Yes, no issues getting either rear bolt off and the wrench cleared the intake manifold and the self ratcheting came in handy and made the job easier than expected!

Thanks Gus...I am getting the work done this week. Just wanted to be sure before I spent extra cash. Wish I had the time to do this myself but I am too busy making money to pay for stuff like this!

I've been a "light" mechanic for many years, a Jag owner for only 4, and a new member to this forum for only a few months and find it mostly very helpful. A broken pully, belt and resevoir hose led to overheating and an small leak from the therm housing onto the engine block on my 4.0 L XK8. I spent almost an hour trying to attack the two rear 6 mm bolts or remove the intake manifold which seemed so unnecessary if I could just get " the right tools"

After reading all your posts,, I was on my way to a welder when I stopped at a NAPA store. They sell a 8 / 10 mm brake bleader wrench made by Evercraft service tools, which is almost perfect for the job. It did break the rear bolts without modification of the tool and I used a curved long needle nose and a " cut down" 8 mm 1/4 inch drive socket for the rest of the rear bolt removal.

Based on other post info, I was going to re-install with the screw driver slot idea, but thien I found 2 6m - 1.00 x 20 cap screw bolts for the rear, and 2 6m 1.00 25 (same as original length) for the front bolts and installed them very easily with a 5mm ball hex driver 3/8 drive socket,, the ball end give you torque as well as a small angle for easy verticle installation. .... I hope these ideas help others in the future... and now on to fix the neg camber problem

NONE! I replace 2 of them with AL. The person who designed plastic for that application should be ashamed of himself.

That fits well with my philosophy of not fixing anything that is not broke.

I have crusting on my 2005 xk8 4.2 a replacement part is no longer made. I have searched any suggestions .

Thanks

Amazon lists a Chinesium one. Is this correct? It might be better than nothing.
