Hey guys im in need of some help and im hoping you guys can be of assistance. My uncle has a 01 XK8 and underneath on the driver side of the throttle body there is a coolant hose that has a serious leak. and the only way i can get to it is to remove the throttle body. i can see maybe 6 bolts to remove it but is there anything else i should be aware of?? just lookin for some info before i start taking it apart. any info,experience, or pictures help! thanks.

I used a couple of old Duracell AA batteries which were just the right diameter.

I recently did mine and took photos. This link should help Jaguar XK8 Throttle Body R&R
Had to smile when I saw you'd also used Duracell batteries to plug the hoses!

You might get away with it but best to renew as you certainly don't want air leaks at the joint. Metal gaskets compress as the fixing bolts are torqued up and aren't intended for reuse.
Part Number is:
NNE 3021 AC - XK8 Throttle Body Adaptor Gasket
I paid £5 in November 2011 so expect around $10 with the difference in parts pricing structure between UK and US.

If so, you can either buy the proper tool (the one with the purple handles in Gus's illustrated guide) or use a large pair of pliers to pinch it but watch out for your fingers as you take the tension off because they're tougher than they look.

well turns out the metal gasket is allowing air in. i though i could get away with reusing it but you can hear the engine wanting to die out and also hear the TB sucking air from around it. oh well it was worth a shot. im calling parts stores around town to find one, but i may end up getting it online. should i put some kind of silicone on when i get the new gasket? also is there a tightening sequence when tightening the new gasket to TB?

2. nothing on the NEW gasket
3. do all the four nuts up hand tight and then torque to 21Nm
I tighten diagonally but it probably doesn't make much difference.

got the throttle body and everything straightened out. after the work was done and the car started everything was fine and running smooth. the check engine light was on so i pulled the codes and it was saying there was a misfire in EVERY cylinder. but it doesnt make since because the car is running nice and smooth. it even passed smog! idk it was strange.
