Your gauge is reading correctly. You should gain roughly 10 pounds of pressure per 1000 rpms. My chiltons says you should have 37psi at 1600 rpms with the 2.5 4 banger. From what you are saying it sounds fine. If you dont have a maintanance manual get one, or two. I have a Haynes and a Chiltons. I find it good to have both of them so I can cross referance what each says to see weather or not the answers jive. Later, Andy 89XJ 4.0 5-speed
New Jeep Owner Looking for Help
G
I have just purchased a 1992 Jeep Wrangler 4 cyl. w/ hard top and a manual transmission. She's in great shape and the transmission drives tight!! The Gears are all sound and over the 5 days I've owned her, I've had a lot of fun. Here's my problem.
My Oil Pressure guage seems to like to move a lot...especially in the higher RPMs of each gear. When I start it up, and at idle (sometimes) the guage will read at or a little below 40. However, when I start moving, and especially when I get into the top end of my gears, the pressure rises to well above 80. When I slow down, it comes down again (usually). This has me concerned because I really don't want to blow up my new Jeep. Has anyone seen this before, and if so, how can I alleviate and fix the problem? Quick answers qould be appreciated, since it does get me back and forth to work.
Thanx in advance for your time and replies.

Hi Whirly,
The Oil pressure senders have been notoriously faulty in SWB Jeeps for years. I would start there - it may not be reading correctly.

Whl.....it's good to hear from someone who HAS oil pressure...usually it is the other way around. You could do like Ford did in late '53 when they finally came out with their fabulous OVERHEAD VALVE V8....the oil pressure danced all over the guage....so they worked out a solution....they invented the IDIOT LIGHT! What the owner didn't know.....well, let's just say they let sleeping dogs lie. Heh heh. Oh, and one more thing...what's WRONG with blowing up an engine? It's a real growth experience. When I was a kid I worked weekends in a big wrecking yard cuttin' up the tired, per-war, Detroit iron. Sometimes a junker would get up to the "choppin' block" intact enough to still run. We would sometimes reverse the throttle spring, and start the engine. We would stand back while the engine revved into never-never land and blew up. Like I said....a real growth experience.
