I am trying to redo my vacuum lines. Here are some pics of my engine. '84 305in an '86.

Please look at each pic and give me any info you can.

A lot of the lines have screws at the ends as plugs. Carb had to be rebuilt after engine install so vacs are a mess.

Thanks for the help

 

THE CENTER ONE (T) SHOULD BE FOR YOUR PCV VALVE.

 

All of the diagrams I have show the PCV running into L into that T fitting and they also show that T runs straight to the canister control valve (which I can't find. I think I have the L line to the PCV correct. Here is the diagram I am working with....

 

That canister is pretty easy to find. Take a trip to your local junkyard & look under the hood of any 80's Chevy V8 powered car, all the bits you are missing are in there... try to find an '86, '87, or '88 Monte, Caprice, El Camino, Grand Prix, Camaro, or Firebird. These later car's pieces will work properly with your version of the CCC computer system. The system changed a little each year, so make sure the diagram you use is from 1986.

 

canister = orb of power.... that thread was awesome XD

 

I finally saw a pic of it. I will pick one up today. slowly but surely I am getting this figured out.

Anyone else with help on the pics. In particular in pic 2 the "what plugs into here" part?

 

That's a pretty thorough mess.

The check valve in the line going to the PCV valve - that's supposed to be in the vapor canister system. Get it out of the PCV line.

Your Pic 2 items: Carb goes to the vapor canister control valve (which isn't even there), the lower ones in the pic are the EFE TVS in the diagram that has been posted for you. The EFE is the "heat riser" valve between the passenger side exhaust manifold and exhaust pipe.
