no there are two different switchs one for a light and one for the gauge.You have a factory light and factory gauge ar factory light and after market gauge?? you oil pressure gauge does this also?http://www.autozone.com/autozone/par...mString=search

 

is your gauge mechanical or electric

 

I guess mechanical. Its a needle on the dash.

 

thats electrial a mechanical has small tubing going to the back of the gauge that oil actually runs to the gauge thru ,the one you buy and install your self

 

this is what mine is. I have a 1997.

factory gauges are electrial with light or gauge its still electrial

 

Ok. makes sence.

 

Sounds like maybe a plugged oil galley? It would have pressure until it got all the oil pumped up to the top end and then start starving for oil. But you say it drops gradually, which doesn't make sense, since it would just drop to zero when it sucked the pan dry.

I'd go with the plugged pickup screen explanation. It's something you can check out without having to really tear the motor down.

 

This is all stuff I mentioned earlier. Hardly negative help.

 

thats whats puzzeling the way it drops and how long it takes to drop,as i did the rear main about 3 years ago and pan was clean did valve cover gasket since then and rocker area was the same.seem like pick up tube problms to me could of poss cracked above screen so it will suck oil untill it gets below crack then the pressure drops when i pull over it drains back down to above the prob are then pressure goes back up

 

ok first thing i did this morning was replace the stp oil filter i had just installed2 weeks ago with last oil change got rid of the fram fearing the things i had heard on here about the trouble with them ,put back on a fram problem solved 50 psi at 60 mph 25 psi at idle it was that simple have never had a oil filter have this effect b4 but all is well i thank every body for the replys and ideas of the possible probs back to the mud this weekend to tear it up

 

Cheap fix. Excellent! Good thing you caught it before the engine burned up!

Next time get a WIX or a MOPAR filter.

I wouldn't put a Fram filter on a lawnmower.

Engines are too expensive to run cheap parts.

 

you use waht you want on your lawn mower, ill use what i want on my xj

 

Using what you wanted to use on your XJ just about burned it up.

I know that you dispense a lot of advice to people on this Forum.

And that you believe that your automotive experience and knowledge is nearly foolproof.

What if you had told someone two weeks ago that STP filters was the way to go. That's what you use on yours to "save money". That you had "never heard of" a different filter causing a lack of oil pressure. And they burned up their engine based on your advice.

You want to burn up your own Jeep, fine. But the line needs to be drawn on giving someone else bad advice that could cost them thier Jeep.

 

if you read my problem solved post you would see i removed a fram and put on a stp going by the things i had heard on hear about them, i went back to the fram because i was trying to fix oil pressure problem that was puzzeling me, and no my replys are not foolproff nor do i recommend members do any thing i suggest i just give my opinion i do not ever questiuon the knowledge of the member i am trying to help or make sarcastic remarks of their knowledge what if a member had the same problem as me and followed your suggestions to me that my bearings were bad and changed them that would of been alot of that members money and time waisted from your lack of knowledge regarding my oil pressure problem showed by your answers partner
