If you loosen the oil fill cap on these cars they run very rough or die.
I think that is the only reason why your car was running poorly.
I do not think there is anything wrong with your car.
It is true that a crankcase with no airspace at all is bad, but I think your crankcase probably still had plenty of airspace in it and no engine damage has occurred.
How is it running now? __________________ ...
