Calling Tim S,
Going through this 4440 column and valve: new thrust washers, bearing, bushing, and seals. Valve itself seems ok, leak appeared to be between the column and plate/valve. Upon removal & disassembly I think I found the cause a booger weld fix to a broken column pivot mount that was not ground down and did not allow the plate & valve to mount flush to the column. My question is the tech manual shows no gasket between the valve, plate, and column. Should I put gasket rtv or copper spray when I reassemble? I fixed the booger weld and flapper wheeled it smooth but that not precision leak free surface.
