That would be cool.  I don't understand the whole vent thing, really.
Not too long ago I replaced some caps in some 80s vintage Yamaha gear
(one stereo receiver, one synth).  Both pieces had caps that had
apparently vented and spewed uncleanable (by me, except by chipping)
but apparently harmless crud onto the PCB -- but the gear still
worked.  No explosions.  No hosage.  Well, the receiver had been
suffering from intermittent problems for years, but when it turned on
it stayed on and worked.  So what's going on with this venting?  FWIW,
I replaced them with the highest lifetime parts I could find -- and
for me, form factor was a big issue.

Tom.
