The outlet seacock on my heads seems to be leaking slightly, even though it's well greased. AFIAK, it's a pukka Blakes, with a conic insert held in by a plate with two bolts. The bolts are as tight as they can be without making the cock hard to turn.
The inlet side doesn't leak and the rubbing surfaces are nice and shiny, while the outlet surfaces are dull.
Can I grind the seacock in like I've done with engine valves? If so is valve grinding paste the right thing to use?
