major problems BVSV / vacuum / wiring...
hey every one i need a little help here... i need to know where the wires that are attached to the green connectors all go to (i dont have any couplings to the green connectors) i think the red one goes to the alternator im not sure... but i have no idea where the 2 go to that are attached to the solenoid valve. also i have no clue what the little canister attached to the carburetor is either or where the green wire, black wire and the vacuum lines go on it, and i have no clue where the vacuum line i have circled goes that is coming off the small pipe warped around the carburator because its not on any of the diagrams i have... (first pic)
Also in the second i don't know what was in place of the 3 bolts i have circled was it BVSV valves? and is the thing i circled next to the carburetor a BVSV valve? again im not sure. (second pic)
(info on engine) this engine was EFI and has been converted to a carburetor(don't ask why i don't know) the manifold is not stock and the carburetor is on a quarter inch riser to clear the cam mechanism from the manifold.

I am in California, which requires all smog equipment to be present as well as operate properly. My registration is due and had a smog, it failed miserably... The tech told me the BVSV is faulty, and there is no vacuum going to the EGR. Is there anything else that I should look at while I'm elbow deep? And are there any home-made remedies for cleaning or reusing the EGR? I know the BVSV needs replaced, the plastic ends which the vacuum lines plug in are broke off...

You can pull the EGR off and give it a good cleaning, make sure all of the internal passages are clean and check the daiphragm is good by putting a hose on the vacuum fitting and sucking on it to dreate a vacuum, you should be able to see the diaphragm move if its good. Also check the vacuum modulator (i think thats what its called), round plastic thing with 2-3 vacuum hoses going to it, its what regulates the vacuum that goes to the EGR among other things, and check all of your vacuum lines to make sure there all there and hooked up properly.
