I admit, I am a Jeep 'tard!
I have a 1994 Cherokee Sport, which I have been enjoying immensely.
It leaked fluids like nothing going when i bought it, so I replaced the valve cover gasket, which was probably unnecessary, as I discovered the rear bolts were barely tightened. Then I replaced the transmission pan gasket, as it was leaking and discovered that the PO (I assume) had allowed the gasket to slip when they replaced it and an entire corner was not sealed at all.
So I have gone two weeks with no bodily fluids draining on my now clean driveway.
TODAY, my son started it and I peeked under to see oil pouring onto the driveway.
Popped the hood and discovered this part had apparently come apart at the end.
It is a piece of rubber (I think) and I can push it back with my fingers, but as soon as the engine is engaged, it pops off again. It feels like there are wires that attach somewhere, but I ran out of daylight so I cannot tell where they lead. Where do the wires go?
The second pic is pretty crappy, but hopefully y'all will get the idea.
That is your oil pressure sensor switch. Replacing the rubber back into the top will likely do little. It needs to be replaced if it is leaking. Cheap parts store replacements tend not to last, if you do get a parts store one, get one with a lifetime warrantee. You will need it. Best route is to replace it with an oem jeep dealership sensor. A bit pricey though. I replaced mine with a 15 dollar mechanical gauge from a parts store. So now I have an aftermarket oil pressure gauge. Got tired of those things popping on me.
That is the switch gone bad. Mine did this a couple months ago. The actual switch starts to leak oil and it goes into the plug part and builds pressure and then pushes the rubber piece out. Replace it asap. I waited a day to late and at 4 am headed to work mine pretty much gave out and I lost about half of my oil before I noticed the smoke billowing in my rearview. I replaced mine with a autozone part and it has worked fine. Although the dealership part would be better if you don't mind spending the money.
Careful taking it off, it looks like you have the elbow into the block. Just apply even pressure when unscrewing it, and don't overtighten or under tighten the new one when putting the replacement back on. I would be very concerned about driving it at all until you get it fixed as well. Engines don't do well with no oil.
Got the sensor installed, and taped the heck out of the harness, but somethig still is not right. I am not happy with the gauge readings.
It is reading about 60 at idle and 80 when accelerating, higher than it was.
Well if the one before was leaking then it was not getting a correct reading. I'm sure due to the lack of good pressure it was reading below what it should. I don't believe those numbers are outrageous. After I drive mine a while the pressure decreases a bit. Did you drive around any or just crank it and get those numbers?
