Add me to Suaru owners who's cars have piston slap. Mine is a 2003-Outback Wagon, with about 43,000 miles. We live near Syracuse NY so this winter was cold and snowy. The noise just started this winter. BTW, we use an engine block heater (Subaru installed) and the engine still knocks in the winter when we drive off. The timing belt tensioner was changed and that didn't help.

I have a 2003 Outback/4cyl/auto with 42,000 miles. The piston slap noise started this winter and it's getting worse. Under warranty, the dealer replaced the timing belt tensioner and the nose remains. I now have an appointment with the zone rep coming up soon. And this car is a replacement for a 2002 that was returned as a lemon. I also have a 1995 Mazda 626 with 226,000 miles and that engine doesn't make a bit of noise. So Subaru has a big problem here. Back in the 60's, when I was in high school, only worn out engines had piston slap.
