"Well after alot of reading and picking the way i wanted to go to find out the problem. Here it is. Got an injector adapter for compression test made at local machine shop. Tested the compression....# 1 = 360 psi, #2=355psi and #3=210psi. Bingo, found the problem. Now i will do a leak down test to confirm the rings or valves or head gasket.

So, any sugestion on what type of rings to replace the poss bad ones with. I heard about chrome are these type normal instal from factory.

Also, any tricks to get the head off the block

Thanks,
Jonathan"
