Re: 327 Compression Test - Results
Sometimes a rocker arm stud can pull upward out of the head. Usually if this happens you can see a clean ring around the base of it where it used to be in the head. Sometimes a pushrod can wear out at the top and it will get all eaten up at the tip by the rocker arm. Those are a couple of the more simple reasons that a rocker will loosen without the actual nut backing off.
