I cannot speak to all C5s, but my pcv valve is on the drivers side, top, rear of the engine close to the firewall. It looks like an ordinary PCV valve (provided you know what a pcv valve looks like). I am also assuming that you have removed the rail cover on that side, otherwise it will be difficult to see.

Pcv Valve
Thanks for the comments.
Found my C5 '98 PCV valve on the PASSENGERS SIDE on top if the valve covers in the bulge in the large hose running front to back.
Was very clean. Took it out and cleaned it with brake cleaner.
Good for another 5 yrs.
Why does GM move this part around so much?
Thought it was inside a large HARD PLASTIC round cover at the very rear of the drivers side valve cover. When I originally tried to remove this cover it looked like it would BREAK. What the heck is hidden underthis cover?

LS6 Valley cover vents into intake. No PCV valve.
You can plug yours and get LS6 valley and be way ahead.
