What does PCV stand for Honda?
A typical Honda crankcase ventilation system uses engine vacuum to draw contaminants out of the crankcase and reintroduce it back into the intake manifold for recycling. It’s known as the positive crankcase ventilation system (PCV), but it isn’t the most effective thing in the world.
Why are all PCV valves made the same way?
Almost all PCV valves are made in the same way, two hosing connectors with a spring-loaded one-way valve inside of it. When the engine is at idle, you have a lot vacuum inside of the intake manifold, which helps the emissions to get sucked out from the crankcase efficiently at lower speeds.
How long does it take to replace a PCV valve?
Overall, if you have an older car, the PCV valves are often easy to replace and should only take around 10 minutes, while on newer cars, there could be a replacement time of over 3 hours if it’s located under the intake. Sometimes, you have to remove the intake to access the PCV valve; luckily, this is not that common.

Because the PCV valve is often mounted in hot places inside the engine bay and because they pass a lot of fuel/ oil inside the hose at all the time, this will cause the PCV valve or the hoses to crack up sooner or later.
Where exactly is location of PCV valve?
The PCV valve is often, but not always, placed at the valve cover; it may be located anywhere between the crankcase air outlet and the intake manifold. Carbon build-up in the intake manifold may occur when blow-by gases are allowed to permanently contaminate the intake air because of a failing PCV system.
