To do the timing chains properly would cost just over $2k. That would renew all chains, guides, and tensioners. If the chains fail, you could be looking at a new engine. It is a big deal, but once the tensioners are updated, these are very solid vehicles.

Search the XJ8 or XK8 forms for tensioners. You will find more than you probably want to know.

Try this link for tensioner information:

https://www.jaguarforums.com/forum/s...ad.php?t=20092

Look alphabetically for 'tensioners'.

The secondary ones are the ones that most often fail, and take the entire engine with it. Most only replace the secondary ones. About $1000 at a dealer, $800 at an independent, about $200 DIY. Plenty of information and pictures on how to do it.

It is not a difficult job. While an experienced hobby mechanic, I had never done that work and finished in 4 hours while detailing the engine.
