If it is just piston slap...almost every 2.5 Subaru engine I have heard has had some. My family has had 3: a 2.5 DOHC, a 2.5 SOHC, and a 2.5 turbo SOHC. The turbo is the only one that doesn't have some slap.
That being said, does it quiet down when the engine comes up to operating temp? Our 2003 has a decent amount of piston slap/tick at start up and quiets down to very light noise after the engine warms up.
