I am having what I can see is a common issue among many cherokees.
I have 98 cherokee, 133k. semi-Low oil pressure while driving (30-35), and sensor trips at warm/hot idle when stopping (drops below 13?), Pressure is 50 at start up.
Changed sensor to OEM, changed the oil pump today to a new OEM mopar (ya lots of work...).
Still same issues, motor seems to run ok, plenty of power. Have noticed it runs at about 215F-220F, a little past the center in town driving and right on the half mark on the freeway.
Old oil pump looked well used, maybe the oil had not been changed as regular as it should have been.
What else can I do?? I do not want to get into the bearings and such in the motor as I dont have the garage time to do that, I basically rent my brothers garage to do all the work.
I am concerned about it, I dont know if I should continue driving it, it runs fine, doesnt overheat and doesnt have any hard work its doing, no towing right now or naythign like that. motor doesnt seem noisy, not for a 4.0.
I am running SAE 30, I put in a Wix filter for that model motor, etc.
Any tips, tricks to get the pressure up, I was thinking 20-50?
What filter DO increase pressure from your firsthand knowledge?
