So I took my blazer to get the Virginia safety inspection renewed at the same place I have for 5 years, and they failed it for not having an egr valve. I have a non egr edelbrock performer intake and carb. So I'm going to get a egr preformer intake and get the egr valve. But I saw that edelbrock carbs are listed as non egr, and the guy I talked to at edelbrock said that the only carb that would work would be the stock one. Does anybody know why I would have to have the stock carb, would the egr work with my edelbrock carb. Any help about this would be great, I really need to get the blazer back on the road before winter. I also don't know how the egr hooks up, don't know what the egr solenoid looks like.

 

it looks like a flying saucer, its located on the back left side of the engine if you are looking at the engine from the front

heres the picture of the egr valve



it basically just has one vacuum line going to that goes to the carb. i think if you have 2 ports on your carb you can just run a line to one of them, the people there probably arent going to know the difference if its hooked up properly or not.

heres one on a old truck (just left and above the carb) i used to own. see it just runs a line directly to the carb, i believe to a vacuum source that only works under throttle but not sure. i havent ran a egr valve in a long time

 

Thanks man, yeah I see what you mean. I think the port on the left of my carb is only vacuumed under throttle, its the vacuum advance one that the distributor runs to, I could just T it off of that, and yeah I doubt he will know if its hooked up right either, he was in a really bad mood that day normally he would have passed the inspection, has for 5 years anyway. I just did not know how that stuff worked on this truck, cause really it was kinda butchered when I got it, stuff taken off, wiring and electric plugs just hanging loose with nothing to connect them to, just crazy still don't know what most of them used to go to. I did not even know the truck had an ecm till I just saw it in the Haynes manual. Thanks again.

 

yeah it has some kinda goofy ecm that controls the carb and i think the distributor. i dont really know that much about them but have seen them in vehicles i have owned.
