<VV> Which OIL? Re: Doc opinion

[frankcb at aol.com]

Bob, were you using a SYNTHETIC engine oil at the time the damage occurred?  Usually they're good up to 450 deg.F. which is quite a bit higher than conventional oils.

Hi,
And on a somewhat related note, I seriously damaged a freshly built 3.1
in
my UltraVan about 18 months ago. I did all the required deflashing, etc.
but
made a huge mistake in not installing additional cooling power in the
form
of an external oil cooler. No problem for short trips around home but on
the
first long trip, up a multi-mile very steep hill in the Rockies with a
full
load of vacation supplies I cooked the oil and damaged all 6 pistons
and
cylinders beyond repair. An expensive lesson and with 20:20
hindsight
totally preventable.
So cooling is VERY important when you stress
Corvair engines beyond their
normal "in-car" mode.
Regards,
Bob
PS I am
rebuilding it as we speak and adding a fan driven external
oil
cooler!

Appreciate Doc's detailed
dissertation on FC engines and driving.
Agree they need to be handled
differently than cars.
Have experienced engine failures on Ramp and Brier
bought from long-time
owners that were tuned by "professional" Vair mechanics
but lacked suggested
modifications.
Many of us are not gear heads and depend
on others for service and repairs.
We need to know the realities of our lovely
old trucks.
