VR17 Posted March 22, 2003 Share Posted March 22, 2003 it should be located around your valve cover to your intake airbox or somewhere by your intake manifold. Here is a demo for your noobs about a PCV valve and its funtions and why you have one on your car.. and reasons why you dont connect it back on(most people just put a filter or air cleaner filter). When an engine is running, a tiny amount of the exploded gas-air mixture forces its way past the piston rings in a condition known as blow-by. These fumes would build up pressure in the crankcase and cause trouble if they were not allowed to escape. PCV valve prevented gasses from building up in the engine but it also allowed the oily fumes to escape into the atmosphere. most cars have many types of pollution control devices to protect the quality of our air. The system used to control crankcase fumes is called Positive Crankcase Ventilation or PCV. In this system, the PCV tube leading from the crankcase is not vented to the ground but is routed to the intake manifold where the oily fumes are sucked into the engine along with the gas-air mixture and burned.
