Diagnosing incomplete oil pressure on a small-block Chevy


#1

Nothing is more important to your engine than the flow of oil. If oil stops coursing through the engine’s passageways, the result will be catastrophic failure. This is why nearly every car has an oil-pressure warning light. If it comes on while you’re driving, stop immediately. You may have only seconds before major damage occurs.

I had the oil pump pickup come off of the oil pump in the 283 in my 59 Corvette. At idle and highway speeds pressure was normal. At high RPM the oil pressure would drop to near zero.Lucky no engine damage occurred.
After that I would braise the pickup to the pump.
