Re: Motor questions Could the rings be bad?
When you do the compression tests, make sure you run two seperate tests. The first one is called dry. The second is called wet, it is called wet because you squirt oil into the plug hole. If the rings are worned the additional oil will help seal the piston. If no change then the top end is the culprit.
There are others here that can give you a more specific break down of indications.
