I agree with Station X with regards to Blue Hylomar, never had much success with it. I have used gallons of Wellseal over the years and still do mainly on newly machined (mainly Rover) aluminium cylinder heads. Wellseal is non curing though so whether this makes any difference I don't know.

Loctite 5910 is what I would recommend, around 10-12 quid for a small tube, expensive, but you get what you pay for, other sizes are available. If you observe cleanliness prior to application and observe curing times its excellent.

Regards, poppydog.
