PLEASE change out the PCV (and clean the PTC nipple at back by the turbo) as soon as possible and you may be able to save it. My smell had been getting really horrible, and I'm fairly sure my car blew out the rear main seal while driving to NC today. It's bleeding oil all over the bottom of the car and driveway like a stuck pig, and it's dark so I can't really pinpoint where it's coming from.
I did my whole PCV system about 2 weeks ago, after putting it off for a long time, but apparently it was too little too late. I smelled burning oil even with the air off and windows down every time I got on the gas to go up a hill today.
There's a great write-up that I followed here: http://www.lakesidedp.com/uploadpics/pcv/index.html
Replacing the rear seal is not for the faint of heart - I'm not even going to attempt it myself, so it's best if you can still save it!

Since you replaced the gasket, that opportunity has been sealed off from it and it's blowing out the seals instead. At least that's what I'm thinking.
I agree, give the engine a good cleaning-up and see where oil re-appears. It's kind of all over everything at the moment. Take off the turbo heat shield at the back of the engine and have a look around there. In the meantime, don't romp on the throttle a whole lot.
What kind of oil do you use?

I'll add some pictures of ours.
Good luck, hope this helps.

And it's Justin btw

Yes, the oil return line is the same thing. They are known to leak quite often.
Welcome to the forum, I wish you enjoy being here.
Oil leak from the turbo return line is a common problem and is a cheap & easy fix. You only need to replace the seal ring & gasket. The following vendorhas all you need:
If you have floor jack + jackstands + common sense for safety, you can do these by yourself, otherwise you may want to take it to a shop.
Good luck to you,
