Thank you Jaguar Forum and member Larry Loutan, I have spent this summer repairing the #6 cylinder exhaust valve leak and restoring the car in general. Larry Loutan of Venice, FL has helped me with his 95 XJR knowledge, tools and new parts - could not have done this repair without his assistance! When I got the timing chain cover off and removed or tried to remove the two 6th cylinder exhaust valve springs, found the last one = #12 exhaust valve assembly had self destructed bending the valve shaft and the bucket. Had to weld a bolt on the bucket to pull it out it was so deformed. With that diagnosis, Larry offered me his brand new, in the box, numbers matching 95 XJR cylinder head with cams and the associated gasket kit. He walked me through the head removal, new head pre-oiling and installation. Timing an XJ6/XJR after head replacement is a once in a lifetime experience! The repaired XJR motor runs great and I have been repairing other problems that showed up once it was running - i.e. check engine, ABS and Track-fail lights on dash. Airbag light still on and working on that diagnosis shortly as it is not connected to the ODB II system? The oil pressure transmitter was malfunctioning showing 0 oil pressure and my oil light coming on at a stop light so, replaced it with a new one and now have reasonable oil pressure readings. I am finishing up repainting the hood, roof and trunk lid which had sun damage from the Florida sun. - then its just nits to finish this restoration = radio antenna operation, is the CD player working?, rear brake job and finding a 17 in Jaguar wheel as mine came without a spare wheel/tire?


Anyone know where I could buy a 95-97 XJR 17 in wheel?

 

Sounds like a thorough job.

I made a document some time ago describing how to diagnose the Air Bag system which may help. You can find it here.

Larry already sent it to me. Thanks for putting it together. He recommend I stat with testing the clock spring as the most likely point of failure?

 

You can't really start with the clock spring test. By doing that you would be bypassing two components in the circuit and would not know which one was causing a problem. I'd suggest you start with the Driver Air Bag as per the document.

I have seen issues where just unplugging and re-plugging the Air Bag has cleared a fault.

 

Brendan, that is very helpful advice on debugging my airbag system. Thanks for your information!
