<VV> Oil pressure regulator spring, my take

[Mark Durham]

Randy, that technology does not relate to later engine designs, the
difference being if you want to change your bearings every 20 to 30 k
miles splash worked. These engines are designed to be pressure fed to
provide the needed boundary layer of oil in the bearings, plus
everything else is pressure fed in the corvair engine. However, if the
light switch is accurate and it stays off when the engine is warmed up,
you are correct, there is enough pressure at idle for the stresses
involved. I would be more concerned about low pressure above idle, if
pressure above idle is correct, then idle pressure is ok if the light
stays off. i used to work on 6 cylinder aircraft engines whose oil
pressure at idle could be as low as 10 psi. They were 375hp, never had
a oil related bearing failure on them. Pressure above idle was 45 psi.

It would seem all this hub bub is much ado about nothing.  If the
light doesn't come on, and the car runs fine otherwise, don't worry
about it.  Why?

Weren't all the old timey cars lubed with "splash" lubrication?  My
first car, a '41 Chevy was.  And while in the Navy,  I drove it all
over the U.S. with zero problems.  I think it ran at 15 psi most of
the time on the gauge. (The gauge read 0 to 30 psi)
