High Oil Pressure - '99 TJ with 99k miles
 

Hello All, I have a 99 TJ sport with about 99k miles on it. The engine
oil
pressure two days ago pegged itself at 80psi on the gauge and has
stayed
there. It normally sits between 40-60psi when driving and below that
when
idling. The oil has been changed every 4-5000 miles, there is no
knocking
and the engine sounds fine. I did an oil change this morning and the
oil was
practically pristine so I'm some what confused. Also when I turn my key
in
the ignition before cranking the engine the oil pressure gauge goes to
50
without the engine running. I also went on a drive yesterday (100miles)
and
after about an hour of driving the oil pressure at idle would go down
to
about 60-70. I have heard these little oil gauges are notorious for
crapping
out so I'm wondering where to start. I have checked for oil leaks since
high
pressure blows a gasket and there are none. I don't own a pressure
testing
kit and the only ones I have found are $100-150 so that's out. I don't
have
the money to throw parts at it at the moment and it is my daily driver
so
how can I diagnose this issue? Where would I start? Should I actually
take
it to a shop for a check?

Thank you for any advice/help ahead of time,
-Stephen

Re: High Oil Pressure - '99 TJ with 99k miles
 

Start by replacing the oil pressure sending unit, which is relatively
inxpensive and easy to swap out.

With that known OK, it's time to swap out the guage internals. If
you're getting a reading of 50 when the engine is off, and the sending
unit is known good, it's time to swap this out.

If it's working at all (needle moves), place your bets on the sending unit.

Cool, thank you for the advice. Since the pressure sensor is not the
same place as my old jeep. The manual i have is a tad outta date 1987.
Which manual would anybody suggest? Haynes/Chilton some other?

The Dealership one is $130 so thats out.

Thanks Again,

Oil pressure sending unit. They seem to go out frequently. I've replaced the one on
my 98 3-4 times now. Pegged high is a normal symptom for this, or pegged low too.

Re: High Oil Pressure - '99 TJ with 99k miles
 

If the wire to the sending unit is shorted to ground it will peg on 80 psi.

You can rent a mechanical gauge, often at no cost, from many auto parts
stores.

You should check the actual pressure with a mechanical gauge before you
start replacing parts willy-nilly.

If you don't want it to replace it every few years, buy the OEM item.
I've discovered this the hard way. Most aftermarket parts are junk.

I thought of something else that may help you. If you disconnect the
wire from the sending unit and your guage reads zero before/after
starting, you can be even more sure it's the sending unit. Try this
before replacing anything.

I sort of agree, but I haven't had your experience. Car manufacturers don't
*make* cars - they pretty much just assemble them.
(While this is possibly not true for engines, it is true for practically
everything else, especially sensors). You *can* buy a quality aftermarket
item made by someone whose name you recognise.

Re: High Oil Pressure - '99 TJ with 99k miles
 

You're talking about the manual, right, not the pressure sensor?

That's about the going rate for the manual. But IMHO well worth it. No
guesswork like you would a Haynes or Chiltons.

Re: High Oil Pressure - '99 TJ with 99k miles
 

FWIW, there is a gauge check routine. My '97 FSM says put the key in OFF
position. Press and hold odometer reset button. Turn key to ON (not START).
Release odometer reset button. Guages should all move through their ranges.

Release odometer reset button. Guages should all move through their ranges.
