    if you only used boss white it will leak, you need hemp with boss white, or just use ptfe tape, no need to wait for it to go off

    sorry, thought you meant on threads :oops:

    a smear of boss white around olive will be ok to fill straight away, over the course of a few years it will harden and make seperating the joint difficult but not impossible.

    Do you use plenty of PTFE? I used to not use enough but was told by somebody to use 5 or 6 thicknesses (i.e. 5 or 6 times around a thread or olive). Works for me really well now in 99%+ cases.

    don't you just love em when they wrap miles of it around radiator olives and you've got to pick it all off when it leaks.
