I have the 2007 Reno 2.0L 4. It's the one with the PCV valve in the valve cover. I'm having trouble finding the seal that is in the valve cover and snaps around a down tube. I got all the gaskets for the valve cover but can't find this seal. It is a big around as a fifty cent piece. Was told at the dealer that I would have to buy the whole valve cover. But it is a removable seal. Hope I explained it right. thanks!
