If I might ask a question about re-building these engines. I was told that the cranks are reused and polished and run standard bearings . I have an engine that has low oil pressure at idle when motor is at operational temp.If I run the motor hard and come to a stop it will trigger a low oil pressure warning light while stopped till I drive again.Once idle come up light goes out.I did the oil pressure bypass update. And this did nothing for the problem. So the problem must be to much clearance between the bearings and crank journals.So the polishing of the stock crank will remove at least .0005 a half thou to a thou .001 so any rebuilt motor will have a low oil pressure a lot sooner than a motor with a new crank. Can the crank be welded and ground to stock dims.
