Oil Pressure Question!
I have a 1998 jeep cherokee classic. It was purchased about a month ago. Well the oil pressure gauge was showing 40 when engine started and after it got hot it would drop to 10 at idle. So we replaced the sending unit. Nothing happened. Then our mechanic replaced the oil sensor and now it is reading 40-45 while running and once hot at idle it sits at 18-20. Is this normal?
