You would need to install a correctly functioning PCV system in its' place.I recommend visiting the Y-Block Forum on FTE for advice on how to properly install one.
That leak,while annoying and frowned upon in todays' more environmentally-conscious world,is normal - sort of.The intent was to vent crankcase fumes,while going down the road at relatively higher speeds.The reality,though, is different than intended. "Marking your territory" is part of the Y-Block experience.Embrace it.

As the engine runs it get vapors in the crank case that if not vented in some way can be corrosive to the internals. The vent tube is designed that when you drive the air blowing over the end of the tube creates a vacuum on the crankcase. It pulls fresh air in through the oil fill cap and "exhausts" the vapors out the tube. When you shut down the engine the vapors cool, then condense and drip. If you have a worn engine with lots of blow by, this get worse.
A PCV valve used the engine vacuum to suck on the crankcase, the oil fill cover is still the inlet and the vapors get burnt and exhausted out the tailpipe. No more drips. The system is fairly simple but you need a good vacuum source.
I replaced mine with a PCV valve. I removed the tube assembly, cut the tube off, made a rubber grommet that would accept a PCV valve and I had a good vacuum source from my new Edlebrock carb. I also replaced the oil fill cap with a new one with a nice clean filter. Works fine, I will try to take a few pics tonight after work for you.
At one time there was an aftermarket conversion kit, I have seen them on eBay, but it is easy either way.
thanks for the photos. I have a vented oil filler cap already. so it looks like you put a pcv valve inline from the old attachment point on the block with a vacuum hose attached going to the carb, is that correct?
Yep, that is it. Where I removed the vent tube from the part that attaches to the valley pan, I put a rubber plug with a hole in it that the pcv valve sticks into. Then I blolted it back on the valley pan.
