John:
There are two sets of seals. The first is between the bezel and
the instrument. These dry out. To replace these you must remove the
bezel and glass (twist and lift, as I recall). There are no new seals
available from the big three, so you must find a substitute of some
sort. A flat o-ring of some sort, or perhaps use a bead of RTV.
The second seal is a square o-ring that slips around the body of
the gauge and is compressed between the back edge of the bezel and the
dash when you install the gauge. These dry out and fall out, and are
often omitted by DPOs during maintenance. You can pick up set for $12 on
eBay from time to time, or roll you own by going through an o-ring
catalog.
Cheers,
Vance
P.S. Still using original gauge seals, but new o-rings. Waiting
for foggy instruments.

Subject: Foggy gauges
Question for the list. Whenever it is humid, the fuel, temperature,
voltmeter, and oil pressure gauges on my TR6 all
fog up. So much so that after it dries out you can see traces of where
the moisture was on the glass. Here in Ohio we
are getting into the humid/warm during the day - cool in the night
weather pattern, so it is happening even more when I
take her out at night. In fact, taking the car for a spin yesterday
evening, I noticed that even the speedometer and
tachometer were fogging up (that's the first time that's happened).
So here is my question. Is there some sort of seal on all the gauges
that could be bad? Is this just something that
you have to live with with our cars? I am planning on taking the dash
apart this winter to replace/redo the wood dash.
Is there anything I can do then to fix the problem? Any suggestions?
