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.
