Hello.

I'm new here. I'm in the process of getting a 1987 XJ6 Series III up and up for my sister-in-law. Car appears to be all there.

Here's a breif summmary:

Silver, auto trans (not sure if sticks were available), sunroof, power windows, door locks, mirrors.

I know the forward catalytic converter is bad (already id'd that).

There appears to be a problem with the heating / air conditioning system (has a mind of its own, both cold and hot work).

Hood latch on driver's side doesn't stay latched

Oil leak near rear of engine (rear main seal?)

Other than that, car appears to be solid.

I'm going to order a shop manual from Moss Motors (unless someone tells me a good reason not to) as they are relatively close to me.

Thanks in advance for the assistance!
 
Autosteve, The 87 XJ6 is one of the better Jaguar sedans made and deserves to be taken care of. The equipment you describe was standard and there was no manual transmission for Nortdh America. If the AC system regulates between cooling and heating depending on temperature setting the expensive parts are OK. (the servo and the servo amp). The "mind of its own" is probably a fault in one of the sensors that regulate its performance. The regulating system is very unique to the series 3 XJ6, if you can get someone who has experience with it, use his expertise. A simple adjustment of the hood latch or actuating cable will solve your bonnet problem. Now for the bad news (maybe). Either the oil leak is coming from the rear of the cam covers, some oil lines on the rear of the head to block interface or from the rear crankshaft seal. The 87 model had a problem in the crankshaft journal alignment and there was a factory recall. I doubt that it is covered after so long a time. The dealer should have caught it under warranty years ago but many of them welched out of the fix. The cure is not simply a new rear seal. The block must be removed from the chassis and the journals line bored to correct misalignmnet and then resealed. Then the problem goes away. Installation of a rear seal only will not last long and to properly install it the engine must be removed anyway. Hope this helps and hope that it is a cam cover gasket!! Best regards Jack Farrington.
 
Thanks for the particulars. One of the nice things I noticed on this model is that its got Bosch fuel injection in it.

I'll have to look into the leak. There is a chance that my brother-in-law overfilled the crankcase and afterwards it was parked on an incline. I've degreased the block and not it's wait and see for a reappearance of oil.

Keeping my fingers crossed.... /ubbthreads/images/graemlins/thirsty.gif
 
I don't know if the manual from Moss is what I am going to describe, but here goes.

There is a CD available from JDHT (Jaguar Daimler Heritage Trust) that is available either direct or through various vendors. This is the factory sevice manual that the dealers used. It has all the procedures as well as the factory parts book.
