Yes on the valve cover line and there are those who sell them even though one can make one from the auto parts store work:

pcv valves usually dont go bad,in design they are a oneway valve that lets pressure created by crank rotation pushing pistons up for compression,when too much pressure is created beneath and behind the pistons in the crankcase it creates positive or excess pressure. While some pressure in the crankcase is needed, too much is counter productive,hence the pcv its for relief.a relief vavle essentially!usually attached to a vacuum line  hose,and plugged into the valve cover they can be taken out and sprayed with carb cleaner

and blown out with compressed air.
