Thanks a lot.

I changed yesterday, it looks good. But my PCV valve is about $24.00.

请问这个东西是在引擎盖下面的还是在车底盘下面的？ 我的车是99 mustang v6 /3.8L的。空挡停车的时候，变速杆抖的厉害，而且IDEL时高时低，有时不注意还会发生熄火事件，太丢人了。
我这车的PCV VALVE贵吗？哪里可以买到？是否一定要用FORD原厂的？请各位大哥帮我解答一下，谢谢了。

我下周去修车，想一起换了，大家早点告诉我啊。
再次感谢。

我想知道换这个东西，是不是先关掉引擎，然后换，然后在打火发动就OK了吗？还是有别的特殊步骤，我的车是旧车，没有说明书。郁闷！
换的时候需要断电吗？

询问过另外的师傅，说这个根本不用换啊，搂住能不能讲讲为什么换这个东东

you don't have to change it. But it draws back the air in the crankcase and reuses it in the combustion process & etc... spending 2 bucks to improve your idleing and fuel economy, why not!

it's basically a vaccum valve.

 

[你又何必伤我]

Definition of PCV: The Positive Crankcase Ventilation valve is an emissions control device that routes unburned crankcase blowby gases back into the intake manifold where they can be reburned. The PCV system is one of the oldest emission control devices, and also one of the most beneficial. Besides totally eliminating crankcase emissions as a source of air pollution, the constant recirculation of air through the crankcase helps remove moisture which otherwise would cause sludge to form. Thus the PCV valve extends the life of the oil and engine. The PCV valve requires little maintenance. The valve and filter should be replaced somewhere around 30,000 to 50,000 miles (see the vehicle owners manual for service intervals).
