I was out for a TR6 ride yesterday evening with She of the Strident Tones.
Upon noting that the cool ambient temperature required a little cabin heat
for her bare knees, I pulled on the knob leading to that miracle of
technology, the heater valve. Fairly soon after I noted steam seeping from
under the bonnet. With that keen intelligence that is noted in all my work,
I thought, "Ah ha, there was no steam, and now there is steam. Clearly I
have done something. I must do the opposite of the last thing I did". Since
the last thing I had done was turn left, I immediately turned right....
After having backed off of a somewhat red-faced gentleman's front lawn, I
realised that the second-to-last thing I had done was to pull on the
aforementioned knob. Pushing it closed stopped the steam. Ahh method, the
final result of 25 years of school. :^)
Further investigation reveals that the valve diaphragm is gone... again. I
swear this one has seen no more than 30 openings since installation a few
years back during the rebuild. What a design! Back when it was last
replaced, one was obliged to purchase the entire valve even if it was only
the $0.50 rubber diaphragm that was ruptured. What a rip! Is this still the
case?
