There should be an 8 stamped on the head if its 8-1. It appears that two things are going on. The first is a possible head gasket failure between the cylinder ( # 3 is quite a bit lower than the rest) and two, the rings are failing, thats why your compression jumps up so much during the wet test. I do believe.1969 Series 2a BugeyeComment
