Hi Ed,
Just wanted to share....my 65 MGB does the EXACT same thing....the water temp
needle actually starts to move in to the oil pressure sector of the gauge!
I too have a new waterpump, rebuilt radiator, timing is correct, and everything
else to spec. I even run water wetter in the car to try to drop the
temperature.
This on a car that normally stays right on 190 degrees during "normal" ambient
temperatures.
My hypothesis is that the gauge is reading inaccurately. While I had the
"capillary" style gauge rebuilt by a credible shop a few years ago, I suspect
that
they are either very sensitive to ambient temperature, or they become
inaccurate at
the upper end of their spectrum.
I have a very hard time believing that the engine is THAT hot....it would seem
impossible for it to run at 230 degrees and not "feel" hot, not dump coolant,
and not ping....
Just speculating....
Cheers,
teej
