oil pressure drops under load
I have a 92 4.0L cherokee. the oil pressure runs 30-40 at idle but when i accelerate it drops to just about 0. When it get around 2k rpm and up it begin s to have a small clatter in the engine when the oil pressure hits 0. The engine has 167k on it and it solid. With the jeep in park i can rev it with consistent oil pressure between 30-40 with no chatter. So it seems as the issue is only when it is under a load. i checked the oil and it is at a good level. im thinking it may be the oil pump? any ideas? thanks

Mine did this but didn't make any noise. That kinda scares me. I would walk to the parts store and rent a mechanical gauge. Then test it before you drive it much. Mine was just a loose wire. I figured this out after i replaced the sending unit.

Verify oil pressure with a mechanical gauge. Remove the oil pressure sender located at the oil filter adapter, screw in mechanical gauge in there.
Verify your oil pressure with a mechanical gauge. They can be rented from many big box parts stores. GOOD DATA = GOOD DECISIONS |
