<VV> Which OIL? Re: Doc opinion

[Bob]

Hi Frank,
I only had about 500 miles on the motor at the time and I was still using dyno oil. I was planning to switch to synthetic after that very trip! 
Regards,
Bob

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.
