      HPFP maybe on TFSI EA113, where HPFP is driven by tappet. On EA888 it is driven by roller. Water pump housing should leak, but it can easily run over 200.000kms from factory.
      Everything is resolvable, but one big issue on this engine is balance shafts, and oil screens, which can lead to oil starvation. Perfect maintenance is mandatory on this cars!

      @penismightier4303 2 місяці тому

      ​@@jonosvlog9913 The quickest way to tell is if it still to see if the engine cover has FSI or TSI stamped on it :) But they are also completely different shapes. If the engine cover is big and square(ish) with the intake plumbing coming into and under the cover from the lower right and exiting from the upper left corner near the MAF connector (viewed from front), it's the FSI EA113 engine. If the cover is smaller and rectangular with the intake plumbing running visibly up the side and across the back of the engine cover, it's the TSI EA888.
      If the car doesn't have an engine cover, I think the biggest obvious visual difference will be the dipstick location. If it's on the side of the engine (same position as the one in this video), it's a TSI EA888. If it's on the front of the engine towards the centre, it's an FSI EA113.

Not the strongest stage 2 but good enough for our shitty roads (Egypt) I've had a bad timing tensioner and got it replaced like 3 years ago and haven't had a single issue since (Except for a loose ground cable :D) Considering a big turbo build however not sure if I should buy a secondary car first maybe an R32

    Bought my MK6 in late 2019, about a year and a half into owning it, started noticing oil spots wherever I went. Turns out the rear main seal had blown out, bc of the PCV. $1500, mostly due to labor to drop the tranny. Glad I got it done, but for those if you who own/want to own a MK6, use this as a cautionary tale. Love my car, and for the most part hasn't given any other problems (had to replace the water pump about a year ago)

    I had to get a seal fixed because oil was leaking into the cylinder on the far right. Part was like 40 bucks but the job was like 1200 because the design VW went with on the MK6 had the camshaft being supported in a cheap way and had to be moved. They had to take apart half the engine just to get to the part. It's really not been any huge issues though. I'm at 110k miles and needed a clutch, fuel pump and master cylinder. I bought it brand new and I still enjoy driving it everyday. I do wish I would have got the 4 door version though. Next time....

    The diverter valve should also be updated(if it hasn't already) and I recommend looking into a dv+ from gofastbits.
    I'd pull out the sound deadening from the front fenders or at least remove the bottom portion. It gets soaked with water and will stay wet for a week. Removing the wheel well cover to do that will also give you a chance to clean that area thoroughly and then coat it with graphene or ceramic to prevent rust.
    I plan to have the car for a long time so I researched the hell out of everything. I enjoy working on it and love the car.

    Timing chains, yes, big problem on MKVI GTI’s. BUT I think the 2 biggest problems are the extended engine oil drain intervals, people not checking their oil level, and people not using VW Spec oil. It’s not just VW’s that consume oil, my Acura does too. Most cars do. You have to check and top off the oil in these cars, like you said, weekly! Once your oil level light comes on, it’s too late. It’s already shortened the lifespan of your GTI engine. It’s not good for your engine to be running with correct oil level and then low and then correct and then low, etc etc. Love your videos man. I own a MKII Tiguan SE 2.0T R-line Black Edition and have had an MKV GTI DSG and MKVI Jetta GLI 6MT. I see you’re from Massachusetts, I grew up in Brookline, MA, right outside Boston.

I’d blame the previous owner and possibly the current one too. However, my other friend with a mk6 gti, has been the worst. He drives this like an old lady, does maintenance or repairs immediately, and that thing just stays on the brink of catastrophic failure. I’ve talked to many other mk6 and mk4 owners and my general consensus is that mk4 has the better engine by far while the mk6 has a lot less issues with interior and electrical bs. Mk6 was my dream but my mk4 has treated me the best and with the insane potential of that 1.8, I’m glad I got the one that is legitimately faster than the kids with their “Cobb stage 2” tuned hatchback assortment.

    2013 VW GTI Wolfsburg Edition at Stage 2 with a little over 115,000+ miles. For the carbon cleaning, you'll know when because it sounds as if the engine is choking to death. Lots of misfiring and very rough idling. Had to do a clean-up last year along with my PCV replacement and diverter valve going bad.
    Also the timing chain tensioner could be a 2008-2012 issue. From what I've gathered, Audi/VW upgraded it 2013 and beyond.

    My dad did an engine overhaul 2 years ago and the DSG overhaul roughly a year ago. But ever since those major overhauls, the EPC and check engine light kept popping up, the water pump cracked, the ECU shorted out and there were a few times the car actually died as we drove above 12mph. Is there an explanation to this? Not sure if the mechanics ripped us off or didn't know what they were doing but I hope this isn't the end for the car.

  • @gilernt
    @gilernt 11 місяців тому +1

    I feel like people give our Mk6s a bad rap sometimes; I got mine at 150k miles and I'm over 215k miles now. I do both city and highway commuting, as well as daily driving and also leaving it to sit for weeks. I've had a good chunk of the common problems that cars with high mileage have (brake rotors, wheel bearings, serpentine belt, coolant reservoir stuff, electronics here and there, etc.), but the only real "catastrophic" things that've gone bad were my starter and water pump (separate events) both at around 200k miles. I definitely have not kept the car in amazing shape since I'm a broke, busy college student. For example, there have been a few times where I've run the engine ~10k+ miles without an oil change, I've driven a little while the temp gauge was past max, I race the car, I live in the NE so the winter salt definitely doesn't help the car when i don't wash the car for over a year, etc. All this and the car still runs smooth as can be and, fingers crossed, will continue to last me for a bit longer. In addition, I did the typical GTI Stage 2 engine mods (diverter valve, intake, full exhaust, tune, etc.) relatively early in my time of owning it and even with more boost and more things to go wrong, it's still kicking.

  • @wolfaja755
    @wolfaja755 3 місяці тому +1

    Just keep up with maintenance is really the bottom line. Do walnut blasting on your valves, so the timing chain, change your oil and all your filters, service your transmission, and a lot more. Your timing chain you should change every 50k miles in all honesty but if you modify it you need to do it more often because you’ll make more power and stretch the chain quicker. Oil changes I’d recommend every 5k miles but when you modify it, especially with a bigger turbo, drop it down a thousand or so. Your transmission it really depends. If you’re running a dsg you can get away with 40-50k miles unless if you modify it then you need to do it sooner. For a manual you need to assess the way you drive. If you do a lot of city driving or are on the throttle a lot you need to service it every 20-30k miles. Your clutch in your manual will eventually go out but that also depends on how you drive it. My original clutch latest 140k miles before it started to slip. A more aggressive clutch will require you to swap it out quicker. There are solutions for the carbon build up on the valves. One is walnut blasting which if not done right can absolutely kill your engine. That really only happens if the guy doing it accidentally sprays into the cylinder through an open valve. What I like to do is run an aux fuel system. I can make 600hp without running out of fueling now and it’s injected before the valves so it cleans them. Something not talked about is the water pump. It’ll fail and it’ll be a pain to replace. Mine died at 145k miles and I replaced it with a metal one. The water pump typically fails due to it cracking and not due to the actual pump breaking so a metal one is a go to fix. If you replace the intake manifold go with an aftermarket one. Even if you don’t want to modify your car it’s a way better option since it’s metal and most of them don’t have flaps in them. If you go with a bigger turbo get one that can fit in the oem spot ie one in a k03 or k04 housing that way all the oil lines hook up to it and your ecu can read it. Also if you want to make more than 400 horsepower you need more fueling ie aux fuel kits or wmi, you’ll also need something bigger than a k04 like a gt3071r. If you want to go above 450 horsepower you need to do rods, rod bearings and probably pistons. When you make more power you also want to step down to a thinner oil something like 5w-30 would work but you don’t necessarily need to do that since liqui moly makes good anti friction additives for their oil. The fly wheel will go out. Sometimes it warns you sometimes it doesn’t. This is an issue with both the dsg and manual transmission. The flywheel is a dual mass flywheel and it’s used because there is inherently a lot of vibrations and sharp impulses in an inline 4 engine along with the weak synchros that vw loves to put into their transmission. The two masses move relative to each other to take up slack and reduce vibrations making your weak synchros not die. Your flywheel can fail in a a couple different ways. First the springs could give out allowing the secondary mass to rotate freely to its max angles and this will sound like a helicopter is taking off under your car. When it does this it’ll slam into your transmission housing and you’ll have a bad time. Second the flywheel springs won’t fail but the clearances between the masses can shrink during hard uses causing them to bind together. This won’t make a noise however it’ll slowly destroy your synchros causing bits of synchro to destroy your transmission. Eventually you’ll transmission will lock up and you’ll need to replace it. An indicator for this is a slow but growing whine of your transmission. At this point you should either rebuilt your transmission or replace it because damage has already occurred and it’ll worsen on its own. The flywheel in this instance will hit your transmission housing although not as much as it would if the springs were the thing that killed it. NEVER REPLACE YOUR DUAL MASS FLYWHEEL WITH A SINGLE MASS FLYWHEEL UNLESS IF YOUR STRENGTHEN THE INTERNALS OF YOUR TRANSMISSION!!! The engines produced by vw have clearances between the cylinder and piston rings. These are there to allow oil between the piston rings and cylinder wall which lowers friction aiding in higher gas mileage and lower emissions. As your car ages these clearances will get bigger as the piston rings wear which means you burn more oil. Check your oil every time you put gas in your car. The lower the friction you can get with your oil the better for maintaining these clearances small. That being said use oils certified by vw. I recommend liqui moly. My car has only ever seen liqui moly after the first oil change and the condition of the engine based off of data taken while it was running and doing pulls is equivalent to one with 40-50k miles on it and mine has three times the miles. There is so much more for keeping your car running good but this is the major things. You do these and you’re not going to run into many major issues over the life of the car.

    Carbon build up depends how you drive. If you don't do any highway driving and you aren't driving at 3k rpm for long periods of time you probably will need to clean it every 25,000.
    I just did mine and once you get used to it it is easy. I replaced the old manifold with what turned out to be a brand new defective manifold so I was fortunate to have to pull the intake off 3 times in as many weeks. It took that long to chase down the error code. You just don't think a new part will be the culprit.

    I have 145k miles on mine and I wouldn't say that it's been more or less reliable than anything else I've owned. Yeah it's needed some repairs, but nothing beyond what I would expect of literally any car with nearly 150k miles on it.
    Something important to note is that the timing chain wearing out is not a problem that's unique to this engine. Even Honda's K series engines need new timing chains at roughly the same frequency as the TSI.

    I don't mean to trash your favorite oil brand, but liquid moly is a below average performer. Amsoil makes a vw spec euro 5w-40 that will easily last to 5k and I'd recommend you looking into it.

      I’m really happy with liquimoly molygen 5w40 I’m not even sure what amsoil is or if you can get it in the states

    Real main seal will leak. Replace it with iabed rear main seal after market part. Much beefier solution to prevent future leaks.

    From my experience: the intake manifold fails because of bad quality and/or low octane fuel, after the replacement (at 35K miles) I used only 91 octane from Shell and so far it runs smooth, now 104K miles on my 2013 GTI.

    just had my intake manifold on my EA888 in my tiguan 16, mine got stuck and it was causing a misfire in two cylinders, thankfully VW replaced it for free.
