Re: Question for Timing,,detonation in engine
Ah, this sounds like a belt change without locks gone bad, if your engines runing, place your hand on the intake manifold, it should be cold when runing, if it's hot to the touch you have bent valves in the corresponding cylinders, this is a sure sign that the belt is not tensioned correctly, as for the pain marks, after 16 (I think) revoloutins of the crank the mark should line up again on the cam, this is because of the length of the belt and the difference in size of the cams to crank pulleys (1:2). But if you rotate the crank twice then the cam should be back on position.
