OK im on my lunch break so have to make this fast. I was changing the oil filter on my 93' cherokee xj country. while changing it an old plug broke. its not a spark plug, but is right next to the oil filter. I think maybe the pressure sending unit, but can't be sure. Please somone help. pics, explanation on how to fix, and where to get part would be great!!!!

Gee oh Dee

Sounds like its just the sending unit. Not super critical, its just for the gauge. May have a CEL or check gauges light.

A pic would help.

This is also OEM Tech, not Advanced Tech. Moving...

does it look like this?
were did it break?
and 50 bucks at napa
if it broke that the very tip you might be able to get a pair of vice grips on the nipple and take out, it should only be hand tight, well like old rusty hand tight

Gee oh Dee

And if its just the sending unit why the rush to fix it?

jaredhank

that is what it looks like. and I didn't know which thread to put it in. also. If it is the sending unit, I shouldn't drive with it off should I. Thats the rush. got to make a long drive tomorrow

were did it break off?
and depending were it broke off oil will come shooting out of it once u start the motor thats how they work , oil presses against a plunger and spring if it broke off after the spring retainer i would imagine it would just push the plunger out, unless they have it designed were the plunger can only go so far, anyways im not an engineer but i've seen some broke of cat engines and become a laser beam of hot oil haha

Gee oh Dee

When I read "an old plug broke off" I figured it was just the wire. Not the entire thing.

Sounds like you just broke the sending unit.. I did the same thing on mine during my first oil change .. I'm super careful now

thanks everybody. I got a new sending unit. and am almost on track. Ill post pics of the jeep soon. its still all stock, but got the 4.5'' lift in today!!! gonna start building it up next week!!!

Gee oh Dee

I now realize why I thought this.

Title just says the wire was broken. And if its just the wire no oil will leak.

jaredhank

yeah I didn't know what it was at first. but thanks to ya'll I got a new one on. now need to figure out some hoses that broke off and Im set to drive. but those aren't any problem

You can get one from autozone for around $25. From someone who has replaced 3 of theses in one year, just go to the dealership and get it for around $50 it is a much better quality sending unit.

jaredhank

autozone didn't have them. but I got one from pepboys thankfully.

vacuum hoses will get you into hotter water than an oil pressure sensor!
