I'm not saying it's not the head gasket. I just know that cracked heads are a much more common cause in these cars.

Totally agree. Head gaskets usually don't leak on these cars. That said... this one is?!

I've done my homework... and I can convince myself that several scenarios are possible:
1. Did something crack and then loosen things up enough to create a head gasket leak?
2. Could the head gasket leak have reduced pressure and prevented a crack from forming?


Trying to figure out the best path to a solution. May contact Hoffman and see what they say if there is no great suggestions here!
