Hi, I'm new to this forum but I'm active on FSB and Race-dezert. I just bought a 85 ranger 4x4 that I'm building into a chase/prerunner machine. The engine has a wierd problem. I seem to be getting a popping noise (almost like an exhaust leak) but it's not from the exhaust. The truck is bone stock except the air pump is siezed and has no belt on it. I'm fairly sure it's leaking compression into the intake. I did a compression test and I got this:
1:125
2:130
3:125
4:120
5:125
6:110
It is possible I have a bad cam lobe? I'm going to pull the valve covers tonight and check that the rockers are moving visually. After that I'll disassemble the top end. Any ideas?
