I can help you these are misfire faults , can i ask why you replaced the crankcase breather valve did you have a system too lean fault ??

Customer: replied 10 months ago.
Right, random multiple misfire, Cyl # 1 and Cyl # 4,, in OBD2 is P0300, P0301 and P0304,,I just replace to be safe, I hear this valve became bad and is very common and not I never have a system to lean fault.

Have you checked the rear main seal and did you remove the carbon off the intake valves when the intake was off ??

Customer: replied 10 months ago.
I don't have oil leak in the rear main seal off curse I clean the carbon in the intake, any other clue???
Expert:  vwtech0405 replied 10 months ago.

not the carbon off the intake but the intake build up on the intake valves since this CCTA motor has a lot of issues causing this type of concern
