Help..Lost Oil Pressure...

[86 CJ]

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 with a 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 ((
??????

Pan off? to get to the sending unit??

What your saying about the gauge at the block is your sending unit. Use another gauge if you have one readily available. Replacing the filter is also a good idea especially if its a Fram. If none of those yield higher oil pressure then drop the pan and check see if the pick up screen is blocked.

A flat 0 on your oil press will net you a roasted engine in nothing flat. Unless you're hearing some pretty gnarly and unhappy noises from under the hood, and some hight water temps, I would highly suspect a bad guage.

I broke a push rod once - the lifter popped right out of the galley and made my oil pressure reading go to zero. What engine and is it running smoothly?

I'ld bet on a plugged up sending unit if it is electrical.
Replace it with and underdash mechanical gauge.

Or you could mount it in the dash if you cut out a hole the right size for the gauge.
