Yes, there should be vacuum and it is normal but the hose should not be plugged. It should run to the air cleaner, inside the filter or to it's own filter. Otherwise the PCV system will not work properly.

On the stock air cleaner housing there is a plastic nipple that plugs into the air cleaner housing and connects to it's own special filter in side the housing. That nipple is what I used to do a PCV for my 428CJ with a 406 3X2 setup with custom ram air. Drilled hole in the base of the ram air container that fit on the carbs inside the air filter element and installed the nipple and connected the inlet hose to that.

The oil out the dipstick is caused by not enough air flowing into the crankcase to allow the PCV system to pull the fumes and such into the intake system. Once you have air flow thru the crankcase the oil out the dipstick will stop.
