The 6.0 and 6.2's don't really need them, but the 4.8 and 5.3's do.

There's an upgraded valve cover that limits the oil blow by. It's got nothing to do with engine size other than the newer engines having the redesigned cover. My catch can gets a good amount blow by oil in my 6.0.

After looking at this if you have a 6.0 with the PCV built into the valve cover then it's the upgraded valve cover? My 04 Escalade has the 6.0 and doesn't have a removable PCV valve it's built in as pictured
