Lately my VX has started burning oil a whole lot faster than it used to.. probably about 1 quart every 1000 miles now. making me kinda nervous..

at a car show the other day I saw a grand prix with a breather filter on his oil filler. I know some VX owners have done this on their PCV. any harm in giving them both a try? I know some oil pressure is a good thing, will the filter stop pressure buildup? any thoughts would be appreciated
