Started the pathfinder up this morning and the usual lifter rattle did not go away, and my oil pressure light would not turn off. Checked the oil and it was a bit low, so I topped it off and started it up again. The noise seemed quiter but the oil light still wouldn't turn off. I was running late for work so I figured I'd give it a mile or so to warm up and see it the light would turn off. Didn't make it that far before the engine started dying when I would come to a stop oir even when I would just put the clutch in without reving the engine.

Made it back home and decided to try some seafoam and a new filter in hopes that would free up a clog and get oil flowing again. That doesn't seem to have done much, and when I drained the oil there wasn't any sludge or chunkyness at all. The oil was dark but looked pretty normal to me. I took the right side valve cover off and everything looks nice and clean up there as well. Put everything back toigether with fresh oil and I still don't have any pressure.

At this point I'm thinking I need to check out the oil pick up filter for clogs and look at the oil pump. Is there anything else I should check before I do all that work or anything else you guys can think of that would be causing me to have no oil pressure?

I should note that this engine has ~268,000 miles on it. I have only had it since 262,000 and have no service records.

Could be a clogged pickup, bad pump, or bad pickup tube o-ring (not unheard of for those to shrink or crack over time). Could be a restrictor in the head has popped out. Or just a flat worn out motor.

 

Warming the oil would reduce the oil pressure. Cold oil is thicker.

I'm hoping for a clogged pickup. I took the new filter off to see if oil was getting that far and it was totally dry. I worked on getting to the oil pan most of the afternoon, and have made quite a bit of progress. The front differential is just about ready to come out but the bolt holding it to the right side of the crossmember is stuck. I'll get back at it tomorrow after the PB has done it's job.
