This is a DIY for replacing your PCV valve. I figured why the hell not right ? Someone might find this useful ? Plus, I'm bored. HAH

Tools needed:
17mm Wrench + Another larger wrench
3/8 Ratchet
Short Extension
17mm Deep Well Socket


This picture shows you the location of your PCV Valve.


This is just a close up of the PCV Valve. Now take your pliers and pull back the clamp closest to the head.


This is how it should look once you have pulled it back.


If you struggle with loosening the rubber hose, try using your pliers and twisting the hose back and forth. This technique should break the seal allowing you to pull the hose back with ease. Once you have removed the first clamp and hose, do the same with the other clamp connecting the rest of the hose to the intake manifold.


The PCV valve is 17mm. So you will need a 17mm wrench and another larger size wrench. When you combine the two, you have a breaker bar of sorts. This picture shows you how it should look.



After you have broken the PCV valve loose, you can use your 3/8 ratchet, small extension, and 17mm deep well socket to speed up the process. Though I do not recommend using this set up to loosen the PCV valve. It appears to be on straight, but after looking at it closely it puts you at an angle. Putting you at risk for rounding off the nut, which is something you do not want to do.



This picture shows the hole where your PCV goes. After you have taken out your PCV valve repeat the steps above in reverse.



Here's a picture of the old PCV valve and the part number for a new one. If you need it ;)

Nice DIY,

How important is that thing? I'm thinking of taping out the PCV valve and just putting a breather filter on it.
Do the words crankcase pressure mean anything to you Mark?

My 02 has 127xxx miles on it. I figure it was about time to change out. At the dealer the price is 31.41 but with the home boy hook-up 18.45.

The PCV valve is a control device which sends partially burned gases that come from the engine's crankcase to the combustion chamber. Its name, PCV means Positive Crankcase Ventilation and is one of the oldest and most used emission control devices. Although its name might sound very complicated, it is a very simple device and its function can be easily understood.

Due to its tasks, the PCV valve is not only very useful but also implies important benefits. It completely eliminates crankcase emissions efficiently, avoiding that it becomes an air pollution factor. Besides, it also keeps the system free of moisture due to the constant air circulation that it implies.

Besides, the PCV valve also helps keeping the oil and the engine in proper shape extending their life as well. Also, its mechanism is very important for preventing the appearance of engine corrosion as well as it helps improving fuel economy. This way, the PCV valve is very important for different aspects and helps car owners maintaining their car’s engines in shape as well as providing them with a good administration of the fuel economy

The PCV valve routes crankcase partially burned gases back to the engine. Once these gases go back to the engine, they are re-burned, allowing this way a better use and administration of fuel. The cylinders are an important part in the process since they are who re-burn the gases rerouted from the PVC valve and have a central role in it.

Crankcase emissions can be a great source of air pollution, and therefore the PCV valve is very useful and important not only for the car functioning but also for the environment and health as well. Besides, this valve requires little maintenance and must be replaced at about 40.000 miles. This way, the PCV valve is an easy to maintain piece which implies an important amount of benefits that affect not only the car and its owner but also those who surround him and the environment in general due to the way in which it prevents gases from becoming air pollution factors.

Doesn't need replacing unless the check valve inside gets stuck.

You'll notice poor performance if it gets stuck, as the crankcase won't be able to ventilate.

And, even if it does get stuck, soaking it in brake cleaner will fix it.

there is no periodic replacement interval in the maint. schedule, unlike many other cars.

Helms:

At idle, make sure there is a clicking sound from the valve when the hose between the valve and IM is lightly pinched. If there is no clicking sound, check the grommet for cracks or leaks. If grommet OK, replace valve and recheck.

I'm one who likes to replace things before they go bad. Call me crazy :run:

Nice DIY, thanks for posting. Generally, if you can shake the PCV valve and it rattles, it is fine. FYI, there is an OEM substitute available at Autozone for about $16 if you don't feel like going to the dealership.
