Hey guys,

Was going to swap out my Airfilter/Valve Covers, Well, was wondering what lines I can remove, there is all these air lines ect going to the airfilter housing, the valve covers ect ect. Is there anything I dont need and anything I have to have?

I'm thinking this would all depend on your state emission laws.

This is my personal opinion but if your whole stock setup is complete and works i wouldn't mess with it unless emissions isn't a concern.

My truck will be exempt in 2011 so im not worried about emissions, My valve covers leak really really bad right now to the point where I wont drive it. I just figured since im replacing alot of stuff I would just swap the valve covers out with some fabricated aluminum ones as well as a spun aluminum air cleaner..

Make sure you don't have to take the sniff test next year. even if it is exempt next year, if you didn't get it done this year, you could still have to take the test.

i agree with 79GMC15, but if your truck is gonna be exempt from emmisions then i'd take it all off lol sell it to someone in california who needs it

Don't get any stamped cheap valve covers. Go with some nice cast aluminum ones from proform. They will seal much better then the stamped junk.

Also keep the PCV setup so that it will pull out some of the crankcase pressure.

The charcoal canister for the fuel tank is probably a good idea to keep as well so that you evec all the fuel fumes/vapors.

Ha.. and I'm sure they'll be plenty of takers.... post it up on E-Bay!
They're rediculous here about the smog reg's

It's really hard to find somebody who's even willing to tinker with these q-jets anymore... to get them to pass (or even knows how to)

I know you are going to do what you want to do, but that is a very clean stock setup, I wouldn't change anything but the gaskets.
