Ecotec 2.2 jumped timing. Timing chain loosens and tightens as I turn crank. Need some suggestion on why it's doing so. I'm certain the piston hit intake valves on 1 cylinder which I'm pretty sure caused the valve lifters to break. I hope I only have to replace timing kit and worse case them 2 valves. Just want to know if the timing jumping could bend crank or cam shaft. If not then what else could be causing the tighten/loosen of the timing chain. It is a dohc by the way.
have the same problem?
