'03 f350, Last year it blew a connecting rod out the side.(110,000mi) Bought a flood recovered 6.0 from a freind of a freind. Completely dismantled it. Had it honed, crank polished, all new bearings, head studs, egr deleted, black onyx head gaskets. When I fired it up, it had very low engine oil pressure and also a leak in the hpop system. Had enough fun so I dropped it at the dealer to fix. 1 month and $4000 later still not fixed. Brought it home and it sat for a year, then last week I tried to tackle it again. Took the motor back out , brought crank to machine shop to double check the measurements. They polished again and ordered new bearings again. Installed crank,new gyro pump and cover. Put in new stack tubes for hpop issue. I solved the high pressure oil issue, but I still have very low engine oil pressure. 2-4psi at idle and 15psi at 1500rpm. Anyone have any ideas as to what I'm missing here?????
sometimes a bad IPR will cause loss base oil pressure
Pull and check IPR if it got junk in it and is stuck open will not allow to build aANY pressure
look at the screen if pushed from being plugged or any hole in it time for a new on <!-- / message --><!-- sig -->
With all the work that went into this truck it wouldnt surprise me if the screen and such was jacked up
OK I will try the IPR tomorow(tue.) will post the results. One more thing I did find is that I pulled the oil filter, checked both check valves. They were good. Then cranked the motor to fill the filter cup just to double check the valves opening and closing which was good. BUT, I noticed that the oil was airated. Would I be correct to assume that's an issue that would affect oil pressure
