Avoiding burnt valves?
« on: March 20, 2019, 12:01:21 PM »
I’ve just done some head work on my 1990 air cooled after losing compression on my second motor. I discovered both motors plus my parts motor had heavy pitting on the exhaust valves which caused leaks.

Is this a well known issue on these cars? Is there any preventative?

Could it perhaps need some lead replacement additive?

Possibly, I thought that affected the seats but I guess both?
