Hi all,
Im trying to sort out some rough running issues with my parents VZ Adventra with the LY7 3.6L V6. I suspected coils or plugs so i changed them and made no difference and ran even worse. I put the old coils back and it still ran like crap. Took it to the mechanic and he said its probably skipped the timing chain but its not a cheap job so im having a go at it. I confirmed that its 2 teeth out but i also found that the rocker on one of the exhaust valves on cylinder one has come off.
Im about to order a new chain kit but before spending the money id like to ensure theres no valve damage and why that one rocker could have popped of. Does anyone know if this is an interference engine? and if 2 teeth out would allow the valves to contact the pistons?
Does anyone have the torque specs and sequence for the cams?
Any info or advice would be greatly appreciated.
Cheers
