Having restored a few Jaguar MK2's regarding bleeding the clutch I never had a problem but my TR6 restoration regarding the bleeding clutch was a nightmare . I tried all the internet fixes but they didn't work for me. As a last resort I got the wife to keep an eye on the master cylinder for any air bubbles and most importantly for fluid going over the top. The fix was to remove the rod and the rubber gaiter from the slave cylinder. Let the piston come out to the end and then slowly push it back in as far as it will go. I repeated this approx a dozen times before there were no air bubbles showing at the master cylinder. Success at last. Hope this is of some use to other members.
