Re: Oil pressure at 10 psi

If the problem is happening at driving speed and the spring and pressure relief valve is OK another question is did someone "rebuild" the oil pump when doing the other work. Several have had issues with oil pressure after the pump has been worked on because too thick a gasket was used on the end plate when putting it back together.

As to things that might have been left off, there is a plug with an orifice at the front of the lifter gallery that if it was missing would let oil drain into the timing chain area. The lifter gallery pressure would surely be affected but not sure whether the overall pressure would be lowered to the extent you are seeing.
