Thanks. That sounds like some good advice. Ill find some time in the next few weeks to test it the way you described. Like you said. Its better than throwing parts and money at it will no good direction. I did key in on what you said about the timing marks. I cant tell you how many times i went back and checked the marks and all look good, but when you mentioned the slack... if i put the belt on from the intake cam gear first, then the exhaust cam gear, would that put the slack on the wrong side and cause the issue? The marks all line up when the engine is off, but would it slack up too much and cause a valve timing issue? It dont sound logical but its a thought.
