Where's the PCV Valve on 02 LS1s I've tried searching and still can't find an answer. What's the best one to get? Is this hard to replace? A picture or diagram would be great.

Look at the intake manifold just behind the throttle body on the passenger side. There's a 3/8" hose that exits and runs down the side of the manifold towards the back of the car. I believe the PCV valve is about 6~8 inches down the hose (at the front of the valve cover).
