PCV valve replacement horror story

Check your PCV valve and the hose that attaches to it. This PCV valvle is usually located on top of your valve cover and usually have a 90 bend in it. I would replace the valve and check the hose for any cracks. The PCV valve should look like this.

You just told us

PCV Hose

Take it to an auto parts store
or dealer if not at parts store.

PCV Valve is in one of the valve covers with a hose connected to it. Pull it straight out of the valve cover and remove it from the hose. Shake it to see if the valve moves back and forth. If not, replace.

You have the wrong type hose on the pcv valvle. It isn't vacuum hose.

PCV is an acronym for positive crankcase ventilation.
The PCV Valve is a very common replacement item on many engines today. It's called the PCV valve for short but it stands for Positive Crankcase Ventilation. When your engine spins it many times collects pressure in the crankcase area, and it has to escape to relieve pressure on the motors bearings and seals. The PCV valve and PCV system is typically located near the intake manifold, and many times comes right off of the valve cover. It is very simple to replace the PCV valve, and you can do so by simply unscrewing it, and screwing in the new valve. We recommend using a little bit of teflon tape or paste to make sure you do not get any oil leaks.

It's not difficult to replace PCV valve!

PCV Valve Operation: A vacuum-controlled metering device that regulates the flow of crankcase fumes in the positive crankcase ventilation system by allowing more flow at high speed than at low speed, and acts as a system shutoff in case of engine backfire to prevent an explosion in the crankcase.
Depending on your engine size, the PCV is a different style and slightly different location.

Usually they are mounted in a hole on your valve cover.... connected by a vacuum tube.
Some are mounted with threads into the engine block (usually by the oil filter)

On the '04 Crv - it is nearly inaccessible behind the AC compressor and beneath what looks like an old vacuum advance. Most PCV valves today do not need to be replaced, unless there is actual valve failure, which I have not seen happen. I would not be concerned about replacing it.

Thanks for using FixYa - a FixYa rating is appreciated!!

The valve is inside the breather tube itself. [email protected]
