I am still breaking my motor in, I don't even have 200 miles on it. I have never owned a subaru before, so I am new as to their sounds. By not being finished with the stereo yet, I hear every little sound out of the car. I have noticed that above 3000 rpm's when the engine is under a little boost at maybe half throttle, a consistent clicking is heard. I don't know if its a noisy valvetrain or an exhaust leak or what. If its normal, I can deal with it--just wanted to know if everybody else's does it too. It doesn't do it when you're light on the gas, just around medium throttle. I am being very careful breaking the motor in, so I don't know if it goes away when you lay into it.
