Sorry it took so long to get back to you there was a little emergency ok little is an under statement any how,
I am very lucky it does not sound like there’s any piston valve contact and this car is amazing that it runs at all or I am not getting it so here goes. When my cam tower mark is aligned with the notch in the cam washer as pictured in the link earlier in this thread my crank has to turn 15 degrees in the proper direction of rotation to be at 0 on the crank shaft. Or as my son calls it “it is 15 degrees positive”
I am correct then that I need a new timing chain?
