I have had a similar problem with FG 8659 recently, but on the stud between Nos 1 and 2 cylinder. The car was running well otherwise. I checked he nut on the stud in question and found it was barely finger tight! So I checked all the nuts and made sure they were down to 25 ft/lbs and carried on motoring on the basis of "If it ain't broke, don't fix it!"
