Good morning all, Well as the title states. After a tune up on my newly purchased 2005 1.8T, I have continued getting the Cylinder #2 misfires as well as other codes including the O2 sensor. I'm at work and don't have the exact CEL's on me right now. After a few days of research and getting some advice, it seems to all lead back to an internal head gasket leak or possibly the head being warped/cracked. The car is my daily driver and was purchased 2 months before this issue arose. I did buy the car because it was in a great shape and for the 120K miles it had on it with auto/4-motion I decided to pick it up for the 5K. So I do want to invest the money/time into it to keep it for more than a few years if possible. Well after a few weeks of looking for a head just in case if that was the issue, I could not seem to find a direct swap AWM head anywhere. After hearing from of few members here an there I was told it has been harder an harder to find certain parts, manifolds etc. Well I came across a member selling an AEB head which I was told it is a "big port head" as to small port which is my AWM I have now. I am a long time VW guy but this is my first 1.8T standard motor car. So my 1st question of the million I have is..has anyone done this head swap? I do hope it is as least possible for the $500 I have spent on it. As of now I am in the process of talking with Integrated Engineering about how to fit the intake manifold spacer, from what they say is that I have to modify my coolant pipe a bit to fit it on the AWM. Well thanks for taking the few minutes to read this guys and any help would be great on this subject!!
