I would certainly check the PCV valve as a start.

Just remove it and give it a shake. If it rattles, it is likely ok. They are also cheap to replace, so you can always swap it out as preventative and see if that solves the issue.

While I agree with dmsfun that a stuck PCV valve could eventually cause motor damage, I don't think the amount of oil you are burning through necessarily indicates your seals are blown. In my experience, when a PCV valve is stuck wide open like that you'll also have issues at idle (which you do not report).

I think a couple of quarts in a few thousand miles could be just the valve staying open itself.
