Looking for stock PCV setup

So I just got some stock style valve covers along with a stock air cleaner housing, and I am now in search of the PCV that goes on the passenger side valve cover going into the extension between carb and air cleaner. Anybody repop these?

Re: Looking for stock PCV setup

While the physical arrangement can vary for different engines, the PCV Valve should always be connected to the vacuum source. In other words, between the vacuum source and the crankcase.
If the PCV valve is mounted in the valve cover, a hose connects it to the intake manifold or most likely a large vacuum port on the base of the carb.

Fresh, clean air flows from the Air Cleaner, into a valve cover, through the crankcase, out the other valve cover, through the PCV Valve and into the intake manifold to be burned.

A valve cover breather can be used on the fresh air side of the system, but those breathers are generally cleaned every 20 years. Taking the fresh air from the air cleaner, benefits from the air filter being replaced on a more frequent basis.

PCV valves are made in many configurations. You just need to make sure air can flow through yours in the proper direction.

I think he is looking for the ring between the carb and air cleaner that provides the fresh air intake for the PCV system.

I have one i plan not to use at a later date, but don't know when. It's on my truck right now.

Re: Looking for stock PCV setup

If I read the OP's post correctly, he's looking for what GM referred to as the flame arrestor and/or the rubber hose from the arrestor to the spacer between the air cleaner and carb. If so, I don't believe that's reproduced. Your best bet is a salvage yard or the parts board.

Re: Looking for stock PCV setup

I went through setting up mine last year. Here is a thread about it, with part numbers for the grommets and PCV valve that you might need once you get the flame arrester. I recommend ordering the grommets and PCV valve at a Chevy dealer.
