    Well after a weekend of happy plowing and putting the first 110 miles on the Jeep in 3 years after its partial restore project, I went to spray all the salt off of the engine, frame and everything and noticed that I had 0 OIL Pressure on my mechanical guage :( recently when I got it back on the road a couple weeks ago it has always been sitting around 40, then I noticed when plowing its been at 20 most of the time, which is fine. Yesterday I went out and hit some driveways and it was 10. today I am at 0 witha full pan of oil :(( I will check the guage at the block first, then maybe oil filter. I have had one clog before.

    Anyone other suggestions from you Jeep guys before I have to take the whole pan off to get to the sending unit :(((

    Be sure it is not a gauge problem before tearing down the pan.

    Also, you might get a lot of information on the Jeep forum page. You will have to be specific as to what Jeep it is and what year/ what engine you have.

    Thanks Man

    I have been back out there for the past hour. I checked teh clear tube on the guage and blew it out, cranked it up and got about 5-10 psi :confused: Then drained the oil and replaced the filter and BINGO..

    I am back to 50-60 PSI wesport:drinkup:

    This is the second time I have had a new or newer(110 miles) filter suck something up or clog and totally kill pressure to the engine..I consider it an easy fix, and no PAN dropping today :)

    I am Happy now and waiting for more snow to come, just gottta throw my radio in now..

    What engine do you have in your 86, if you don't mind me askin? I have an '80 with a 258 and it never had good oil pressure. It had an electric sending unit that I replace, no improvement, pulled down the pan and put in a high performance oil pump, no improvement, pulled off a main bearing cap and checked the tolerance, it was right in the middle of the range. Long story short, I put it back together and figure, if it sounds good (no knocking) it is good.
