It appears maybe I should have been more concerned. About 220 miles into
the trip coming up a steep hill in 90 degree weather the car overheated very
quickly. I started losing power and when I depressed the clutch, the engine
totally stopped. I pulled over and lost about a gallon of coolant. Waited
a while and then filled the radiator again. Car heated up a couple of more
times, but not as bad. Then white smoke started coming out of the exhaust.
When I stopped I noticed that one of the dashpot plungers had come loose and
there was oil on the firewall behind it. I am not sure what that would do.
I replaced and tightened it, but still white smoke. It also occurred to me
that I dropped 2500 feet and that could impact the carb adjustments. I can't
remember if elevation loss leads to leaner or richer running.
The other thing I noticed was that there was a significant amount of smoke
coming from the oil cap vent. What does that signify.
I was running 10w40 and couldn't find 20w50 at any of the gas stations along
the way.
Car made it and still runs, but I am afraid I may have done permanent
damage. Rings?
Thanks,
Jeremiah

Screwing it in (clockwise) can / should increase the pressure,
screwing it out will decrease the pressure. If it's screwed in all
the way, that fight's been fought already. As someone else said, you
may have some debris in there preventing it from closing all the way.
Sounds like the pressure is maintaining - finish the trip and deal
with it when you've got tiem.
