<p>oh come on.... there are many 'no seal' metal on metal, even
glass on glass that do not leak!</p>
<p>Many of todays modern rotary lever sink faucets have no o-rings
any more. They are simply flat ceramic wafers when you align the
holes water flows. An that is a much higher pressure than any rad.</p>

<p class="MsoNormal">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).<o:p></o:p></p>
<p class="MsoNormal"><o:p>�</o:p></p>
<p class="MsoNormal">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).<o:p></o:p></p>
<p class="MsoNormal"><o:p>�</o:p></p>
<p class="MsoNormal">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.<o:p></o:p></p>
<p class="MsoNormal"><o:p>�</o:p></p>
<p class="MsoNormal">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.<o:p></o:p></p>
<p class="MsoNormal"><o:p>�</o:p></p>
<p class="MsoNormal">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.<o:p></o:p></p>
<p class="MsoNormal"><o:p>�</o:p></p>
<p class="MsoNormal">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!).<o:p></o:p></p>
<p class="MsoNormal"><o:p>�</o:p></p>
<p class="MsoNormal">Hope that solves the mystery.<o:p></o:p></p>

<p class="MsoNormal"><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.
