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.
