ok so I took my jeep wheelin about 2 weeks ago and got into some serrious mud. I think too much mud (if thats possible). My 98 chero is my everyday driver and today I took it on about a 2 hour drive (highway) and everything seemed fine except the oil pressure gauge. at 70mph and about 2500 rpms my oil pressure gauge would randomly drop to about 10-20 then cruise right back up and sit at about 40. I went through so many oil pressure sensors in my 95 YJ but im not sure if I got mud in the sensor or what? and yes i bathed the jeep a few times since wheelin. any ideas?

 

h20/mud in the connector for the sensor most likely

 

My 96 had oil pressure issues....would float to 20 pounds on startup and drop to zero.....changed pressure switch (10 minutes) and nnow have a constant 60 pounds of pressure....cheap fix

 

I knock that little wire off half the time when working on that side of the engine so I know that it can be a loose connection. Check that it is tight and see what your readings are then.

 

idk how guys do that...

I've NEVER had it get in the way. whenever on that side of the engine, I just avoid it, or work around it.
