Visual learner with a California Camaro owner trying to pass smog. I have most of the components (EGR valve, Map sensor, canister, AIR system, diverter valve) just need help figuring out how to run them. I have a diagram but some pics would greatly help.

1st off, pcv valve goes on the dr side valve cover to where you have the brake booster hose.
Brake booster hose goes to driver side back of plenum.
a open 90deg fitting goes into pass valve cover the top pass port of the t-body.
2nd port down in t-body goes to the charcoal canister

 

Here is my 92 Z28. If you need more pics, let me know.

 

You need a Factory Shop Manual for your specific 3rd gen. They can frequently be found for sale on ebay, craigslist, FB marketplace, etc. Don't rely on Haynes, Chilton, or any other non-Helms publication; these often contain incorrect information.

 

Appreciate it, I figured it was wrong but knew there were a few different configurations. I’ll post pics once I get it all back together.

 

So nice and and neat bro, I have to get mine there. Thanks for all the help. If you could possibly send some detailed pictures of how the air pump and diverter valve hoses are lined. My car is missing the smog pump and AC compressor. So I just really need a general idea of how the hoses were ran in that area.

I borrowed this picture but I also have this sitting aside as well. Thanks again

 

but I these hoses here are the ones I’m completely lost on. Thank you

 

It looks like your air pump
or diverter valve is gone

 

I just recently bought the diverter valve and the plastic ufo ship looking thing lol it’s sitting aside, I am missing the AC compressor and air smog pump. Going to grab those soon

 

What year? '85 to '92 TPI are set-up differently. It's all the same idea but different set-up.

Edited: I see a MAP sensor, so I assume '90 to '92, right?

Edited: who ever butchered this car most likely tempered with the tune. Might want to make sure AIRS, EGR and CPP were not deactivated as well as other mods that would render the car non compliant on the sniff test, like 160Deg.F thermostat (if you have such thing in CA).

 

These should help for seeing how the AIR system is set up.

 

“transamgta350” , will those headers with one AIR tube replaced with an EGR supply pass SMOG ? , In states not as stringent as Cali?

anyone tried it?

 

Not sure if it will pass California SMOG or other states with visual emissions inspections with the external EGR tube. I guess it just depends on how hard they look and if they know what they’re looking for. If that’s a concern, best to use internal EGR heads like the stock F-Body setup. I’m in Connecticut and there are no emissions inspections after 25 years, so a non-issue here. I just wanted to keep the emissions equipment in place and functioning.

 

Where in CA?
