<VV> Painting pushrod tubes (from Finch book)

[Andy Clark]

As I recall, the suggestion to paint the tubes with VHT (white) as you
described, was for heat rejection; i.e., to reduce heating of the returning
oil in the pushrod tubes.
I don't remember that it had anything to do with reducing leaks. As Lon
correctly states, the solution for o-ring leaks is viton.

reminded me of something. Years ago when I did my first O-ring job, I  used
the recommendation in "How to keep you Corvair alive." I painted  the
section of pushrod tube that runs near the manifold with VHT paint.  It's
now 10 years later. My dad has the car, and there are no leaks.

about 7 years with no leaks. Has anyone ever determined whether the  method
I described has any real effect on leaks, or is it just a myth?  Maybe the
Mythbusters should do a show just dedicated to the Corvair.  lol
