Why the hell would an M112 engine blow it's head gaskets at such low miles? I know of a Crossfire with 230,000 and an SLK320 with 320,000 and they are fine.
In fact, we had FOUR cars at the 2021 Eureka Springs event over 150,000 miles and none had ANY history of any serious engine issues.


You SURE this engine has not been allowed to overheat in the past?

(And for crying out loud, don't even start the engine until this is resolved.)
