Denstoj Rocker Retainer Kit for FA and FB Subaru/Toyota Engines EJ Shortblocks 2015 Subaru WRX Premium 2We have discovered that the FA & FB engines have a flaw in the valve rocker design. The rocker arm can separate from the valve assembly after a valve sticks or bounces. Once this occurs the separated rocker arm becomes a projectile inside the engine. As soon as the rocker finds a camshaft lobe there is a seriously high chance (note, almost certain) that it will be blown through the engine. So we created a fix by retaining the rocker arms with a clip.
