[@elcaminomant]

We've replaced 3 of these engines in the last two years in our small VAG only shop. 2 locked up solid, 1 let rods out in spectacular fashion, but they all had seized rod bearings. Rods out had 42k miles, bought new, never tuned. First seized had 152k miles, dual pulley with tuning. In the end we traced all 3 back to the HPFPs leaking gasoline into the engine oil. We pay very close attention to the smell of the oil when doing oil changes on these engines now.

Great video...again. I also have a CCBA 3.0T in my 2012 S4. It's modified: dual pulley, exhaust, Ultracharger, Stage 2++. It ran awesome...up until 118k miles (oil change every 5k) and ALL bearings seized BAD. All the mains and rods are cooked. I was on my way to a show when all of a sudden it stopped. No lights, no drama, just coasted to the side of the road. I am now building a high HP engine. I would like to see you do a timing chain job on this engine (if not done already). Thanks for the great content: 1.8T, 2.0, and now 3.0T

Germans they always make this overcomplicated rubbish so that then they charge an arm and a leg when something goes bad.

[@richardberryhill718]

Perhaps the best teardown I’ve seen. Nice and thorough, good video throughout with narration, and step by step job. My bet is on the leaking of gasoline into the oil. That would certainly do the work showing on this one.The whole engine seems like engineering gone wild with over-complications. Exactly what I thought of my 1979 BMW 530 and wife’s 1978 320: they just kept adding parts and systems to accomplish the job, but no one ever said “OK, now let’s see how simple we can make it.” I hated working on both those cars and have never seen anything like them before or since. No more of them for either wife or I.

[@robpeabo509]

Great teardown & commentary Charles. The crank and the lower con-rods certainly got very hot due to oil starvation. the discolouration and blackness is both burnt oil staining & evidence of very hot steel. The bearings & bearing material that looked welded to the crank also supports the starvation hypothesis.

[@klubstompers]

I would place money on crap oil viscosity from fuel or water intrusion. If your low on oil, your going to get a nice flashy light on the dash, and start to hear some tapin.

[@deadprivacy]

In another commnet the hpfp leaks fuel intot the oil. Wrecking its viscosisty and those pcv valves also leak coolant in.

I have this engine in my Q…I’m not a DIY guy at all, so thank you for showing me what COULD go wrong in my car…maintenance is the ticket to longevity! I will also add that there is not a service I can think of other than a car wash that doesn’t cost 1000 dollars or more (way more) on this Q7!

[@goclunker]

Sell that turd and run

[@TassieLorenzo]

@@richardwilliams9181 What regular maintenance (aside from the obvious oil changes) would be suggested for this particular engine and at what intervals? High pressure fuel pump? Injectors? Coils? Seals? Timing chains? Would it be worth replacing the high pressure fuel pump and injectors every 90,000 miles? It seems the PCV is an issue too, what would the maintenance interval on that be, 60,000 miles? Unfortunately a lot of this maintenance is not actually in the service schedule I think, so it is up to owner's to schedule this maintenance.

[@richardwilliams9181]

@@TassieLorenzo Tbh, I don't have much experience or knowledge on Audi services. My only suggestion is check all fluids regularly. And it's at the discretion of whoever is doing the check whether the fluids would need changed. And the only reason I'd say the fuel pump would need to be replaced is if there is an issue related to it. Like hard starting, running rough, or not staying running very long. Typically any kind of engine that has a cam actuated high pressure fuel pump is going to have a reduced service life of the timing components because of the extra force the pump puts on it. And all services are also dependant on how much driving or what kind of driving you do. Do you drive it from your house to the store every day? Or do you have to drive hours on the highway for work? Do you spend a lot of time idling in traffic or at a job site? The shorter distance trips usually have less of an impact on the life of fluids, but can have an adverse effect, especially with engine oil, if the engine hasn't had time to warm up to temp. Long distance constant speed trips are almost ideal for fluid life. But things like engine oil, trans. fluid/diff fluid will have a reduced life. And constant low speed start/stops with a lot of idle time is arguably the hardest on any fluid or parts. Because with no cool air moving through the radiator or around parts, it generates a lot of heat. Which breaks down the fluids and related parts faster. Again, I'm no Audi specialist by no means. But it shouldn't be too hard for an experienced technician to know upon visual inspection whether a fluid should be replaced or not. Some parts can be tricky to diagnose without first having to remove and inspect. Which some parts on some vehicles can be a few hours of work just to get to a simple part. And then there's having proper equipment to do a proper diagnosis. The equipment you have is essential to making a good diagnosis. You can have all the knowledge in the world on how to fix a car. But if you don't have the equipment to get the information you need to make a proper diagnosis, it makes it very hard to get by on educated guesses. It doesn't pay to have to keep guessing at what the problem is. Then it gives you the dreaded title of "parts hanger". Just throwing parts at it until it's fixed. Most of the time, the parts you replace would have needed to be changed anyway. But if it doesn't fix the problem you set out to fix, it doesn't look good for whoever is doing the work

Very cool to see my engine apart and why I should do regular oil changes. Don't want anything to do with timing or engine internals. Car is 2014 S4. I did have a bad PVC that decided that the engine needed coolant in oil. That was fun.

@@bobsy852 yes. If you ever have the coolant disappearing. Check oil cap to see if looks like a milk shake. There are plenty of KZbin videos and how to in forums. Think the best one is from FCP Euro. Pretty straight forward. But after I fixed it I got a true coolant leak. Took me some time to figure the cross pipe broke while I was working on PVC. Car it's running like a champ.

And it's a shame when people just abuse engines like that it's obvious that the person who owned it didn't take good care of it. That's a shame but Thank you for the video

[@bl4cklne]

Never heard or seen anything like this on a 3.0. I bought a S4 with a broken valve on cylinder 6. Thanks to God no damage to the cylinderwall. Restored the valves and did anything needed to be done. Timingchain isnt that big of a deal itself, just follow the instructions, but you need some special tools which sucks big time. Good Video :)

I just got a 2013 Q7 with the 3.0T - same issue suspected on exhaust valve. Did you have to pull the engine to get the head off? Do you want to sell any of those specialty tools?! :)

[@Inimbrium]

Hi. I have a problem with this engine in my S5. If I rev it over 5k it starts "burping" in a similar fashion as it does when you change gear, but constantly. If I keep revving, it loses power, doesn't respond to throttle and goes to idle vibrating weirdly meanwhile the EPC and Engine Light come on. I have to shift into neutral, stop the engine and restart it for it to work again. Anyone know what it might be? I've asked around in shops and nobody knows what it is. I use premium gasoline fuel.

These engines stock had Oil starvation issues, so anything you upgraded or tuned on them is only going to make that more of a pressure point on the engine it self. Invest in better cooling and oil pump.....Edit. I just finished the rest of the video lol and you went over it being upgraded and the oil starvation issues, awesome video as always

All boils down to who's doing the work. This wouldn't have cost much in parts (if you just throw new bearings and rings in it) and machining (assuming that there are no cracks or warped blocks etc from the heat) and being able to reuse the pistons, cams etc.... Might have needed a new crank though. But those hours of labour at shop rates add up real quick.

There is a mechanic here in Poland that talked about this engine , I think it's this one, from newer models. He discovered that engine has some valve electronically controlled that decrease oil pressure when engine is idling! Basically it's running "dry" .So in long run (100 + thousand km) engine deteriorate and seize up ... Basically it's designed to fail ....

[@WallyG-ju6kx]

Would love to see a timing chain video. Hard to imagine this could be done with engine in place. Great content on all your videos. Keep up the fine work.

[@ronchampagne8484]

Boy I can't wait to run out and buy one of these gems . For the CBFA owner who has thought he's seen everything. Thanks for the heads up !

[@vaughan2203]

I watched all 24 minutes of this and I don't even own an Audi of this age. In fact, I own a 2018 Tiguan. I just appreciate the hell techs go through to address the problems they encounter, and what the conversations must be like with neglectful owners (I'm assuming) who then want to haggle about the price of a repair such as this.

[@milodemoray]

Thanks for this teardown video. It is good to see all the nightmare results of not taking care of your car. That is also an impressive, intricate engine.

[@leonardwapi3988]

Seized engine looks so clean.

[@rileytavares4087]

You’re a whole genius when you sit next to any motor/engine and do this!! I’ve always wondered, do cool geniuses like you ever think of building their own engine ?

[@SibRevs]

We need more tear down videos. This is awesome.

[@MrBlunt32]

Love breakdowns like this and seeing the problem in order to remove the mystery

[@christophermarshall5765]

That crank is toast. I would not even think about rebuilding that engine. Like you said my friend, cheapest option is to replace the engine with a new one.

[@ScooterTraveler]

This was so interesting and educational to watch. Amazing what damage can happen when the engine is not lubricated properly. Stumbled upon your channel by way of one of your shorts. I'm a new subscriber now. I look forward to binge-watching your videos.

[@TheEvertw]

Awesomeo teardown. Amazed at the level of damage, I'd have thought the cylinders would seize before the rod bearings do...

[@AcuraLvR82]

Literally once you got inside the motor especially the dirty crankcase, I knew it would be one of the last rods seizing it up. Just dealt with it myself on a customer motor it also seized the last rod due to low on oil. It seems when oil levels get too low its usually the very last rod that seizes first because it the farthest away from the oil pump. In his case once I unbolted the culprit rod, the whole thing including rod bolts came right all apart. He not only seized it up from low oil, but he tried several times to clutch drop going downhill it to start it again (manual acura integra) and I think that action stretched the rod drastically.

[@philipfarnam6013]

Excellent/clear video. MUCH better than most. Thanks for posting.

[@HumbleMechanic]

Thank you

[@chriseastburn3551]

I was a journeyman engine mech in my past life. Worked on some complicated engines. The 3.0T is very complex. Not for the inexperienced mechanic. Very interesting vid. Oil starvation fer shur

[@stanislavczebinski994]

Who ever owned this thing most probably tanked it ice-cold - pedal to the metal. Just because you can buy something doesn't mean you understand it. The carbon sud usually builds up by doing a lot short-distance driving. TFSI engines are more prone to that due to DI. Carbon build-up on older engines get constantly flushed away. The super-tiny oil holes in the super-tiny piston rings (for saving a ridiculously small amount of fuel) are also prone to coking. Here in Germany many engine-pros put the pistons on a lathe and enlarge the grooves for fitting proper piston rings. The small stock intercooler on an upgraded turbo engine does no damage - you just lose a few horses.

Working at a friend's shop we had one come in where the cat was plugged up solid on 1 bank. Replaced the cat and did an oil change test drove it. Customer picked it up and 1 mile down the road seized up. Crank to block. Took 20 min of a sledgehammer to remove the crank from the block. After a full tear down of course.

[@mikemcmanus887]

That was super fun to watch and ur commentary is mostly very easy to grasp for a newb

[@ziminarblaze9670]

It is hilarious to listen to you at 2x speed. But this is genuinely very interesting to see an engine be pulled apart

[@HumbleMechanic]

Lol I’ll have to try it

[@tylerwoods8713]

Gotta love when you do a timing job on this you just do a rear main seal. This gotta be one of the most non DIY friendly motors I've seen in a while. good ol audi

[@rcoolwind]

At our shop, Audi/VW products constantly need engines. Not sure if Kia/Hyundai is worse but at least most of them are covered under warranty. I see so many of my customers buy used A4s and the engines are constantly a problem in every area from timing issues to burning so much oil. We do at least one 2.0 timing job a week

[@Inimbrium]

Hi. I have a problem with this engine in my S5. If I rev it over 5k it starts "burping" in a similar fashion as it does when you change gear, but constantly. If I keep revving, it loses power, doesn't respond to throttle and goes to idle vibrating weirdly meanwhile the EPC and Engine Light come on. I have to shift into neutral, stop the engine and restart it for it to work again. Anyone know what it might be? I've asked around in shops and nobody knows what it is. I use premium gasoline fuel.

[@kevinhufford1064]

I have recently ran across an A7 with 197k miles for a fantastic price. After seeing some comments here, it's probably not worth it. It is a gorgeous vehicle and I have spent over a week thinking about it.

[@double-you5130]

it's trully amasing watching an expert work. thank you. jolly good show 8)

[@CaptianInternet]

10:24 - Despite the crazy work behind the 9 gears synchronized by 4 chains I get to a point where I am really really excited. Becasue any moment there must be a "oohhhhh this fucked up everything moment". Great content!

[@scott6828]

Absolutely fascinating lesson!! I've always wanted to see what an engine looked like when ran w/o oil....and one w/ too much.

[@tylerwightman2315]

Those are great motors when properly maintained. Bought mine years ago with 35,000 miles. Currently at 240,000 miles and doesnt skip a beat. Ive always changed the oil religiously every 3500-4000 miles with 5w-40 full synthetic. It has had a few leaks over the years that ive fixed but nothing too serious that I wasnt able to do in the driveway on a Saturday. Other than that, been very good to me and I love it. Wouldnt think twice about driving it coast to coast still.

[@Robert-un3cf]

That's probably exactly the problem with the engine he's tearing down here. They bought the 10K+ oil change meme cause oil is "so much more advanced now!" and now we see the resulting carbon, varnish, sludge... This is what happens.

[@blewyd]

Bar seems to be set pretty low for audis engines in the past few decades.

[@rdallas81]

My 2004 Dodge Hemi has over 300,000 on it. Everything original besides filters, oil, axles, brakes. Have a 2004 v6 4.2 F150. Also has 300,000 original miles. Replaced battery, starter, water pump, thermostat, radiator, tires. Both trucks need ball joints soon, also tie rod ends. Had a 1997 Chevy Cavalier 2.2 with 400,000 miles on it- And a 1988 Honda accord with over 1 million miles. I replaced the clutch in that Honda. 4th clutch.

[@tylerwightman2315]

@blewyd dang bro, you rack up the miles! Haha 1 million miles on an accord is impressive. My first car in high school was an old 91 beater accord. Bought it with 420,000 all original drive train however the engine developed a bad rod knock just before hitting 500k. Rebuilt it myself and drove it a little while longer before selling it. Aside from my Audi with 240,000 mentioned in my original post, My 2002 F250 7.3 diesel is at 376,000 as of now with no major work, my wife's 2010 Volkswagen Touareg is just about to hit 200k and it's never needed a single thing done to it aside from routine maintenance. Also had a 98 silverado 5.7 vortec that made it to about 350,000 before it started crapping out all over the place. Folks don't realize how long a vehicle can last with proper maintenance.

[@ploek]

Holy moly. That thing must have been glowing red

[@MonstertruckBadass]

I don't do anything with any kind of engines but this was extremely interesting to watch!

[@GSRIDER57]

Please, Please do a timing chain video for this engine. I have two cars with this motor, both nearing 100k and plan to do both chains myself. Love your work! Thanks.

[@some______guy]

I've never seen this channel before. I really like this guy.

[@HumbleMechanic]

THANKS!

[@Jake-if3zn]

When you pulled the oil pump, it looked like it got hot. From what I could see, the oil pump failed and the con rod bearings and seizing were the fallout of a failed oil pump. *Pay close attention to the oil pump at 11:16. You'll see the discoloration
