Is PCV valve part of emission system?
Is PCV valve part of emission system?
Although the PCV valve is considered an emission control, they have been around long before emission controls came around in the mid to late 1960’s. The first PCV valves showed up in the late 1950’s / early 1960’s. To understand the PCV system, you first need to understand some basic engine principles.
Where does the PCV hose on the driver connect?
Engine vacuum diagrams please? The pcv hose on the driver side of the 5.7 liter engine connects from the valve cover to the intake manifold. There is another smaller vacuum line that comes from this connection at the intake manifold. Where does this vacuum line connect?
Is there a vacuum hose for a PCV valve?
Also, keep in mind that some new models, don’t have a PCV valve at all. Instead, you’ll find a simple vacuum hose going from the valve cover to an air inlet duct.

How does PCV work in a crank case?
The pressure in the crank case is now going to be about equal to that in the intake manifold, so not much of anything will flow through the PCV hose. The blow-by gasses will have to continue on through the valve cover where there is even more built-in oil separation labyrinth.
Can a Nissan engine be used as a PCV?
While this article will use a Nissan SR20 engine as a reference, the information found here can be applied to all motors. If you’re reading this you’ve likely asked a question about crank case ventilation, catch can placement, correct PCV hose routing, or similar. Grab yourself a beverage of your choice, sit back and relax.
