Re: oil pump priming postwar 327/288

The oil pump is a positive displacement pump, and designed to be self-priming. With the pump and engine internals in good condition, even at cranking speed on the starter motor it should be able to deliver a small but measureable positive oil pressure.

Good point by JWL, an open relief valve would explain your condition.
