It will decrease the life of your oil, as you wont have anything sucking out the bad stuff from your engine.

You really need to get a vacuum source setup to pull from the covers.

Bascially same concept as your, with blocking everything off and running 2 hoses to a catch can, but then running another hose from the catch can to a vacuum source, preturbo, like the intake filter, or the side of the turbo inlet.

so running the 2 -12 lines. one from each valve cover, to a catch can. then run a third line from the turbo intake to the catch can... would it matter that the line would be really long as its a rear mount...

Just cap (vacuum) it and run the vented can; I do and there's nothing wrong with my oil.

Have you sent your oil out to get tested? Or you just looking at it, and saying "Looks good".
