Yo it''s cool. My mechanic here outside STL, MO did did both sets in 6.2hrs total. Turns out, as busted up as my primary tensioners were..I just needed new tensioner''s, guides and blades. and all is perfectly silent. It obviously got hot a couple times and cooked as you can see from the sludge on everything, probably from when I had my water pump go out when I first got it. (getting that cleaned out).
Not pictured, but the right primary was also shot and badly cracked as well.
My opinion, best site for parts is http://www.motorcarsltd.com/ Gotta get those pesky jag tools for this job as well. Give them a call, instant responses.
Anyways, I was curious if the techs here can confirm this, but when these engines get hot can they crack valve covers cause they''re molded plastic? I''m assuming overtightening can crack them as well, either way my left valve cover had a couple hairline cracks around two of the mounting holes. At high RPMs it would spit out a little oil and have a faint smell for a bit outside the front left side of car. I really didn''t think that much of it at the time, it was so faint and was only there after high rpm bursts.
After this job and reassembly the cracks must have gotten worse, and actually split enough to push oil through andl burn/smoke.
Ordered a new Left (driver''s side) valve cover from the dealer, lists $233 here in STL, they have to get it shipped in, wait is 4 days. Been 5 days they still have no called. Will report when installed and tested (juiced hard!) :)
Labor alone for me was $700 flat for both sets of tensioners, no clue on Jag dealerships. Goodluck bro
*I have tools also i will be selling, so let me know as well.

Sure did.. who would have thought pieces of molded plastic would cost so much hah.

Anyways I got my updated valve cover, not suprising it came with new revisioned oil cap as well on it, so score ;) this one (valve cover) looks a lot better made than the original. Let''''s hope this does it.

btw I test drove an XF, couple 07 xj8s, and an aston martin DB9... that thing kicks serious ass!  the Jags are a LOT smaller in person hah.

EDIT: I still cannot post with my old ID, something still up admins?

Eh, after replacing the shotty 1st gen valve cover my leaks and smells have stopped. no oil, leaks, nothing. My sheet runs perfect, silent like it should. Last thing I am doing today is replacing the cheapo plastic thermo cap. $8 from dealership, wow. Thanks for the info.. it appears torquing to 9nm (80in LB) is vital for that cap?
