Low Oil Pressure after replacing oil pump
#13
10w-30 is the wrong oil to use, 15w-40 is the correct oil to use.

Thanks for all of the input. It has been a week since the new oil pump was put in. The oil pressure when warm is 60psi at 2000rpms and between 4-10psi at idle. It has not dropped below 6psi in the last few days (no warning light). The truck is idling at around 500rpms. I am going to clean out the throttle body and idle sensor next to see if it is due to low idle. Could the new pump have taken a few days to prime correctly? is idle to blame? or is it most likely bearings on a 15k rebuild?

seem like you keep going back over the same stuff, dump the 10-30, it is not helping your problem.
Fill it with 15-40 rottella, get an oil preasure gauge and an OBDII scanner, have someone hold the idle at 700-750 and record your readings hot and cold at idle and at 2000 rpm and get some real information.
Most likely a combination of the wrong weight oil and to low and idle. while you have the scanner find out why it will not idle.
And Yes, I have seen rod and main bearings wipped out in a lot less the 20k miles, if it was not macined or assembled correctly, there are a lot of people that with throw rods and mains in right out of the box without plasticgauging them.
