    Still fighting oil leak

    So after pulling motor and tranny to replace the clutch and fix a bunch of oil leaks I have the car back together and running good. I still have one oil leak though. When it warms up oil burns off the exhaust manifold on the passenger side. The turbo is also covered in oil.

    I have replaced the valve cover gaskets, half moon plugs, round plugs, chain tensioner gasket and all cam seals.

    I dont feel any oil along the edge of the valve cover gasket. The rear half moon seal and round plug looks ok.

    The valve cover gasket on that side has the "V" that goes between the cam cap and chain tensioner. Maybe I did not get that in the groove? I did put RTV in the appropriate places.

    I hope it isnt coming from the turbo somewhere. This is a very frustrating car.

    did you use oem audi gaskets?
    if not, replace with oem
    also, did you use RTV at the corners of the valve covers and the 'V'?

    i did my VCG's 3 times before using oem, hasn't leaked since

    I did not use oem. I got a kit off Amazon. The valve covers are easy enough to get off. I'll give OEM a try.

    Looks like it leaking out of the half moon seals. Did you replace the cam chain tensioner gasket?

    The half moon seals and chain tensioner gaskets were replaced and the RTV was put in the appropriate places on all gaskets.

    One thing I noticed when putting it back together is that the end cap for the exhaust cams had no gaskets or RTV. They are a metal on metal seal. Maybe I scratched the surface and its seeping out from there. The oil leak is right in that area.

    I looked up OEM valve cover gaskets. $80 a side? Wow. The Mahle ones are $40 a side. What brand have other people had luck with other than OEM?

    It took me a couple tries to get all the leaks on my S6 when I did it. I'd recommend making sure all the metal surfaces are perfectly clean - I even used rubbing alcohol. Then use a thin layer of Permatex Ultra Black on all seals. My main issues were the cam caps not seating/sealing properly.
