How to Take Out a PCV Valve

A PCV valve--sometimes erroneously referred to as a "PVC valve"--is a Positive Crankcase Ventilation valve, and is responsible for the continual expelling of gas from an engines crankcase. This is a one-way valve. If you do not change your oil at regular intervals, the valve can become plugged and fail, so you should perform regular oil changes. If the valve does fail, youll need to know how to remove it in order to replace it.

Instructions

1

Pull the hood release lever to open the hood of your vehicle.

2

Run your fingers along the inside of the hood to locate the hood release latch. Once you have located it, pull up on the latch to open your hood.

3

Locate the PCV valve, which will be on the crankcase. Look on the top of your engine or on the sides. It is a small rubber plug that is stuck directly into the engine. It looks almost like a rubber bottle stopper.

4

Pull off any hoses that are attached to the valve. There are two main designs of PCV valves. One is directly plugged into the crankcase, while the other is inline with two hoses. If your vehicle has an inline PCV valve, youll need to simply pull the hoses off the valve and then remove the valve itself. If the PCV valve is plugged directly into the crankcase, youll need to grab the end of the valve with your pliers and twist the valve. Youll need to give it a good pull, but it will come out.
