Radiator Air Valves

When replacing a radiator air valve, should one use pipe dope, Teflon tape or nothing at all?

    I find that you really don't need any sealant.  But if you must, stay away from teflon tape because you do not want to get stray flakes of teflon to find its way into the valve mechanism and cause it to fail.  A very small dab of pipe dope is all that you really need… If you must. Bottom line is to keep stuff from entering the valve opening so it does not get in there to foul the mechanism.

    After you make that expensive repair and you still have the same problem, What will you check next?
