Well, what happenes is the crappo aluminum metal goes through a serious of expansions and contractions depending on engine temperature and weather conditions.
This constant expansion and contraction reaches a breaking point after so many miles where fractures appear in the flimsy headgasket on the block between cylinders. As you
know, the gasket is just a small sealant piece that is wedged between the head and block. Iron gaskets were more durable. In my case, my engine started running hot and
attempting to "overheat" where the needle would rise almost to the top of the temp gauge, then shoot down real fast. We discovered a hairline fracture where coolant was leaking out,
but thankfully not into the combustion chambers to milkshake the oil and ruin the motor. Thanks to Butch, and only $350 in parts, he stripped it down for me and gave me a lesson in auto repair.
That was Sept 2009. We got real dirty for three days, but I got a lot out of it.
