The EBC8709 o-ring, part 6 in the diagram below, is apparently no longer available. This is the o-ring that seals the neck from the supercharger air bypass valve.

Some of the other o-rings in the XJR6 intake tract are also NLA, and I have them handy to measure, but I'll have to take the intake apart to pull (and likely destroy) the EBC8709 to measure it.

So, any chance someone knows the specs for the EBC8709 such as inner/outer diameter, gauge(thickness) and material?

The Jaguar Enthusiasts Club is/are having meetings with Jaguar/Jaguar Classic Parts to talk about parts that are no longer available. It would be interesting to let them know of such parts.
