Pcv valve

[Alex Bland]

im changeing the valve cover gasket so i removed the pcv valve shook it (it ratteled) so i was like cool ok its fine.. So then i just thought maybe ill blow in it to make sure and i can blow and suck air threw it just fine..my car idles fine should i replace it? also could this be the reason why i see my smoke from exhaust at night and it has a tint of blue in it? maybe this could fix it

It it isnt stuck,then you dont need to replace it.

i thought air is only suppost to be able to come in from one direction though

If it works fine (air can only get through one way), then you don't need to. If you haven't in a while, it might be worth it as it's a cheap part.

just clean it with some brake cleaner. then grab a us plastics check valve

i think ill just replace it sence i just cleaned it and it moves a little more and air is still going in both ways i might as well.

If air goes through both ways, even just a little bit, then it needs replaced.

And I'd also recommend the above suggestion of a US Plastics check valve. Search around if you're not sure what we're talking about.

Get a Mitsubishi pcv valve. The cheap ones were not designed for boosted cars.
