The heater contral valve dribbles a little on start-up but seals as the engine warms. A dozen drops at most. Toyota has discontinuted the part. Anyone have a fix or clever replacement that uses the stock heater control cable? Hope all is well.
Your right, the heater valves have been discontinued for a number of years, but I do have a brand new OEM Toyota still in the bag valve for 76-78. If interested I would take 75. for it which is about what they were when available.
