It is knocking and noisy when it is cold. When warmed up it is ok. Why?

For the most part subaru engines are noisy by nature. Most likely, you are hearing a bit of valve lash that is a bit on the loose end of the spectrum and when the engine warms up it is where it should be. If that is the case then it is nothing to really worry about.
