Re: I overheated my engine
MEtal expands as it heats up. A hole in metal, contrary to popular belief, actually expands as it heats up too. Aluminium expands faster than cast iron/steel, so it gets to the point where the pistons become to tight in the bore and essentially seize. Alot of the time the engien will run again once its cooled down, but often irrepairable damage is done- sometimes very minor, sometimes major.
When a car overheats, you usially feel it misfiring. I dunno what causes this, but it could have (probably) stalled due to missfiring before it overheated and seized. I think its worth finding out what exactly happnes (in general) to car engines when they begin to overheat- what causes the misfiring.
