The oil tank and factory oil seperator on the later cars is vented into the air cleaner housing after the filter element on our cars origonally so taking off the oil tank cap shouldn't make much difference in CO emissions or AFR's unless the air filter is really dirty and clogged up.

Mine hasn't been stock in that area for a while now so I'm going on semi foggy memory of that system.. so I may be forgetting something. . .
