Hi Colvert,
You're right. Suppose that's how this thread ended up in a 43-pager :-)
Anyhow, I did find out the source of the leak. My 75 was afterfitted with an LPG installation. Apparently whomever installed it one day thought it was a good idea to pass the control button wiring of the lpg kit through the plenum to below the dash on the driver side. I suppose the hole he used is one of those mentioned that should have been fitted with a rubber bung originally (clearly was a factory made hole, even had a hole foreseen in the plastic cover beneath the dash). Man in questioned decided to seal it all up with an inefficiently supplied plug of silicone kit. Remainder you can guess from there on..
