Audi tts piston recommendation
Hello all, sorry for the long post! I’ll try and keep it as short as possible without going too in-depth. If you want more info or have any questions let me know. I’ll start with a list of mods that way all info is provided, the turbo was on it when I bought it, the rest I installed.
2011 Audi tts, mileage just under 95,000
Apr stage 3 w/tte420 turbo
Apr carbon fiber intake
Apr oil catchcan
KW V1 coilovers
3” down pipe with Milltek exhaust
I’m looking for recommendations on new pistons dealer wants $3000 for OEM, the cars not worth it to me to dump that kind of money into the engine. I don't keep cars for long so I’m looking to keep the cost around $1000 for parts, if possible.
I don’t want to sell or trade in the car knowing the next owner is going to get screwed like I did if it’s not fixed. I’ve owned the car for a year, bought it from a dealer so I have no idea of what services have been performed other than what the CARFAX has provided.
I have issues with it burning oil, noticed it not long after I bought it. I’m guessing that’s why the previous owner dumped it. What I do know after some digging, APR confirmed it has a stage 3 tune with a tte420 turbo that was done in October 2020.
I’ve spent many hours researching, inspecting/testing the engine to conclude it’s the piston rings causing the issue. I know some people say the TTS wasn’t one of the cars that were affected by the 2009-2011 oil consumption issue and it’s the turbo that’s bad but, I’m 99% sure mine is the rings. After scoping the cylinders 1,3,4 had a lot of carbon build-up and when I would crank the engine by hand I would see oil running down the cylinder walls, the reason I replaced the valve seals. Cylinder 2 is fine, with no carbon or oil.
Below is the list of what I’ve done to try and correct the issue.
Mileage when I bought the car
85,675
Current mileage just under
95,000
Compression/leak down test all good, I will add numbers later.
New valve cover.
Removed PCV block off plate that was installed when I bought it.
Install Apr (pos) oil catch can.
Remove catch can, reinstall stock PCV to test crank blow by.
Valve stem seals.
New rear breather tube (the one with the check valve).
Inspected turbo for shaft play, it has no more than what TTE claims is normal.
Inspected intercooler for oil, none present.
Replaced turbo oil drain line.
if I missed something I need to check please let me know.
