It seams that all owners of the Lee Production pot IV is plagued by these little fellows, they are almost impossible to pick up.

I have tried cleaning, lapping the valve stem to the seat but the dripping always returned.
This weekend I tried another approach to solve the problem and it has been working so far.
All thats needed is a coil spring, a self tapping screw and a washer.

Fasten the coil spring on the opposite side of the valve stem with the screw.

Attach the other side of the spring to the washer and put the washer over the valve stem.

The finished product.
The spring tension holds the washer in place on the stem and pulls the stem in firm contact with the operating crank.
The spring also aids in a positive closing of the valve due to the downward angle.
Lets just hope that the heat of the melt don't destroy the spring characteristics.
I hope this setup can be helpful for someone.
