Working on a 90 Sport w/ 4.0.
Slowly my oil light has been coming on (no oil pressure guage). It's got to the point that it remains on when the engine is cold. This is odd as in my experience usually when the engine warms up the oil light will come on when a pump is failing. So I changed the oil pressure sensor and this had no effect. Does this sound like the oil pump or something else I might not know about on these 4.0's.
It's just very odd to me how the light stays on when the engine is cold but when it warms up it stays off (for the most part, might flicker every once in awhile).
Are the rebuild kits any good for these or would that be a waste of time.
BTW.. Yes I checked my oil level.. I do have a leak which I'm fixing this weekend (valve cover gasket) but the oil is at the correct level.
