Well I hope I didn't violate any local obscenity laws, but I just did the
servi- er, experiment on the pressure cap and I got no particular resistance
in either direction, so I guess that answers at least that part of that
question. Did a fair Darth Vader impression, if you can imagine Darth Vader
with pneumonia.

No caps locally, but I have plenty to do while I'm waiting for an order. : /

Cya,
Robert

Well, my theory is ... the valve is rather unsophisticated so that when
there is little pressure (like when I had the nose in the air and
gravity let coolant get past) it doesn't seal well like it does when the
system becomes pressurized.  That said, I'm sure some seal better than
others (under low pressure) but still do their jobs.
