25/2 hot engine oil pressure

[tlfrantz1]

Guys,

My 25/2's oil pressure goes to near zero when the engine gets good and hot---200-210 F---it starts out about 20 psi and steadily drops as the engine heats; its done this every time I've run the engine. I have 30W non-detergent break-in oil and an oil line feeding the outboard injector cam lobe. I have been overloading the engine and getting it to 200-210 degrees to seat in the rings and so far it seems to have worked well as I have no slobbering issues whatsoever.
Anybody else have this same oil pressure problem?

Thanks!
Tommy
