First let me preface this by saying that I am at best a very amateur mechanic so I apologize if my terminology is incorrect and my question hard to follow.
I have a 1968 Mustang with the original 200ci 6 cylinder motor. The problem I am having is that I have very little compression on 3 of the cylinders and the other 3 are fine. Numbers 3 4 and 5 are the low ones and 1 2 and 6 are good. So of course the engine won't idle and runs very rough when given a lot of gas.
I thought that for sure it was a bad head gasket so I pulled the head. But the gasket looks fine. As does everything else. No visible cracks or holes anywhere. Everything moves appropriately when I manually turn it.
I am hoping someone may be able to shed some insight into what the problem may be because I am completely stumped. What could cause me to have no compression on 3 adjacent cylinders?
Thanks very much for your time,
have the same problem?
