Is there a problem at the oil pump drive end? Imagine an oil pump that is very hard to turn (mega high pressure) or very tight idler gear, that would impart a forward thrust on the cam from that gear at the back end.

Can't really se that being it, but I'm racking my brains to think what could cause the cam to thrust forwards.

The cover was brazed, do you think it was finished to the correct height?

Would a replacement cover that is not damaged possibly be all that is required?

I'm interested to see what unfolds.
