Wete does the pcv tubing go on1999 chevy lumina
The EGR valve on a 2000 Chevrolet Lumina is located inside the intake manifold. A replacement valve can be purchased at any auto parts store.
Under the air cleaner box
The EGR valve is located in the center of the intake, at the front of the engine, between the alternator and the A/C compressor. I've added a picture of the location under "Links". It is titled "Picture of EGR valve location, on 1996 - 2001 4.3L (262c.i.) Vortec V6 engines"

On my retrofitted to R134-A the fill valve is underneath the airbox. You have to take it out to get to it.
on the right of your PC valve Where is the PC valve?
There is no such thing, the right name is EGR valve which stands for Engine Gas Resurculation (bad speller) valve.
in the valve cover
It's under the plenum in the back of the engine.
I have a service manual picture doesnt really explain anything pcv is not really visible. The 2.2 1998 and up had a non-serviceable PCV system built into the valve cover.
Yes...it is located on the back valve cover on the driver side. It's hidden well and a little difficult to get to.
