I just bought this car for $300..
After some basic repairs on it, I found that the cooling system becomes pressurized too above 13lbs, as it can blow the cap right off the car when I try to take it off.
This is only from cranking..

The car has a very hard time starting and once running expels all it's coolant.
My RX-7 knowledgable friend suggests that the coolant seals are bad, and the engine has been overheated, causing exhaust gas to pressurize the coolant system.

Does this sound logical?

yep, blown coolant seals
