I found a very interesting story on oil for an early Corvair. The writer is Richard Widman. I asked him what is best to use in a Model A.

Re: oil grooves

Brent, I would appreciate that very much ! Meanwhile I bought the calculating software I was talking about. When I can spare the time I will try to use it.

Finally checked the camshaft timing. That was completely wrong, 10% off !

Re: Oil grooves

Rick,

The rebuilder also out felt in the groove holding the oilslinger. How do I get that out of the upper part of the bearing end with the crakshaft still in place ? Any ideas ?

Re: Oil grooves

What grooves do is promote leakage ! Grooves in the lower part, the bearing cap, will create leakage in pushing the oil up the way it came from. Up to the wells and from there, up to the oil entry...
