I have a 59 CJ5 with the F134 engine. Anybody know what the cylinder compression should be? I've got the jeep running again after sitting about 5 years and it's blowing light grey smoke. A lot of it. I've cleaned the gas tank, oil pan, added new ignition components, etc. Am trying to figure out if it's rings, head gasket, fuel, or what, and I need the numbers for decent engine compression. Thanks in advance!
