Hi XJ81,

The outer edges/tops of the engine driven fan blades come into contact with the fan shroud, not the engine, when the engine mounts are no good. This is because the engine is either sitting too low, or it moves. The fan blades then hit the fan shroud.

Here is a pic of the fan, is that the kind of damage you were talking about?

Hi XJ4081,

That is the damage I was talking about. Our car had identical damage from two fluid filled engine mounts that had failed. The engine sits too low and moves around too much and the fan comes into contact with things it shouldn't.

Hi Starbuck,

what can I do against this? I could imagine that changing the engine mounts on a V12 is a bit difficult (and thereby costly).

Hi XJ4081,

The only thing to do is to make sure nothing has come loose that might be interfering with the fan, and check the mounts and replace them if necessary. Having a large engine moving around more than it should is not a good thing, and if not fixed will lead to other repairs being required.

Unless you are doing all of the work yourself you should expect some big bills when owning an XJ81. The V12 has some specific issues that need keeping on top of - this doesn't come cheap.

Hi,

in the meantime I have made progress: I had the steering readjusted (the first adjustment was done poorly) and now the steering wheel is centered, but the steering is still a bit nervous, the car runs after each and every groove. According to the adjuster, there is a bit tolerance in the front suspension arms/bushes.

According to my Jag specialist this is more or less normal, they would probably do another 100K km before TUV would complain, but it's not like new any more (of course after 24 years). We also tested the engine mounts (open the hood and do a little bit of braking) and they are clearly finished. So the next task will be to change the engine mounts - and when the front suspension is already lowered/out, we'll have the bushes/struts renewed, too. I hope this will also stop the steering wheel trembling, though I have learned that the steering column also has mounts/bushes that wear and that are even more difficult to change.

Finally I also found out what that strange noise is coming from - it's the radio! Who would have thought that, but when I turn off the radio that annoying whistling noise above 100km/h is gone. The specialist also gave me a kind of explanation but I already forgot it :oops: .

Best regards
Oliver

Let's get a bit closer to the original topic: (my Jag's) bulkhead. I wonder why nobody asked for it yet, since I made such a big topic of it :D . Today I tried to clean it and also get a bit more insight from the wiper housing, but I was a bit more complicated than I thought. I could remove the wiper arm without problems (did not need a wiper puller), but I did not get to see what I expected. There is a sheet metal beneath the upper plastic panel which covers almost everything but the wiper motor compartment which is pretty filled with the wiper motor, no chance to see the bulkhead from inside/behind without removing it all. But I was not sure how to remove the washer pipes from the jets (or if I would ever get them back there after I pulled them off) - and the wiper motor did not really look like it would fit through that cutout. Is there maybe a repair manual available from which I can see what steps are necessary? I think it would not be a good idea to put in the conservation fluid blindly, I could imagine the wiper motor would not like it.

Your bulk head is fine. Usually, rust develops just on the edge of the upper panel where it is overlapping the lower part.

You can carefully remove the hoses from the washer nozzles and then remove the whole cover. Wiggle the louvers and remove. Clean and dry out the bulk head. Seal lower seam with silicon (Sikaflex or similar). Wax whole space. Finished. Re-assemble.

The steering is always nervous at higher speeds. Replaced all bushes and more. Again: Live with it. It's british ;)

I believe Jaguar did not use enough seal between upper and lower bulkhead panel, you can see on the right and left section of my pic the seal is coming through - no rust - in the middle no seal visible, but (beginning) rust. I have only seen one 93/94 model in person that had no rust on the center bulkhead and there you could see the seal coming through even in the middle section.

So I don't have to remove the wiper motor? But will I ever get the the washer hoses back on the washer nozzles? There is not really much latitude to put my fingers inbetween.
