AMC 304 with 360 Intake PCV Problem!

On my 304 i am running a two barrel 360 intake, behind the carb it does not have a spot for a pcv valve, it has a tube screwed into the intake where the pcv would normally be. I am not sure how to add in a pcv valve and i know that it needs one because i have oil vapor coming from the oil fill tube and also i seem to be developing leaks from the crankcase pressure. My valve covers do not have a spot for a pcv valve either. Also does the pcv need manifold vacuum to work?

Which intake do you have?

Pics would help.

(I'm almost 100% certain that the OEM 2-bbl 304 and 360 intake manifolds are the same, so specifying 360 doesn't change anything). The PCV valve on the late model engines is an inline valve. Look at this thread:

This is the valve you'll use:

I run a 90° elbow in the intake and then strait to the carb.

That's an aftermarket intake, which uses a different PCV valve.

Its an aftermarket intake, but still would use the stock PCV valve. I chose to use a 90° PCV valve that I got at the auto parts store (tell the counter monkey to go pound sand and find it yourself.)

Just using this pic mainly to show where the PCV grommet/Valve would be located in the intake.

It uses a stock PCV valve for an earlier intake; his problem is that he's got a late model OEM intake, so the 90° PCV valve doesn't work--he's just got a tube threaded into a hole. You have a different PCV valve than what OP needs.

All he needs is the correct grommet for the hole and the PCV valve will fit into it.
