Review on 🔧 PCV Crankcase Vent Valve Breather Hose Kit for Audi & Volkswagen - Compatible with 2.0L Turbo A3 8P, A5 B8, Q5, Golf GTI MK5, MK6, Jetta, Tiguan - Replaces 06H103495AH, 06H103495AC, 06H103495E by Jim Polacek

I have decided to replace the PCV due to oil buildup in the air intake. After installing it, my problems got worse. It looks like the gasket/gasket on my top cap has blown resulting in a massive oil leak and vacuum leak. I was given the code P300. I replaced the gasket and o-ring on the cam/CVT and put the original PCV back in place. The oil leak stopped, there were no more misfires. It may have been an accident or maybe a faulty PCV. The replacement hoses are a bit fiddly to connect. A bit disappointed because I have used ignition coils from this manufacturer with good results.
