I just changed my own timing chain tensioners........HOW TO

Ok, maybe I'm being paranoid, but I just read in this article about the early 4.2 V8s requiring tensioner changes. I knew this was a problem with the 4.0 engines (been there, done that with my last car, an XK8), but is it necessary to do the tensioners on the newer engines too? Please say no....
Would have thought they fixed this problem with the introduction of the new engine.

I got an 02 XJR and unfortunately had the plastic ones, replaced them and man it feels so nice to know this engine can purr without the worry of tensioners failing anymore.

I mean if the tensioner issue has been fixed by Jag on newer cars, why worry, what else is there to do, you have an 03 with metal tensioners, relax and go in peace.

12 years - yeah, I'm not worried about expecting things that might need attention after that much time, but whether or not what that article said about tensioners is even true - were they plastic or metal tensioners? I'm surprised to hear the 02 variants still had that problem, but also I'm not sure when Jaguar recognized there was a problem and issued a TSB.

I'm glad you confirmed this, I asked when I first purchased my 02 XJR about its tensioners and was told to quit worrying that it had the uprated tensioners because it was an 02 (which I was pretty sure could still have plastic tensioners). Your admission is all I need to know, when the old s/c comes off the valve covers are coming off too.

I have spent hours today reading threads and searching parts. I have landed on the following kit, to which I will add an aluminum thermostat housing and water pump. Please advise me; is this kit good quality, good price etc.?
Thanks much,

I noticed that Barratt, Chris, DCR and jag-bits all supply after market parts. Any comments on the quality of these, in comparison?
Thanks for the advice.

Why could'nt you remove the cam bearing tops so as to lift the cams up from the back and tilt them forward....remove the old tensioners and install the new ones.
If you did that and did not remove the chain from the sprokets, then no need to lock them down.......just replace the bearing caps and re-torque ....?

Yes, I pulled up the outer cam and replaced them that way. On the inner cam, wedge plastic or something inbetween the cam chain and the head so the chain wont move. On the cam you pull up, the gear has some slots. Put zip ties to hold the chain in place. Lift, change tentioners and replace. Make sure flat spots on cam are where you were when you started and wala, yo are done. I have done 3 of these engines this way so far.

Jagbits, will loan you the installation tools, free of charge if you purchase the parts from them. I personally did not use them when I did my ‘97 XK8 , BUT, if I had known about that , I would have done. It’s not any big deal to rent the kit from a Jag parts supplier, and courier them back when you’re finished with them. I would not hesitate to use the correct tools for the job. It’s a walk in the park if you choose to use them.

Seems beyond steep. How many hours labour are they quoting? Just looked back at the writeup I did when I did mine many moons ago. I'm not current on parts, mine cost USD 535 but I think today they should still be well under $1000???
Below is pasted from my writeup
"The total job took about 13 hours to complete which exceeded the shop time by a few hours. Most difficult was getting the harmonic balancer off. It took a couple of hours as the puller I used was fairly long which made getting it on straight in the space tricky. In all, 10 hours were spent removing and replacing components necessary to access the tensioners and rails.
I built a couple of cheap & cheerful tools for the camshaft sprocket removal based on pictures of of the Jag tools shown in AllData & using measurements I took from the engine. Time to create them was about an hour (included in the 13 hour total time) & they worked fine.
The tools I made to complete the change. Cheap & Cheerful and worked.
