How does this kind of bleeding screw work anyway with just one nut on it?
This recent post by Bob explains it best (http://300mclub.org/forums/viewtopic.php?f=49&t=27482
This is what it should look like.
Hole in the side is connected to the hole in the top.
nothing inside, no check valve nothing.
When tightened into the hole the tapered end (left side of image) seats inside the aluminum housing of the lower intake and stops the flow.
There could be some trash between the seat and the bottom of the bleeder that is preventing complete shutoff.
Or someone (perhaps a previous owner?) could have overtightened it, damaging the threads, or breaking the bottom of the seat out of the aluminum intake. The bleeder only needs to be snugged up, not torqued like a regular bolt.
Remove the bleeder and inspect it for damage. While it's out, see if there is something stuck in the seat - or if the seat is missing or broken and dropped down.
