1.5T Bad PCV valve?

[kytos]

Hi all,

I noticed a werd noise under the valve cover and I've finally found a clue. The noise appears randomly and if I press the tube that goes from the valve cover to the intake manifold it shuts up.



What should I do? I think it's the check valve?

In case anyone notice the same behaviour I replaced the PCV valve and the noise is gone. The valve wasn't too bad but It was getting stuck open sometimes.

Right, the manual says the check that way.
