Is my oil pump or oil pump screen bad?

Asked by Paul Jan 25, 2015 at 08:30 AM about the 2004 Pontiac Grand Prix GT2

Question type: Maintenance & Repair

Upper and lower intake gaskets were recently changed on my 2004 Grand Prix. After
driving car for almost a week the oil pressure light comes on, I pull of road as soon as I
can and car quits. No check engine lights and wasn't running hot. It cranks, slowly but
won't start. After sitting for about an hour it started, but ran rough. I had a tow home. A
few hours later my neighbor comes over and I ask his opinion as to the problem. We go
out and it starts right up. Running smooth as can be no abnormal noises. I'm like what
the heck. Could this be clogged oil pump screen or a bad oil pump?

I would not risk ruining your engine. If oil light came on and car ran rough, I would get it to the shop and have the oil pump and the oil pressure sending unit changed out.

I thought that also Jim. All fluids are up to par. When gaskets were done I had cooling system totally flushed and filled with fresh, clean coolant. That's what has me thinking it's the oil pump or screen for it.

Oil pump or clogged screen will not necessarily make it run rough unless damage is occurring and it is ready to seize. I would think it got hot ans possibly has air trapped in the cooling system as mentioned above.
