1996 Ford Contour Cam cover ventilation

we have no pictures of this so you'll have to look around it may b to the air duct going into throttle as its' a crankcase breather.

Thanks hmac300 for your reply!

I already did that, connect this vent to air intake duct, like the other hose, but the engine gets accelerated and when you remove oil cap, you may heard a pressure release.

then have your pcv valve checked to see if it's blocked or not. it may be vacuum you arehearing as well.

Hi.

I put a new PCV valve and connect both cam cover hoses to air duct, engine is working smooth but a little bit accelerated, it stays at 1100-1200 rpm. Is it normal?

And your are right, what I heard is vacuum. That's what it should be?

Thanks again. Regards.

sounds about right but clean your throttle plate on both sides it may be a little sticky. and the idle will go down.
