I've had 3 Subies, this one was an 08 with 150k that had regular oil changes. It dropped a valve guide. I did the job myself and it still cost 2 grand. Suck part is the car lasted 6 months after the repair and had another unrelated engine failure. Should've cut my losses and split after the first failure but I bought it new and got 150,000 trouble fee miles so I'm not too disappointed. Ended up selling it to the dealership and walking away.
