this is all things i've heard secondhand, but i've been told that they really don't do too much and are basicly useless on an otherwise un-modified engine. The 3400 is only 170 hp and adding an oil breather isn't really gonna make it into something special. if you are insisting on doing it, do it on the oil cap because thats no vaccume. the other tubes are vaccumes and it will make them ineffective.
