Unavoidably removing egr

I'm yanking all vacuum lines except vacuum advance. Do i have the green light from you gurus? What about this picture I've attached focusing on the five hole device sticking out of manifold

I hope you are not planning for a CA smog cert.


As for the CTO valve, it controls the egr and the charcoal canister purge; there is really no benefit to removing either of those. Here's a stripped down vacuum diagram.

here is all the vacuum lines on mine but jbolty is right, you need everything for smog. i removed the cto, the egr, the purge cannister, everything but the line for the distributor, hte line for the four wheel drive, and the cruise control vacuum.
