A friend of mine in Daytona has a 97 Sahara with the 4.0 engine. Around 92k miles. She just bought it about a month ago.
She called a little bit ago and the "check guages" light came on in the cluster. Her oil pressure guage reads just barely above zero when it is running. She has checked the oil and it is full, there are no leaks anywhere. What stumps me is this: I would think that if an engine is running with very little to no oil getting on the top side, you should hear the rockers tapping. She claims it is a silent as it always is.
My first thought is oil pump failure, but the guage/sending unit could be failing as well?
Since I am 1100 miles away, obviously I am not going to be the one to fix the problem, but was wanting to see if anyone else has had this issue so she could be armed with a little bit of information so when she goes to a repair shop, she can be prepared.
