What connects to the PCV valve?

The major component in the (PCV) system is the PCV valve. It consists of a simple spring-loaded valve with a sliding pintle inside. A hose connects the top of the (PCV) valve to a vacuum port on the throttle body; carburetor or intake manifold. Allowing the vapors to be siphoned directly into the engine.

What happens if you disconnect PCV hose?

PCV system routes oil vapours back to the intake to prevent blowing them to the atmosphere. If you disconnect it you’ll have a cleaner air available to the combustion process, and so better performance.

Is the vent from the PCV valve back into the air?

There is something called a pcv/ccv which has a tiny hole and acts as a valve. Usually further away from the front of the vehicle. Then, what I think OP is asking about, is basically a vent that goes into your air filter which is often misidentified as a pvc valve and ordered incorrectly because they look identical at a glance.

Why is oil in my air intake tube?

I found oil in my air intake tube from the the throttle body to the MAF sensor. Through some research the reason is that the engine has 2 pcv breather valves that will cause the issue due to the rear one being clogged up. Thanks! Loading…

How to drill a hole in a PCV valve?

Drill the pcv valve, remove the spring and other valve mechanism inside so it will be just an air passage, completely hole, no valve, and connect hose to the catch can. Dont forget to plug the vacuum from the intake.

How is oil returned to the PCV valve?

It is returned through the intake because the vacuum presure of the intake matches the crank pressure that needs to be released. You could. Run a mechanical or an electric vacuum pump to release the crank pressure, they say a mechanical pump is better, run of a belt it pumps more at high rpms and less at lower rpms.

Do you put PCV into the CARB or into the intake manifold?

Use a carb spacer with the port in it. The spacer will also add some vacum & reduce heat to the carb. I would put it in the air cleaner, many HIgh performance cars came that way from the factory and would dissipate any fumes into the incoming air better.
