    Could be coming from the PCV spacer under the carb. If the PCV is sucking a lot of oil, that'll end up possibly coming out where you describe.

    The PCV is not part of the pollution control. It is needed to let the engine breath. Without the PCV you will push oil at the weakest link. Hook the PCV back up and it will stop leaking.

    a long shot, but possible is the intake manifold has a crack and the oil in the lifter valley is able to get through the crack. my first thought is the pcv valve hose is leaking oil at the base of the carb but am unsure if there is still a pcv valve on the car still. you should have a pcv valve it only helps and doesnt hurt.

    Make sure the PVC valve or valve cover vents aren't plugged up...If so, crankcase pressure could be building up and it'll find any way out it can

    Re-adjust your carburetor and timimg with the PCV hooked up.

    is the hose on the pcv valve soft and plyable or dried out and hard?
