Your oil temperature gauge will often take 10 minutes to register a
change.
They are good to have but respond slowly to oil temp changes.
The CHT will give more immediate readings but it sounds like your wiring
has some problems.
Normal or preferred operating temps for CHeads is 350-450 with 450 being
the "beware point".
I rely mostly on my oil pressure gauge. My oil pressure at 70 mph and
200/220 degrees runs at 60 psi.
After working a long hill or fighting head winds the oil pressure will
drop as much as 5 psi before any other gauges have recognized or
displayed any temperature changes.
If you know your normals in ranges then just use your gages to alert you
to drastic increases that should be taken as Slow Down warnings.
If you find yourself passing through Dallas Texas in your journey, you're
invited to drop by for a visit, rest or mechanical assistance if you need
it.
