<VV> White pushrod tubes

[N. Joseph Potts]

Re #5: my "natural" pushrods don't leak. Haven't for years. Then again, I
rarely take them above 1,000ft altitude, for whatever effect that has.
     Gear down!

I'll just pose these simple questions:

1. What material are the heads and case made of?
2. What material are the pushrod tubes made of?
3. What effect does heat have on the expansion/contraction of dissimilar
metals?
4. What effect does a white coating have on the absorption of heat on a
metal next to a heat source?
5. Are the pushrod tubes normally a major source of oil leaks in a Corvair?
6. Would it be smart to find out what others have done to reduce oil leaks?
