I have a 1992 j175glenc compression on two is 90 two are 85 one at 70 and one at 60. I decarbed it did not help. So I pulled the port side head no scaring on the cyl an I can see that the top ring is not stuck real clean it has a oring type head gasket How do you tell if it is blown? what else would cause the problem beside ring wear I can see the end gap on the rings and it appears to be even amount with the two other cyl's that are 85 and 90. Any idea's???
