    Where is the pcv valve on my Yukon? I did notice Advance Auto doesn't carry one, makes me think it doesn't have one.

    drivers side valve cover rear (close to firewall), the tube exit's there and goes up into the top front center of intake, I believe the valve is integral to either the valve cover or the tube it's self. It's just a ball bearing inside if it is clogged for some reason you can just clean it as long as the tube isn't cracked or broken. There is a updated valve cover that is supposed to help prevent oil consumption (oil gets sucked into the intake) some of the members here have a installed a "catch can" to trap the oil fumes and help prevent any oil from entering the intake.

    No more moving parts. Just restrictions as part of the design.

    I did see the two PCV tubes, so I guess that would be the dirty side with the valve in it? I have no oil consumption, but I do have a drip of oil staring to show up on the transmission. I figured if it has a clogged PCV valve or something that my cure it instead of having to change a rear main down the road.

    Looks like I was wrong fellas, they went to a different design for 2009 and on. Thanks Wes and Rene.
