Does anyone know what the stock compression readings should be on a
1996 z28 Camaro with an LT1? My readings are as follows:
1=190
2=190
3=190
4=240
5=195
6=190
7=190
8=190
Cylinder 3 had been missing and I am replacing all the springs and will probably replace the valve seals as well, but I am wondering if anyone knows A) if these readings are within spec and B) why cylinder 4 has such high compression. Carbon buildup on the piston? Any thoughts would be greatly appreciated. Thanks,
