Here's a topic I haven't seen.
PCV - I usually take 'er off and shoot a little carb cleaner in it and let her rip. But after a 80K I'm thinking replace.
Any thoughts.

Yeah Im going up to get an air filter anyway so I think I'm just going to go ahead get a PCV too.
Trying to get alot done under the hood before the wintery mix hits. Just had a light snow yesterday but no accumulation.
The below freezing weather seems to make things stick sometimes.

Cleaning & Rattling is good but with it off and connected, with KJ running, place your thumb over the bottom of it, and you should feel a powerful suction.

Another one of those things that are cheap and easy to replace but most don't. The time and money it takes to clean one you can replace in my book
Its like spark plugs
I change mine out every 25000/30000 miles at least most times every time I swap spark plugs which is every 25000.
But then at 150000 miles miles when I get ready to go somewhere I don't have to worry , what should I change or check.
Its always ready at a moments notice :emotions33:

$6 and change at NAPA. I just changed mine. The old one still looked good so I saved it. I guess I got a spare if I feel like cleaning it out. It still rattles..If not I'll just get another if I need one.

The replacement I got from Auto Zone was aweful. Only place open locally when I went out.
The part is just enough off to not fit. You'd have to shave the tab width, cut a 16th off the length at the nose so it would seat for the tab lock - that was too wide....and the tube inside was 2/3rds the size of the original....
Aftermarket ..........got to love it.
Napa or the dealer Monday.

You men Auto Moan......haha

The NAPA one I got was the exact same as the OEM one. I have changed it several times now. They fit tight though but so didn't the OEM one. For whatever it's worth.

Nothing wrong with tight as long as fits correctly and you don't force it and break some plastic...:angry94:
Napa sounds good to me.

The long story
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 PCV 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.
