EB- If the sump has 90% air in it when the engine is running then what is the oil pressure gauge reading? Scary to think your pickup/oil pump is sucking foam.


>>>*Used to scare me, too, especially since I knew it was doing that even early on when we were drag racing. Then one day I was down at Kay Sissel's shop in El Monte, got invited over to Moon Equipment's dyno shop to see some neat stuff. (I was a mid-20's kid and it was like a candy store in there..)

They had an engine with a clear oil pan they were testing, I stood there and watched the oil "float" alongside the crankshaft which looked like it was just sitting there wrapped in oil. Every once in awhile, the oil would go WHOP! and fly all over, the whole process would start over.

It would then get hard to see, soon it would clear up and all that would start all over again. Once the oil got really hot we couldn't see in there anymore, it looked like it was spraying all over the place.
Interesting stuff, I learned a lot that day back in February 1969.....*EB
