need baffles ?

Some of the parts stores back in Abilene used to carry baffled PCV grommets...they worked OK-better than having none at all, but still ingested some oil. Another option, aside from installing baffles as mentioned above (arguably the best option) is to run a pcv to a breather can mounted on the firewall or fender, then to your carb. It clutters up the bay a little, but almost completely removes oil consumption through the PCV

Something like this:
