I was looking at the vacuum wiring diagram under the hood of the 8 and it shows a pcv valve. I didnt think the 8 had a pcv valve! Does anyone know where this is located? thanks.

i am pretty sure the 06 has one. as to where i have no idea.

There is a vastly different crankcase ventilation system in the 2006's. There is a one way valve where the system vents into the manifold. The breather goes from the vent by the oil fill tube to the vacuum ports on the passenger side of the engine. The vent from the TB end goes to the manifold by the oil filter...

I think Mazda learned something, didn't they

Well the one that I have is a 2005. If anyone has a 05 you can see it on the diagram under the hood. So the 06's are different from my 05?

Where did you get the diagram from? Could you show me?

My understanding is that valve has only come in the 2006 model?

my brother has my digi camera, but it is on the underside of the hood on the left top right beside the emissions info.

What would be the benefits from this change in the way the vaccum line are routed.

less "milky stuff on the dipstick" threads on the forum is the major benefit to me and my sanity. the othe rbnefit to the 8 owners is less or no oil getting into the intake accordian tube and screwing around with the MAF among other things
