Hi guys,

I may have had a catastrophe today. I was driving along the highway and something in the cooling system blew open. It's on the exhaust side of my 1990 M20. It shot coolant at the exhaust manifold and stunk up the cabin.

I couldn't see any hoses on that side. What could blow out like that? Could a headgasket blow externally? The car still ran fine and I managed to limp it to a nearby parking lot before having it towed.

Thanks,

Mark
