This is only on EA113 engines. EA888 engines do not have a valve cover to speak of, it's a combination cover and bridge/girdle. On EA113 engines you are correct, a bad PCV will most likely blow out the valve cover gasket--a relatively cheap and easy fix. On EA888 engines a bad PCV is more likely to blow out the rear main seal, a relatively complicated and expensive fix (if you are paying someone to do it).Careful to determine that this is not just a valve cover leaking. This is a common occurrence due to failed PCV causing undue vapor pressure causing other gaskets to fail such as the valve cover, pcv, vacuum pump, rear main seal. This was my experience. The cam girdle gasket is expected to be more durable that the ones I mentioned.
Ahhh I think you can do it--I believe in you! Only thing is if you have winter where you are, like ****ty Canada, it might be a bit annoying to do even more so if you don't have a garage to do it in.That $1750 is just for that work, to replace the seals at the timeing chain cover and the cam girdle from Audi. VW told me $1450, but they need the car to make sure that's what it is. I know there is some labor involved, moving coolant reservoir out of the way, oil dipstick, coilpacks, PCV, HPFP and others. I've watched the YouTube hack videos on this and also have the official Audi workshop manual, thanks to a forum member. Not out of my league, but pushing the limits of waht I want to do.
Haha on EA888 Gen1/2? No such luck. VAG designed one of the worst timing chain systems evar. Granted they are not the only ones that has messed up a chain system. First of all the earlier tensioner (from when the engine started appearing in ~08 to sometime in 2012) that thing is a time bomb and is honestly the stupidest design you can imagine. Most (but probably not all) 2013 cars would have the newer tensioner though. However even after that the chain wears prematurely as well (some people call this "stretch"), meaning they also revised the chain but I don't think that happened until sometime in 2014. So even if you don't have to do a timing job because of the moronic version of the tensioner, you'll still likely need to do a timing job anyway.What's involved in a timing chain job anyway? I thought chains did not need to be replaced typically.
Yeah that's like 170k km right there. If the engine has never had a timing job, it's the time to do it TBH. If you gotta do the other stuff you might as well do the chain, esp. if you're looking at madness like $1500 just to do gaskets.103,500 miles on the odo. Got my 105k service coming up.
It's quite involved I would say, there's videos on YT if you want to have a look/get an idea. It's not impossible but if you don't have the time/space/tools, it might be better left to having done by a good shop. One of the worst parts will likely still be that engine mount and supporting/jacking up the engine to get it out. You also need the insert thing that prevents the crank from going out of time when you remove the bolt--that's critically important. The kits do include all the timing parts but won't include any tools you might need; also there may be fasteners (bolts) that are called out to replace that aren't in there either. For example the engine mount bolts are TTY, so you'll need to replace those for sure; possibly others.Thanks. I'll get a quote for a timing chain job. That may be over my skill level. What's involved in that work?
I like that there are complete service kits available: Audi A3 Quattro 2.0T Timing Chain Kits - ECS Tuning
