cam timing.

[@fredgompper4925]

That's not oil in that pan its sludge going for road tar!!

Im only here for the flashlight & some sauce or summat

good thing they saved all that money from oil changes to buy another engine...

[@David-yy7lb]

That is the worst rocker assembly I've ever seen in an engine...hey wait a minute after watching the video to the end the 6.7 uses two push rods per lifter to open both exhaust valves and intakes valves instead of a bridge to open both the intake and exhaust valves so that explains why the rocker assembly is so cluttered.....WTF Dave you need to open a shop here on the east coast to

[@budlanctot3060]

I'm surprised that delicate looking spring is in a diesel hydraulic lifter.

[@dc6233]

On top of this failure diagnosis, was it the 200K plus miles on this particular motor that it's just wore out? or did the owner not use a quality engine oil, or was the oil not changed enough??

[@ModMyMind]

Manufacturer recommended 10k mile oil changes strikes again.

[@michaelbegay9573]

All of the engineers at the big three are looking and saying "that's what's happens?"

[@showtimemyles9643]

So one worn lobe on a cam and we should replace engine or rebuild? My dealer just replaces cam and lifters. Asking for learning purposes

[@kennethbrown8723]

Where do you think the metal from the worn cam lobe goes? It’s now through out the engine everywhere oil goes!

[@matt45540]

It's the cost of getting to it, once you get to a certain mileage and if you don't catch it early enough by doing oil tests it's not worth it. If you're 30,000 mi and you somehow heard it and caught it early sure but 200,000 is too far, just rebuild it If you plan on keeping it

[@cliffmorgan31]

Dumping out the oil pan after saying people who think, he's just selling engines. Ouch.

[@arthouston7361]

Those last few moments showing the mains where the bearings spun suggests an align boring is needed. Yes, that is a lot of money that needs to be spent, but let's not forget that there are two aspects to this. One is the lack of maintenance, and the other is insufficient design engineering.

[@KennethMyers-i2t]

That looks look like a piss poor design for a lifter you could even run a Honda motor with that kind of lifter

[@garyjarvis2730]

Bet someone beat the engine to death - didn't change the oil, used cheap oil and crappy filters. Taking the time to do routine maintenance with quality components is no secret but is the recipe for long drivetrain life.

[@JT-qf4it]

Total lack of maintenance! This is totally the fault of the owner. Oil changes were not performed when they should have been and possibly using the cheapest oil he could find.

[@cowboy3490]

that has to be the dumbest design for a lifter.

[@cliffmorgan31]

Poor preventive maintenance and LACK of systematic regular oil changes cause serious engine problems which commonly are blamed on the engine manufacturer by the guilty owner. “Not my fault”…. Manufacturers are certainly not perfect, but they certainly receive more blame than they deserve.
