I think when I stuck the cover on the intermediate gear, it spun the cam. Thats the only thing that makes since. So I got all the front torn down. If I take the intake off and pull the valley tray, I can check all my lifters, plus pull the cam straight out and turn and go back in. My cam gear has 52 teeth. Got to be an equasion to figure out if its one or two teeth.All the valves open and close as they should. I also thought if a valve was bent I think there would be 0 compression on that cylinder. But I have had bad experiences when I think! Birdtracker
