Jaguar V8 engine questions/concerns

[fast cars]

I am about to buy a jaguar xj8 that's only done 44k with fsh with main dealer??, I have just read about problems with timing chains, tensioners and nikosil liners?? The owner does not know if anythings been done as he has only owned for 1 year. Can anyone steer me in the right direction ?
Thanks
Danny
