Oil pressure drops after running 10 min
Before I blew heads 2003 1500 ram 5.9 magnum oil pressure was dropping
when stopping at light / redid heads new oil pump cleaned catch tube in oil
pan but oil pressure still dropping?
As oil warms up the pressure will drop some. If the engine was very dirty with sludge it may be possible that the p/u screen is getting plugged again. Have you put a mechanical pressure gauge on the engine to get an accurate assessment of what the oil pressure really is? Do the lifters start to rattle when the oil pressure drops? How many miles on this engine?
