Scott replied the topic: Re: ZERO DRAG SEALS
ALL the brass insert type zero drags seals leak a small amount ... Just some wetness around them really.
** Because zero drag seals are ZERO CONTACT with crankshaft, NO physical seal is actually made, but instead seal by being VERY close too the same diameter.
Do note however that seals can wear out VERY QUICKLY if installed crooked, or crank has excessive run out from being bent out of alignment.
