Apparently there is a technical service bulletin on this. TSB 10-06-01-008M GM redesigned the valve cover, part number 12642655. With 200,000 miles I don't imagine I can get mine replaced by the dealership although oil consumption has been a problem since it was new. Found one on ebay for 49.95.
White smoke at start up after a 2 hour trip.

I can't recall the part number but yes, it was dorman brand. I bought it on rock auto for like $80 or something. GM does have a revised part number but I couldn't really verify which one was correct for my year. They mover the PCV in the later ones and I wanted to make sure I bought the correct one, so dorman it was. I figured the other one last 100k miles, if it clogs up again in another 100k, I'll buy another one. The only thing I did was water sand the dorman logo and "Wade in China" off of it and polish before I put it on. Didn't want that staring me in the face every time I open the hood, lol

I have a 2007 Yukon XL 5.3L with Oil consumption also. When idling what is you oil pressure at? Have you changed your oil pressure switch? I have also read that can lead to AFM lifter failure as it starves the lifters for oil when it starts to get clogged up. They recommend just taking out the filter thats there also
