possible heads problem?
Ok I'm going to be as specific as possible here. Just bought the car, guy told me he had the engine rebuilt. Well I was putting some oil in it, then started it up and it started making a really loud knocking sound from the passenger side valve cover. Now this is a really loud knock, sounded like someone was punching from the inside of the valve cover. I pulled off the valve cover and it did seem like a few of the rocker arms were loose. They were tight on the fulcrum nut, but still moved around quite a bit. I'm taking the heads off this weekend, but just wanted to know the heads are the problem like I'm thinking or if its something else. By the way its an 82, so if you guys could help me out I will really appreciate it
