Golf R Blown up Engine Teardown!

We bought a MK7 Golf R with 246,000 miles on it! This car was sold to us for $2,500 dollars because the engine was blown up. In our last episode, we ripped the engine out of the car, and made a step by step process so you could follow along! Now we are ready to teardown this engine.

[@almaadams3631]

​@@Enzo187How much bottom end would need to be "built"? Rods?

[@basedemt6608]

Don't ever put a turbo on your good engine that came off of an engine that ate a bearing or had metal in it. Regardless of mileage. The turbo has just become a super effectively anti-seize manufacturing pump, that will pump forbidden glitter all in the new engine. Don't do it. Mileage honestly is less important. If it's got no shaft play, and it ain't smoking...use that SOB. As long as it ain't got glitter production capabilities.

[@mitchell9937]

Can you not clean or rebuild these turbos? Flush the lines, spray some carb cleaner through it, and blow it out with an air hose and it'd be fine. Even better, run it through an ultrasonic cleaner first or just take it apart. Obviously I wouldn't want a 240k mile turbo on a rebuilt engine but I don't see any reason to throw it away either if it's not actually broken.

[@basedemt6608]

​@@mitchell9937 You can, but problem is the internals. It can marr the surfaces of the bearings, or stick in places that you just wouldn't ever be able to reach, and loosen itself overtime. Not being condescending, I mean this as a science project, buy a used/bad turbo and stick a boroscope up through the oil drain portion and have a look around. There are so many places to hide crud and metal that flushing alone will never get. An Ultrasonic cleaner might do the job. Problem is, you'd have to fully disassemble it, which is a big deal if you've never actually done it. You have to mark everything, including where the nut sits on the compressor so not to unbalance anything. Then let's say at this point okay, you did it, the turbo is 150% clean. You still have damaged thrust bearings from abrasive materials being circulated at high pressure, and damaged journal bearings that the shaft rides on as well, which WILL shorten life drastically. If you rebuild it, it'll need to be rebalanced as an assembly. Easier honestly just to buy a good used turbo that's not been contaminated and save yourself the trouble.

[@mitchell9937]

@@basedemt6608 I don't disagree. I'd buy a new turbo too. Even if it didn't have metal shavings in it, I'd be surprised if it was good to reinstall after 240k miles. I still wouldn't throw it away without even looking at it though. Maybe new turbos are completely different than the 20+ year old ones I'm used to, but it's not hard to take them apart and take proper measurements. I can buy a rebuild kit for $80 and rebuild mine in a weekend. Beats $600 for a new one, because I don't care about my time.

[@basedemt6608]

@@mitchell9937 Agreed. I come from the DSM world and despite what people may think about DSMs or Mitsubishi as a car company, their heavy industries build some of the most reliable and robust turbos around. I have zero problem using a 240k mile 14B from a 91 Eclipse GSX as long as it's not metal contaminated. If it has issues, I can rebuild it like you mentioned for like $80 just marking the nuts. To answer your question: new turbos and new technology in general suck. Everything these days is made with almost planned obsolescence in mind. (everything here being slightly exaggerated, but vast majority is no exaggeration).

[@bobp3738]

My Mk 6 Golf R had a catastrophic failure at 84K miles of the tappet on the fuel pump piston (not uncommon, I learned), broken pieces of which were flung around inside and actually broke through the aluminum housings. It was impressive. Taking apart the top of the engine, I discovered several bolts had been installed with blue LocTite, which caused them to become stripped or break off in the head and block as I attempted removal. Not fun. The previous owner had it Stage 2 tuned with several APR kit parts, which I knew and definitely enjoyed the extra ponies, but the installer evidently thought LocTite was a good idea. I thoroughly enjoy your channel and content. Thanks for doing it!

[@einfelder8262]

Catastrophic failure caused by APR tune. That's why VW won't warranty engine failure caused by aftermarket mods. Extra pressure from the APR fuel pump.

[@MrTheHillfolk]

​@@einfelder8262 Figured I'd do a little copypasta from the google thing. APR Plus, a performance engine software for new Volkswagen vehicles, comes with a limited powertrain warranty. The warranty is valid for five years or 60,000 miles and also includes roadside assistance. The APR Plus warranty is similar to a factory limited powertrain warranty and has the same term limit as the original vehicle warranty. APR Plus is available through Volkswagen dealerships and can be financed when purchasing a vehicle. It can be used with all APR...bla bla bla ....

[@almaadams3631]

TSFI engines had that failure prone high pressure fuel pump. I think most guys replaced the whole thing or at least part of it when they tuned the mk6 R. The reason I would not buy the Mk6 R ( bought a 2013 GTI, it has been great. Water pump and intake manifold replaced for free.)

Entertaining and informative... Par for the course with Pauly D. Recommendation for you Paul... Harbor Freight "Hardy" Nitrile 9 Mil (black) work gloves. Super durable and if you buy the size down from what you'd normally wear (I normally wore XL gloves but use the L sized gloves) you don't have all that excess glove material to contend with when you're trying to grab stuff. Because they're thicker than what you're using, they last a lot longer. I use them with different solvents and I can get 3-5 uses out of them before I need to grab a new pair.

[@Deutscheautoparts]

Thanks for the recommendation. I have some Nitrile gloves for when I need them, but I hate nitrile bc its not stretchy.

[@craigiefconcert6493]

This seems like the moral is also don’t fire the parts cannon: diagnose. If they found the burnt valve with a leak down test they would have saved all the money they spent on injectors and saved the engine.

Man I've 2003 XC90 at 327.000 kilometres, bought at 240k. It still runs fine, I did ask my shop to do good maintenance on injectors etc. It feels better than it did at 240k. Meanwhile My '09 passat variant's TSI engine was death at like 150k. I learned that less complicated engines live a lot more and costs much less. Even my old '99 Carisma GDI engine lasted more than TSI of Passat. First GDI engines ever

[@GhostYT_lat]

I have an 04 XC90. I bought at 115k miles and now it's at 174k. It's the 2.5t and It runs amazing. I've had two coils go bad and last time one went bad I replaced all the plugs as well.

3:12 I've had this happen a couple times with my tools. The M12 drill goes in to party mode when one of the 3 secondary contacts on the battery doesn't make a good connection with the drill. It just happens with those batteries from time to time. The drill goes, "oh no, I can't read the thermal sensor on the battery! For safety reasons, I'm just not going to work." The Solution is to look inside the drill to see which contact it uses, and then gently bend the contact on the battery out just slightly with a small screwdriver or something. Then you should be good to go again.

[@markooska]

Drove on a idle misfire fault for a year, fixed it. Sometimes I get a code for that same cylinder. Probably scraped my piston rings🥲

[@rkan2]

Cylinders needs to be pretty badly scored to give misfire codes imo. I bet more of a valve sealing issue.. Valve seat or the valve itself.

[@RS-vu3df]

19.13 No, I think you got it wrong. The misfires (e.g. faulty plug or coil) will damage the valve. Unburned mixture will ignite when in contact with the hot exhaust gasses of the neighbour, the back thrown plasma will damage the surface and it leaks. etc etc. There is however no connection between the bearing damage and the valve damage.

[@Vizqa]

Amazing work

[@AnwarZafar]

Despite the vehicle's impressive mileage of 240,000 kilometers and a seemingly solid build quality, catastrophic failure of all big end bearings while the main journal bearings remained intact indicates an underlying issue unrelated to parts or workmanship. The oil supply system between the main journal and big end bearing oil ports is likely the culprit. Based on my experience, this type of failure is often caused by debris, such as chunks of oil filter paper, blocking the oil supply passages to the big end bearings. This could be attributed to a low-quality oil filter, poor oil quality, or a slight drop in oil pressure that specifically affected the big end bearings

[@rbiddy5893]

I had a 2015 GTI in 2015 that I bought with 30,000km. It always seemed to have a misfire and an uneven idle intermittently. It was under warranty so in the 8 months I had it, the dealer had it for 4, just throwing parts at it and it was never fixed. We have no lemon laws in Canada so I finally convinced the dealer to buy it back but now I wonder after seeing this if it had a burnt valve. Either way I was glad to be rid of it and bought a brand new 2016 GTI which was great and I enjoyed for 5 years
