right, the pictured is H6, which is virtually indestructible Subaru engine, so whatever we see on the picture is likely a result of abuse
on 2.5 EJ head-gasket topic, seriously, after many-many years Subaru did not care to do a thing ?!?
Yes, engines in 2007+ were supposedly getting some “updated gaskets” and we were told “now it is OK”, then reports of similar failures started to popup.
I used to have 2007 Outback with normally aspirated 2.5 - it was a great car, but I sold it just before it hit 100K mark as I was afraid to hit the issue
Repair shops specializing in Subaru repairs were reporting that 2.5 with turbo was not prone to failures, as they used some special multi-layer head gasket design, which fitted normally aspirated engine just fine, moreover, they were reporting that using that [more expensive] gasket in normally aspirated engines resulted in vehicle not getting back with this problem ever. Taking it with a grain of salt, but I assume it worked much better in any case.
Now, as a formed owner of 5 Subarus and still liking the brand, I would rather see them spending $20 more per car with a better gasket rather than pouring more and more ads into any media they can reach. Not a Subaru way unfortunately 
To be fair, new FB engine design will definitely plug a head-gasket issue for good, but now they have an excessive oil burn issue plaguing it
I was hoping to get back to Subie after they fix FB childhood issues, but it looks like they are not out of the woods yet.
