Engine Mechanical problem
1997 Jeep Wrangler 4 cyl Four Wheel Drive Manual 125k miles

while driving, oil pressure reads as normal between 40 to 60, at idle drops to near 20. Oil pump is original. Do i need to look at replacing the oil pump?

See my profile...Imma CJ Guy As your engine wears----it does exactly as you described. I would not worry until you hit about 15 PSI OR Stuff begins to rattle! The local Production, Auto-Machine Shop Owner (a friend)...[We're not sleeping together, nothing like that!]........Told me that MOST engines are OK down to 4 PSI, before damage occurs! However, I would NEVER let mine go that long! Things that might help....Things I do....Every oil change gets a quart of OIL STABILIZER----$$$...NO OBJECT....only the best for "Mr. Jeep" and "WILLY" '77 CJ 5 "Mr. Jeep"

When you do replace your OIL PUMP----see if a HIGH VOLUME OIL PUMP IS AVAILABLE for your engine. "Mr. Jeep" has a 258 6 cyl. (4.2L)......He has H.V. Pump (2nd engine w/ many miles).....O.P. 30 at idle.....40-60 on the move, "WILLY" L-134 (flathead) 4 cyl....O.P. 40 at idle 50-80 on the move.....stock oil pump! Whaddu Think? Respond The Medic
