Question about 1991 Jaguar XJ6

1991 Jaguar XJ6 180K Low oil Pressure and Leaking Power steering

I have very low oil pressure at idle and it stlightly increases with RPM gain but not much. I cannot tell if it is a bearing issue due to mileage, maybe weight of the oil, or bad oil pump. Another issue is that there is leakage from the power steering pump area not sure if it is a seal or anything. I don't know if that is a jaguar specific issue or not. If anybody can please help out that would be great!!

Oil pressure fluctuation is normal in the older XJ's and is nothing to be overly concerned about unless it is frequently dropping below 2 on the oil pressure gauge. As far as the leak in the power steering, it is most likely a bad seal in on of the steering gearboxes. You can get a seal repari kit from numerous different vendors online, however, it is much easier to just replace the entire rack and pinion instead of trying to rebuild the old one. Also, replacing the rack entirely eliminates the possibility of the seals being replaced wrong and also eliminates the possibility of you replacing the seals only to have something else break in the relatively near future.

Did the problem start since the last time your oil was changed? i have a a 91 xj6 with the 4.0 and it had what looked to be a good filter. i changed the filter and now the oil pressure is normal.even if the filter is not that old try to change it and see what happens.

How can I cheat the Idle up? I'm getting a low oil pressure light at Idle, 800 RPM. I would like to increase the Idle to 1000 to keep from getting the light.


that wont work trying to adjust idle can be done on older cars with a carburetor or the older throttle bodies new vehicles trying to do it will set off check engine lights on most sensors sound more like oil worn out---oil filter or pump problem change oil and filter and do a flush ---and put in an additive such as lukas - royal purple etc---also why did head need replacing was oil pump tested

High temp low oil pressure light comes on after driving for a few minutes, then off when engine at driving rpm. At stop light (idle or low rpm) light comes back on. Normal driving it goes out.


You need to find out why you have low oil pressure. It is normal that as engine rpm's increase, the oil pressure will rise- the oil pump is moving oil faster. Even though your light goes out, you could still have critically low oil pressure. There should be sufficient pressure at idle to keep the light off. The light will come on when your oil pressure is almost nil- I believe for some it's as low as 8 psi. Normally, oil pressure at idle is specified anywhere from 15 to 40 psi. You would have to check specifications for your Expedition. To verify oil pressure, hook up a mechanical gauge at the oil pressure sending unit on the engine block. Check with a local shop.

The causes run from easy, simple to budget busting ruin. Low oil level, wrong grade oil, real old oil, oil leaks, internal oil leaks, worn oil pump, worn crankshaft bearings. It was pretty common on older very high mileage cars to have a fluttering oil light at stops and idle. It was time for a rebuild, or time to look for another car.

1999 chrysler sebring low oil pressure at idle


It may be the oil pump. If the gauge is going up when the rpms increase it's probably not the gauge or pressure switch. If the computer senses the oil pressure is low it will shut the vehicle off to try to save it's self from catastrophic failure. Also it may start cranking longer before starting. Thats it building oil pressure before the computer will let it start. Make sure oil is full, clean & thick.

Oil light with a line underneathe it, what does the light indicate?


Low oil, bad sensor, really low idle.
First check oil level.
then if oil level is ok, and oil light is still there, pay attention to idle has to be 750 to 850 RPM.

If idle ok, give gas to increase idle to more than 2000 rpm if light goes away you need a sensor called OIL PRESSURE SWITCH.

Low oil pressure light is comeing 98xj8l jaguar


OIL PRESSURE SHOULD BE 70 PSI@4000 RPM 30 PSI AT IDLING. MAKE SURE OIL FILTER AND OIL BEEN CHANGED AND MAKE SURE OIL LEVEL NOT LOW.AND YOU USE THE RIGHT OIL.IF ALL IS GOOD OIL SENDING UNIT COULD BE BAD.

94 f350 7.3l turbo diesel looses oil pressure as rpm increase


Before you spend money on a new gauge. Get an oil pressure testing gauge for $20 , remove the oil pressure sending unit and test the oil pressure. If oil pressure at idle and 3000 rpm's is a-ok via spec's ( big money repair items) then its either the gauge a clogged or defective sending unit or the circuitry. (little money repair items)
You can also have this done at a repair shop.

Oil pressure guage pushes to 80 when not idling.


In an engine in good condition, oil pressure is a function of RPM. Higher rpm, higher pressure. Whne coasting downhill, in gear, the engine rpm will increase, hence, the oil pressure will go up, as required, and as expected.

There is nothing wrong with your engine, unless the oil pressure goes excessively high under any regime. Low oil pressure is a sign of low rpm, or under load, a sign of worn parts.

1991 300zx low idle, and low oil pressure!!!


650 to 700 rpm is ideal for the 300zx. the 300 was meant to be a performance car used at the rpms of 3000 and 6000. i have a 91 300zxtt that i use as a race car and a low idle is never really a bad thing as long as it isnt searching or loping
