It's been doing this for a while, mostly after being warmed up. I use 5w30, and never even take her to redline. Anybody know if this is normal? I don't recall my old Legacy ever making this noise, but it was a 90 model.
I had the same concerns but realized that it was just because I had put a Borla header on... The shrouding of the stock exhaust manifold muffles the normal "clicking" of the valvetrain. The Borla (or any) header has thinner guage steel and no shroud, therefore emitting more noise. It immediately became apparent when I compared my car next to a stock TS.

This, of course, is if you have a header.
