I've got everything cleaned up and ready to go back in the car (1999 XJR) and noticed the workshop manual tells me to replace the rubber seals on the 4 bolts securing the outlet (I'd call it a cover) for the SC.
I found the square seal the seals the outlet to the SC but can't find the bolt seals.
Does anyone know the part number for these?

 

I think they are the same for the CAM COVERS (isolators) but it has been a few years since I sourced the parts.

 

Where are the rubber seals? The only thing I remember is not replacing them.

Edit: I went out and looked, they're between the top flange and body of the outlet plate; still never replaced them and they're working fine after 24 years.

 

I have not replaced them either. Two times removed sc so far.

 

Me three! Seemed like they were fine to reuse?

Just like the cam covers, the isolators provide the 'clamping-force' to the cover. When the rubber gets compressed, the machine screw/flange assy does not press down as hard.

 

As I'd already cleaned all the parts including the hardware I decided to look these seals over closely.
They still felt like rubber (unlike the o-ring at the bottom of the brass quick connect for my brake booster vacuum line) and they didn't have any indentations related to the upper flange of the sleeve that goes around the bolts securing the outlet for the SC.
Everything is back in place and all the coolant hoses are in place and hooked up at the front of the engine.
Unfortunately I broke the fitting coming out of the left hand heater hose passing under the SC so I'll have to order that and get it in place before the mechanics behind the engine are back in place.
Just when I thought I'd turned a corner!
Oh well at least it was a nice day to be out working on the car...
Thanks for the input everyone!

 

You're the first one that's broken that nipple off.
