Anybody have experience with a failed Suburu Head gasket.
Milo was on the way from Washington to Texas and made it as
far as SZP. Then the Soob engine had a mysterious over heating
problem towing a trailer.

No experience with Soob and blown head gasket, but with a Dodge Minivan, I
had an overheating problem that seemed 'mysterious'.

It would overheat, and when you checked the coolant reservoir it would be
full. When the engine cooled, the reservoir would go down as expected.

The problem was a small leak in the head gasket, which would put combustion
gas into the cylinder space, driving the coolant out of the engine and into
the overflow reservoir.

Bill, did you try any chemical sealants such as duraseal or steel seal?

Paul Lamar

Yes I have as that is my business and I rebuild 3 to 4 engines a week, no
none of those sealants will work as the problem is the combustion pressure
is pushing past the gaskets into the water system and pushing the water out
the burp tank and so there is no way to plug the leak unless you could get
the sealant into the combustion chamber to shove it into the hole thats
leaking, hate to say it but you are best to go for a whole engine as you can
mill the heads when you replace a head gasket but you cannot mill the block
and the block warps as much or more than the heads so if you put a new
gasket on a straight head and a warped block it wont last long, I can do a
compete long block for $1500 to $1600 depending on which engine it is and I
fix all the problems that Subaru had to make it better than new.
Give me a call if you need more info.
