Re: Oil Pressure & restart after oil pump overhall

I guess I see the question as: What do I do if there is no pressure? I had a problem of priming the oil pump on my '47 Custom Clipper with the 356 engine. I know the V-12 is a much different type of engine, but the following may be helpful to you.

I had had the oil pan and screen off for cleaning and it had been several weeks before I was able to restart the engine. Cranking the engine with the spark plugs removed to get oil pressure in the system before starting it revealed that there was no pressure being registered on the gauge. I removed a main bearing oil gallery plug and no oil was being spurt out when the engine was cranked. I posted the problem on this site and got many suggestions. The one I followed was to introduce some oil into the system by removing the oil pressure sending unit. With necessary plumbing I pumped in a quart of oil. This solved the problem, the pump was able to prime and produce flow and pressure. I checked it by again watching if any oil came out of the gallery plug fitting. Cranking the engine made a nice mess on the floor.

This is what I had to do for my engine. I hope you (and others) find it helpful.
