I have a Mzzda 626 with the 2.0 twin cam. I got the car after it had jumped timing. Im not sure which two marks on the cams to use to set the timing and also not sure if it is a zero tolerance motor. Does the valves normally have to be replaced. Im kinda stuck. If i have to change the head on the car or not. Does anyone know anything? Thanks
