I have not heard the results of the CSI comparison yet, either, but I used the Ford primary and secondary tensioners and chains and they were a perfect fit in both the '99 AJ26, and now the 2000 AJ27 installed in the '99 car. They seem to be working fine, although I am still working through the compatibility issues with the new engine and have not had it out for a good hard run. I don't suspect they will present a problem.

 

I gave them my vin number and I am under 80k and he said it would be 96.00 bucks to get it done. Im talking to another certain ford dealer employee about it also. I will find out more when I get back in town next week.

 

Does anyone know if the valve cover gaskets quoted earlier in this thread (see below) also fit the Jaguar 4.0?

Yes, they do.

 

Just thought I would pass along that I picked up the full Felpro Gasket set (FEL-PRO Part # VS50724R ) for the Lincoln LS, fully compatible with my 2001 XKR for $39.79 from Rockauto.com.

Quality and fit seem excellent. This includes both L & R valve cover gaskets, spark plug seals, and a full set of grommets. Pretty decent deal.

 

So far, I have seen a lot of info on changing out the secondary chain tensioners. Has anybody done the primary chain tensioners in the DIY fashion?
Particularly, I would like to know if I could just unbolt the old tensioners and put the new ones in their place without loosening the VVT, secondary chain sprocket, taking out the guides, using shims, etc.
If not, I suppose I will have to rent the timing tools off eBay.
Thanks.

The tensioner section (alphabetical) has several links to DIY discussions and pictorials.
