2003 Audi S8 with this code
16839 - EVAP System
P0455 - 35-00 - Large Leak Detected

Do you guys think that a leak at the cam tensioners gasket would throw that code?

I have been pulling my hair out looking for the source of leak only short of using a smoke system to find the leak. I changed out the N80 purge valve, all the small vacuum lines, new gas cap, checked evap canister connection but comes up empty until using a bike pump and soap water to find the leaks which is at the cam tensioner gaskets with a glove over the intake to seal the system.
