I'm not talking about oil getting to the mains. Talking about mating surfaces. If the oil pump shaft is not down in the pump you could not get the bolt threads started right?
Must be something in that pump. Fishy68 mentioned he found stuff in them from the factory.
I can see what you are talking about if the pump jammed with welding slag or something like that or if there was no screen and it sucked up a small nut or something. The cam would still turn the oil pick up destroying itself and the pump. I hear you on that one.
