Mark, You and others bring about some very good points. I do agree that one of the biggest issue with the car engine is that the cylinders were cooled via a fan that was on the back of the generator. This then forced air through an oil cooler, after which, that same air was to cool the cylinders and head. The #3 cylinder was then the hottest running cylinder. On my bus, I did have an external oil cooler and also had an air scoop on the side of the to force more air into the engine compartment and the oil cooler was mounted so the outside air crossed it first. The bus engine blew up in Minneapolis. In retrospect, I believe one of my biggest issues was getting the valves adjusted to the precise clearances. The other was my young age and trying to drive the VW harder than was meant to be driven. Now I am an old person that knows better.
I have also been very educated from you and others about the valves themselves and did not know the information about how the original valves were produced. Thanks much for the education. Earl
