    Anybody by any chance have a picture of a Vortec/EGR intake - "goofy pipe" setup - how's that return pipe routed, and does it need to have a heat shield?

    I want to (at least for now) try to keep EGR and EFE on my '85 engine makeover (if I ever get those vortec heads delivered, that is) and set it up to work with TES headers with AIR (all those acronyms alone seem good enough reason to start to looking around for a pre-emissions truck). I'm considering to use the AIR connector on the left header to draw exhaust gas for the EGR and route AIR down to the oxygen sensor port on the header (don't have the sensor, it's carbed).

    I'm afraid I see a small pipe bender in my very near future...

    thanks for any pic or advice, michael

    the EGR is very basic; the exhaust doesn't come from the intake to the EGR valve, you have to take it from the header, and use that pipe to plumb it into the intake. pretty basic.

    on my 89 I'm in WY so I just put a plug in it.

    If you ordered your headers for vortec heads they should be EGR ready. The factory EGR pipe is fitted on either end and has some sort of insulation stuff built on to it. Your local dealer should have one on hand.-Jim

    I do not remember any place to connect the EGR into that would go into the head its self. (maybe I'm wrong, but if I were then you'd see exhaust coming out the side of the head wouldn't you, or a plug in its place.

    It would be the intake that accomodates the EGR, and it doesn't. thus the pipe and the fittings required.

    The EGR goes directly from the exhaust manifold on the drivers side to the drivers side front of the intake. No provisions for EGR in the cyl heads themselves.-Jim

    Jim,

    forgive me it has been a long day; for some reason when I saw headers I thought you said heads (which didn't make any sense to me... LOL)

    Thanks for the advice guys. My headers are regular Edelbrock TES, so no EGR provision, that's where I'll have to wing it and maybe use the AIR fitting. Jim, haven't found a dealer parts man here - from my San Diego days, I fondly remember El Cajon, the capital of 4x4 shops. I'm still wating for the vortec heads (ordered Nov 2!!!), so I don't have a good idea what exactly needs to be done. Solo, I have the Q-Jet vortec intake with the exhaust gas in-port on the front driver's side. I was just wondering whether anybody else has a pic for the setup so I'll have a better idea what I'm in for.
