I lived with cold engine piston slap on my last Subie for over 200K with no issues. However, the sounds I've been hearing out of this boxer (my fourth boxer BTW), are not piston slap and only happens when the engine is warmed up. But there are only 9K on the car, and it still performs well, and the noise is not consistently there (except for the crickets). So I'm not freaking out just yet. Time will tell, but this engine does make some odd and unnerving sounds.
