Bob et al.
Reminds me of the time many years ago when I came out of the store I was shopping at, hopped into "Joe Cool" (1966 Corvair with A/C) and started the engine. It ran fine but the red light on the dash told me I wasn't getting any battery charging so I shut down and prepared to replace the fan belt with the spare I carried. Surprisingly I found that the fan belt was perfectly attached to all the pulleys so I restarted the engine. Now the fanbelt was STATIONARY as was the fan itself and the alternator pulley! Closely examining the driving pulley I was amazed to see the INNER section was turning just fine, but the OUTER section was completely stopped. The rubber anti-vibration layer between the inner and outer had completely failed!! How to get the car home so I could repair it??? Fortunately, the trip was only 7 miles and I had installed a head temp. gauge so I simply drove about 1-1/2 miles until the gauge went up to 400 deg.F. then stopped and let the engine cool down and repeated the short trip interval about 4 times. What saved me was a BIG battery AND the synthetic engine oil I had in the car. After arriving home, I dropped the back end of the engine a few inches and changed the vibration damper pulley out for a good one and the car ran just fine for many more years.
"Joe Cool" (named by my little boy after the Snoopy character) had his cooling system adjusted so he blew 38 deg.F. air temp out of the cooling duct (as measured by a digital thermometer). It was so cold when I put my fingers by the duct outlet for a few seconds they would HURT from the low temp. Try doing that with a "modern" car!!
Thanks for the memories!

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!

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

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
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
So cooling is VERY important when you stress Corvair
engines beyond their normal "in-car" mode.
PS I am
it as we speak and adding a fan driven external oil cooler!
