Does anyone know if the links provided for the DIY tensioner fix can be updated? I'm getting an error with each link (I know they're old), and am looking at a few XJR's to purchase that likely will need this done. I need to decide if I'm up to snuff on the job, or if I will pay someone and factor it into what I negotiate for price I'll pay for the car. And let's just say I'm not the best mechanic. Any help is appreciated! Thanks!

I had mine done by a professional, but some members here have gone the DIY route. Average cost of replacing the tensioners today is $1100

 

Or about $200 DIY, gaskets included.

 

Well, just to throw my 02* (what happened to the cents symbol ?), I replaced my secondary tensioners shortly after I got my car and the left one (drivers's side here) fell apart when I took it out. They were both split up the middle. This was at about 70K miles, FWIW. Point being - this is not a thing to put off.

 

You certainly do not have to be "the best mechanic" to successfully change your tensioners, but you do need a reasonable box of tools, and patience and a place to work. If you use the zip tie method, and mind the tightening sequence after carefully getting the cams to a no low load position before starting, you should be fine. Just plan the work and stop and think or ask questions before embarking on any of the steps you do not understand the how, what or why for. As noted, It can easily save $900.00

 

I was quoted $1660 by the dealer; $1330 by the best local specialists. Spent $140 for the new tensioners, gasket was still good; used a battery powered screw driver for the tedious wrench turning; was super careful with removing and retorqueing the caps - 4.5 hours. As many have noted getting dipstick out of the way was the hardest part (cut a slit in the retainer with a hacksaw). Before I started I read everything, best advise was a statement that patience is the best tool in your toolbox.

 

just secondary tensioners while you are in there water pump and thermostat as well

 

Thanks for the inputs, everyone. The arrogant engineer in me says go for it, but the conservative account in says I'll do more damage, and will eventually cost myself more money if I #($*% it up. I'll keep doing my research, and use this info to select/negotiate the right car. Once I finally lock on one, I'll probably annoy you folks even more!

 

fwiw, I finally worked up the nerve to take off the cam covers to check. Wasn't bad at all, even the oil dipstick just pulled up and off. didn't have to disconnect any of the water lines, they just laid out of the way. other than the right size (10mm?) sockets, the only "fancy" tool I needed was a u-joint socket thing to reach the back lower bolts on the cover. I did end up with an extra bolt from the air cleaner box (i think).

 

rule one: never, ever, have parts left over . . .
