Yes, hitting a valve I bet. According to lower & upper timing marks the engine is 4 degrees retarded. It is a 616 with a ton of miles so I was going to replace timing chain anyways. Will undo rockers tonight & try again. Do I need that guide pin out on the bottom, I have the tensioner & upper guide pin out.
