emission routing

(1/1)

mudfrog:
Have 86 Blazer full size 4x4 with 350 4bbl. Looking for anyone who has diagrams/photos of emission routing. I have all lines from charcoal canister fiured out. Having major difficulty with vacuum lines on passenger side of vehicle (EGR, TVS, EFE) I believe I am missing some vacuum check valves but have no idea where they go. Have already been thru the standard Chilton and Haynes manuals for tucks and blazers.  

Unixluv:
Here is the diagram for a 86 with 305, air conditioning and automatic trans.  If you need something different, try www.alldatadiy.com/

I love the diagram it is very helpful. If i plug all the holes can i remove all that stuff. We dont have testing up here in North Dakota and i think i am missing some vaccum lines anyways so i think it will run much better with it all removed.
