Reply To: Bearing clearances

[David Schaefer]

Very interesting discussion. I had my 1930 straight 8 rebuilt at a shop that specializes in rebuilds and was surprised that the oil pressure runs high 50 psi all the time. The car and motor were in a bunch of pieces “basket case”” when I started to put it together. The wear on the motor was minimal but I thought it would be a good idea to have it assembled by folks that work on motors routinely. The engine has about 4 hours run time total over two summers and the engine sounds very very good. I have changed the oil and have not found any thing that looks concerning. I have used Valvoline racing oil 10W30. I have backed the spring out as far as I think I can go and have tried a different oil pressure gage. Does any one have any thoughts or comments on if this is a problem or anything else I might try? Is this because the clearances are still tight?”
