I purchased a 1998 carnival red xjr 48000k in 2003. I adored this car and the many extras I added for a xjr different from the rest. 18 inch jag 5 spoke replaced the center caps red to match the car. Purchased 4 more red centercaps peeled off the brackets an installed on every seat in the back rest 4 inch tv where the sunglass holder was and a system without changing any stock items no subs in the trunk 1 behind drivers seat just for anice touch of bass. alot moreinvested tolist in changed low beam, high beam, fog and parking to blue lights looks mean and serious head turner. this my 3rd jag i had a 91 xj6 and a 95 xj6 and might consider a 04 xjr

oil pressure by johnwesley1

Help. I also have a 1991 XJS v12 mine also loses oil pressure after it gets up to normal operating temp. not going down the road at say 55mph but if i slow down to 30 or so mph it drops to below 25 lbs at a stop sign or stop light it falls to 0 then as i get moving again it comes back up. The temp gauge says normal operating temp. althought the engine seems to be hotter than normal. It does not die or its not hard to start at all. My question is rather than pays a dealership alot of money to tell me nothing may or may not be wrong with my engine i would rather just install a set of after market temp, and oil pressure gauges so i can be sure of my oil pressure and engine temp. can anyone tell me where the oil pressure and engine temp sending units are so i can disconnect them and install the after market gauges. thank you for any info. you can help me with

The gauge must be inaccurate. If your oil pressure was actually zero, you would certainly be the first to know about it.
 
Are you using an OEM filter and the proper weight oil?
 
My books don't go back that far to locate your oil sender but surely the person who works on your car would tell you?
 
OH WAIT! I see a diagram. It looks like it is between the V of the engine, up front, and there's a long hose arching over it. It's a small round cylinder with a wire attached to it that screw in.
 
The book says:
 
12 cylinder:
Open the bonnet.
Disconnect the battery earth lead.
Disconnect the rubber boot and the transmitter feed wire.
Unscrew and remove the transmitter
Fit and tighten the new transmitter.
Reconnectthe transmitter feed wire and the rubber boot.
Reconnect the battery earth lead.
Close the bonnet.

Well that sending unit is over $100, so you might not want to be guessing. At the very least, I'd be more inclined to pay a mechanic $100 to screw in an accurate mechanical gauge and tell you what's what for SURE. The aftermarket gauges aren't very attractive, after all, hanging like that under your dash.

Depending on how good the parts stores are in your area you might be able to borrow/rent/lease a mechanical gauge from them.
