I know that some head gaskets can and have failed suddenly, but in my experience this is on vintage or racing engines. And I know that for a decade, the Subaru EJ model 2.5L engine, which I have, was notorious for developing a slow head gasket leak due to movement of the cylinder deck.
But I would be curious to know if anyone in the forum has heard of a Z3 engine whose head gasket suddenly and completely failed and blew out the coolant in a trail of steam.
