Hey Frank, I hear you are the Head Expert.
I have a Head Crack question,.. 2002 ALH TDI. I am doing a new head gasket, sent the head out to get surfaced and found one chamber had a hairline crack from the injector, to the intake valve. Is this a 'replace the head' or 'run it' scenario? Been searching and a few have said that it's not a prob and run it. I would appreciate your input.
