I am new here (great site) have bean searching here for info on tensioner guides and parts(2002 XJ8) lots of good info out there. looking for best price on primary guides (jag V ford) secondary tensioners (jag V ford) and part numbers, if I use the third Gen primary guides do I have to use new chains. maybe someone has posted this info allready but I can't find it. Thanks for any help. Rob

 

The best prices for timing components I have found were on ebay. You will also need to rent or buy the tools that are needed to do the job as well. Sometimes you can re-use the chains. I compared my old ones to the new ones and found no difference in length. I still put the new ones on though...

Also, if the plastic cap has slid off a secondary tensioner, that means the secondary chain is riding metal on metal. In my case, the chain had been worn down by it and definitely required replacement.

 

I haven't heard of primary chains going, so you an do the zip tie method and save $$. Best price I have found is my local small parts tore $85 each for the secondary tensioners including tax.

 

The chains are not what go, its the tensioners or guides. I elected to do my whole system because the primary guides were cracked really badly. Take a peak in there with a flash light or bore scope, if you want a closer look, and inspect the guides. If the primary guides and tensioners look good, then I agree with the above, doing the zip tie method for secondary tensioner replacement is the better option.
