Don't be to confident that in 2004 the headgasket problem ended. With my issue I had posted aways back about it, I had oil and antifreeze both leaking and mixing causing such a burning smell, It was caught in time anyways, it never overheated either so I was so glad of that. But then a couple months later I started getting really bad engine knock and the engine had to be removed, and I ended up getting a new shortblock and everything is now great and its so quiet! It was all warranty to, even better, and my rental was to!

thanks for posting, good reference.

 

sounds like a lot of the older EJ25's....head gasket and internal bearing issues later in life. not that rare, but i'd suspect subaru has attempted to make changes to alleviate these. be nice to know what that is exactly.
