PCV valve is an easy check, and they are cheap to just replace.

After that it's removing the intercooler and the downpipe (possibly headers) to track down where the oil is coming from. After that, it's compression and leak-down time to try and narrow down the search.

As others have said, and I agree, that is excessive even for break-in.

The Subaru dipstick is also pretty terrible, so you want to be very sure that when you're checking the oil, you do it EXACTLY the same way every time to try and reduce the variables that can cause inconsistent readings.

You want to set yourself up for repeatable and accurate feedback if this ends up getting messy with the dealer. You're likely in this for a couple of thousand miles more before anything would actually 'happen' with a repair, so document what you do and make sure you're staying in contact with the dealer just to let them know and further document your observations.
