I just got my WRX back from the dealer a little less than a month ago. It had a spun bearing so everything was replaced. They just told me to follow the break in procedure in the manual (under 4k rpms for 1000 miles with no boost) Typically how long should you wait to change your oil after work like this? I'm just really paranoid that something is going to happen to my car again. My car has about 600 miles on it since i got it back from the dealer.
