Picture - The SOHC 2.5 is what Subaru should have stuck in the Legacy from the beginning. The normal technique to remove the heads is to pull the whole motor. But I figured I had more room to work with in the Legacy than the Impreza and Forester that the motor is found in, so I gave it a shot. Turns out, there is exactly the right amount of room to get the head bolts out - it makes me wonder what the bigger DOHC 2.5 had to offer that led Subaru to putting in that motor straight from the factory. The removal was surprisingly simple - unbolt the intake manifold, exhaust manifold, valve cover, and then it's just 6 head bolts from there.

Picture - I haven't looked at an EJ257 piston in a while but I don't think there is any damage to the piston - seems what we're looking at are the standard valve reliefs cut in.
