yeah mike thats exactly what haynes says as well
thanks for the pic and nice Truck by the way
I don't have that rubber gromet on the left valve cover in the pic
Mine has a steel nipple in that spot, that is pressed in and a plastic line
with a rubber elbow that fits over it that of course goes back into the top of the intake.
but no PCV valve.I'm gonna get a hold of the dealer parts guy
because I can't find the EGR valve either
I found a diagram of my motor on this site but it shows nothing but PCV tubes

I see you have a......2005" Silverado with a 5.3 liter......in 2004"and up...the PVC Valve is made in the Valve Cover it is Not removable....this is something I found out about from a previous thread here on the site and from a friend who is a mechanic.
On the EGR Valve.....Starting In 2002" the factory removed them.....and this I had confirmed with my local Chevy Dealer.
