Recently the car smokes (blue) when we start it up and goes away after warming up. I have been told this could be the PCV valve.
Could any one confirm this and where is it situated?

Any help appreciated. Cheers, Steve.

Hello, I am Danny.

Yes, it is possible your PCV valve could be plugged or stuck. I have attached a tutorial for you and a picture of its location. Hope this helps and thanks for using 2CarPros.

Hi Danny, thanks for you information I have purchased A PCV valve today I will change it tomorrow.

But I had a look at the top end of our 2010 Kia Picanto yesterday and I unscrewed the valve from the back end of the rocker cover with the rubber hose connected that goes to the intake manifold it did not rattle but I could blow through it both ways.

Is that normal? Cheers, Steve.

Hello Steve,

No. A PCV valve is a check valve. Should only be able to have air blow through in only one direction. Hope this helps and thanks again for using 2CarPros.
