<div class="yiv0783023809MsoNormal">I can provide the definitive answer to this question because my company makes these aftermarket valves for Moss Motors (who probably resells them to everyone else in the world).</div>
<div class="yiv0783023809MsoNormal"> </div>
<div class="yiv0783023809MsoNormal">The response “they all leak” is absolutely correct. In fact, the problem is so pervasive and resistant to all attempts to solve the problem in manufacturing, that Moss no longer sells a functional valve. What they sell has no internal
drillings, it is just a plug. It is made to look like the original for authenticity purposes, but does not function (and hence does not leak).</div>
<div class="yiv0783023809MsoNormal"> </div>
<div class="yiv0783023809MsoNormal">If you disassemble one of these, original or repro, you will see that there are no seals. The “sealing” is accomplished by a tapered metal stem fitted into a similarly tapered metal body. The two parts are “clamped” together by virtue
of the external spring and depend totally on a very tight and concentric fit between the two metal parts. This valve was designed well before cars had pressurized cooling systems. And yes, they always leaked. But back in the day, before people started using
distilled water and high quality antifreeze with effective anti-corrosion additives, the valves quickly plugged up with corrosion and, voila, stopped leaking. When they were opened and reclosed, they leaked again, until the corrosion re-plugged them.</div>
<div class="yiv0783023809MsoNormal"> </div>
<div class="yiv0783023809MsoNormal">If you are dead set on trying to make one leakproof, get some valve lapping compound, disassemble the valve, and “lap” the two parts together for an hour or so, until the two surfaces are as smooth and concentric as possible. I have seen
this work on occasion. Basically you are perfecting the seating of the stem in the body.</div>
<div class="yiv0783023809MsoNormal"> </div>
<div class="yiv0783023809MsoNormal">If you just want to stop the valve from leaking and don’t care about the function, you can remove the valve and plug or solder the inlet port.</div>
<div class="yiv0783023809MsoNormal"> </div>
<div class="yiv0783023809MsoNormal">Jaguar used this same valve as a block mounted oil drain tap, with a bit more success due to the higher viscosity of oil vs. water. Several British motorcycle companies and Indian used this valve as a fuel shut off (and you can imagine
how that worked!).</div>
<div class="yiv0783023809MsoNormal"> </div>
<div class="yiv0783023809MsoNormal">Hope that solves the mystery.</div>

<div class="yiv0783023809MsoNormal"><span style="color:#1F497D;">Hi Brian,</span></div>
<div class="yiv0783023809MsoNormal"><span style="color:#1F497D;">Moss’s response to the leaking issue was “they all do that”. It’s been many years since I had this same issue. I solved it by taking the valve apart and polishing the parts. I don’t remember how I polished them,
maybe it was compound or 1500 grit wet/dry sandpaper. Some PTFE on the threads that go into the block or radiator also helps. Anyway, no drips since. I had to do this on 2 radiators.
</span></div>
<div class="yiv0783023809MsoNormal"><span style="color:#1F497D;"> </span></div>
<div class="yiv0783023809MsoNormal"><span style="color:#1F497D;">The other alternative is to use a “modern” petcock.</span></div>
