Bought an XJ8 in 2003 low mileage 24k, my 2nd. Jag, last one was still going strong at 126K. Have just had timing chain break at 59k,Guy Salmon say 8grand to replace,I was in the dark until I stumbled on your great site, mentioning the nikasil and timing chain problems. Does anyone out there believe I have any redress or do I just put it down to bad luck or Jag being economical with the truth, whichever way I look at it , it has left me with a bad taste in my mouth! Incidentally at the beginning of December, after having starting problems with the car I had a 60k service at Guy S. telling them to do some kind of diagnostic to rectify the problem they said it was a sticky air inlet flap!
