I have a 2004 Forester 2.5X, auto tranny, ~14,000 miles; I've had it for about 14 months since it was new, and I do not drive it hard.
It has a troubling noise: I can hear valve chatter, or tappet noise, or pinging, under moderate acceleration. At least, that's what I think it is. I can hear it more easily with the windows open. It's not terribly loud; in fact it's almost masked by the overall noise of the vehicle.
Do other people experience this?
