XJ oil pressure reading?
Just bought an 86 Cherokee 2.8 and oil pressure readings seem weird.
I've just read all the postings covering low oil pressure. (A lot of
postings.) The sender often seems be the prime suspect.
When I first start the engine the gauge shows about 40 pounds and
drops to about zero before there's even much heat in the engine. It
stays there if I run the rpm up to 3500 or so. No warning light comes
on. There are no rod or lifter rattles or knocks that I can hear.
Nothing that sounds like main bearing "clunks" either.
Odometer says about 165k. Seller says it has only been started every
couple of months for about 1+ years. Hasn't been driven because of the
oft mentioned black smoke,stumbling throttle response, rough idle
thingie, whatever that is. She claims no history of low oil pressure
problems. Oil was down a quart and dirty when first checked.
I'm afraid to drive this thing home.
Suggestions?
Thanks,
Lance Ferguson

Re: XJ oil pressure reading?
Have a tow service bring it to your home. Then work on it at your leisure.
Does this beast have a carburetor? Black smoke could just be a stuck or
non-working choke. Get a new sending unit. They are cheap.

Re: XJ oil pressure reading?
Be sure to throw a mechanical gauge on it before
replacing the sending unit. A lot of auto parts stores will 'lend' you the
gauge..

Re: XJ oil pressure reading?
Well, mystery solved. I couldn't find a mechanical gage to test the
oil pressure. It occured to me to buy an aftermarket kit to mount an
auxillary gage and premanently replace the old sender and gage. This
avoided replacing a part with a bad failure reputation with another of
the same.
It cost 16 bucks.
The oil pressure is really just fine.

Re: XJ oil pressure reading?
Well, mystery solved. I couldn't find a mechanical gage to test the
oil pressure. It occured to me to buy an aftermarket kit to mount an
auxillary gage and premanently replace the old sender and gage. This
avoided replacing a part with a bad failure reputation with another of
the same.
It cost 16 bucks.
The oil pressure is really just fine.
