I have a 96 cherokee 4.0 h.o. that has a grinding noise on the bottom of the engine coming from around the oil pump area (internal) I don't think its the rods, bearings, or lobes because it would knock, no knocking , just a grinding noise. intermittent with the engine. sometimes it's not very noticeable. could this be my oil pump or distributer shaft? no loss of power. the oil guage did go way past 80 and hasn't moved since, not even when I shut the jeep off. otherwise it still runs good..
