Heater control valve & spark plugs
Constantly bowing to the collective wisdom of the list, I'm beginning to
think WE ARE BORG!
Some time back there was a thread about heater control valves giving up
the ghost at inopportune times, especially long trips, and I in my
neurosis bought one. Never put it in. Yesterday, I did and as I looked
into the old one and pushed the activating lever by hand, the,what I
assume to be, internal sealing washer got jammed in the opening.
Happenstance? I think not. Another message from the Audi gods to perform
regular replacement of wearable parts on a 12 year old car.
The spark plug thread has been around for years. Spark always jumps the
shortest gap. Therefore trielectrode plugs insure a short gap, strong
spark because as the electrode wears on one terminal, another will have a
smaller(proper) gap and thus takeover until it wears, etc. I just changed
mine after 3+ years and yes the center electrode was no longer round,
looked like a Wankel rotor, but there were places where the gap was still
correct. Bottom line, I paid $3 each for new ones (John at Impex,
1-800-736-3550), with a rotor and cap the whole deal was less than $50.
Car is smoothed.
RESISTANCE IS FUTILE.
