stock oil filler/breather cap

[85begalttype]

does the stock oil filler cap act as a breather if i plug up that hole that goes to the air intake tube?

If you are refering to the 84/85 hot air cars the the engine breathes thru the hose that goes to the intake tube from the oil fill tube. If you plug the holes your engine will not be able to breath unless you install another form of breather in the valve cover.
