#818 of 5143 Oil pressure problems
Jun 30, 2004 (7:17 pm)
This is for our 1994 Jeep Grand Cherokee 1994.
I got a few problems. Maybe all related.
The oil pressure gauge keeps going up and down, depending on rpms. High rpms, high pressure and vice versa. It only does it when engine is hot though. I checked the oil. I am loosing (burning) some, maybe half a quart per 500 miles. But it has 104k miles. So that is not that strange. I opened the oil spout. At hot engine temp, there is very light smoke from the heat coming out. Is that normal?
Also, when I get out of the car after parking, there is a slight odor like that of warm, slightly burnt rubber. Could it be related?
Does anybody know what my problems are?
Should I even worry with 104k miles?
Thanks so much in advance.
#820 of 5143 Resale/trade value

I have a 2001 JGC and am looking to get rid of it. I am on the 4th set of brakes (warped rotors) and it is currently in the shop for transmission problems (53K miles). I only have 20K miles left on the extended warranty and want to get rid of it while it still has some value. What kind of trade/resale value can I expect? Is the trade estimator close?

Water pump bearings can go any time. Have you changed anti freeze every 36 months? If not, its your fault the bearing seals were eroded by acid buildup in dirty AF! Most premature failures like this are maintenance related. "pay now, or pay a lot more later!"

You probably have debris in the intake air vents. Remove the cover and clean it out making sure drain holes are clear. Flush with mild clorox solution. My Dodge did the same thing too.

Try Auto Zone or PEP Boys. Their standard rotors are pretty good out of the box. You may want to try the organic brake pads instaed of the metallic. Don't last as long but cheaper and dissipate heat better.
#824 of 5143 Rotors, have you replaced the calipers
Jul 06, 2004 (7:46 am)
There was a TSB (easy to find in this string via search) that indicated the problems was faulty calipers that did not release from the rotors. Heat builds up and they warp, that is why replacing the rotors does not solve the problem.

I absolutely had it maintained properly. I don't have my service file in front of me now, but I know I had the coolant serviced well within the limits, I believe I did it at 24 months with around 24000 miles.
