Having problems with your Jaguar XJ8 ?
1999 jaguar XJ8 secondary timing chain broke,is it for sure that some valves did bent? and if so, how do you replace them? is it nessesary to take the head off? or the valves can be replaced with out taking head off? Thank you.
The head must be removed to replace valves, also the replacement of these chains requires allot of special tools to align the cams, without them you will bend the valves again, and most likely if the chain came off at speed the valves are bent, the only way to know is to repair the chain and run a compression test on each cylinder to see if it has bent valves.. the last guy that i advised on this same job and model trying doing the repair without the special factory tools and no service manual and bent a new set of valves, trust on this, it is not a job for the home mechanic
