Reliability, common problems and owner reviews for the Subaru Legacy / Outback 3.6R (EZ36 flat-six). Check this before you buy used.
The EZ36 flat-six is the unsung hero of the range — smooth, torquey and genuinely robust, with no head-gasket vice and chain (not belt) drive. The catch is running cost: it's thirsty, AWD running gear and the auto want servicing, and it's a niche engine for parts. Mechanically it's the engine to have if you can stomach the fuel bills; an honest high-mileage example is a safe bet.
