I'm not sure about your 1972, but my '81 vacuum layout has the PCV line T'd to the charcoal canister.

Intermediate CJs have the PCV hose tied into the carb with a 3/8" hose. Mine ties into the back of my Holley carb and did on my Motorcraft carb as well. I have a 90 deg elbow on top of the PCV (one that I found would work from Autozone) and the 3/8" hose inserts into the elbow nicely.

Thanks everyone. I'll have to find my setup. I have an edelbrock manifold with a Carter AFB carb.

I took my grommet to the parts store and asked for a 90 PCV valve. I think mine fits a Chevy, cant remember. But it makes for a very clean installation.


Beat it to fit, paint it to match!

That is pretty clean. I'll have to look at the back of my carb. I don't remember it having a hose port back there.

Greek,

I think the straight PCV will work better with your setup.

As you can see, 82 has an Offy manifold. His PCV grommet sits higher than yours in relationship to the carb, so a 90* valve works well for his, not so much for yours.

I agree with this. I have a straight PCV and a short radius bend on top of it that works well. I'll try to remember to snap a pic this evening.

I see what you guys are saying. What's confusing me though is my carb has, what i think is the pcv port on the front and i have a hose connecting it to a pcv valve on the forward section of the manifold. I'll get a pic of the hose going to the pcv valve on my engine later but here's a pic of the carb i have. http://www.camaros.net/classifieds/data/5/IMG_3254.JPG

My PCV port on the manifold is not any higher than a stock manifold. With a 90 valve, it just about sits flat with the port at the base of the carb.

Beat it to fit, paint it to match!

I got pictures of my setup and the PO actually had a bolt capping the pcv port on the carb. I'm gonna order the pcv valve and when it comes in I'll get the port insert for the carb to make sure the hose fitting is the same size.

Steve, I forgot to ask you, will the grommet from Summit that you posted fit on my edelbrock manifold or do they differ in diameter depending on the manifold type?
