X300 XJR Questions

[Antharro]

I'm toying with the idea of buying an X300 XJR, 4.0 supercharged. I love the design of this generation of XJR, but I have concerns. Mostly about the nikisil problem; I've read that any cars surviving now will have either had an engine swap (green tag on the engine) or will be nikisil engines that weren't affected badly enough to be swapped out, and should be OK now as nikisil hardens with age. I understand a blow-by test (presumably done by Jaguar or a specialist) can identify problems here, so definitely worth doing. I'm concerned that I'm going to end up buying an expensive repair bill.

I've also read that this generation can sometimes require major suspension component replacement (bushes, shocks, etc) as due to its character it will have been driven hard and therefore these parts will have worn faster. Is this at all likely?

Last thing is to apparently look at the frame by the front shock towers to check for rust.

Is there anything else I need to know about, or any advice you guys could share?

Thanks. 🙂
