I had a V6 with low oil pressure too. I replaced the pump with the engine still in the car (I wouldnt do that again!) and it didnt help a bit. Thinking it was cam bearings, I sold the car.

I am sure they are worn too fred.Today i plastigaged the crank bearings.Not good.The two mains I checked were .002 and .003. the max being .0015.The rods were worse, even with the new bearings.it hardly even crushed the gage.So I think ill put it back together , put 20 50 oil in it and then pull it out for a complete rebuild this winter. It MUST be ready for the Stampede next year!
