Pcv ??

OK. I am a bit confused between the two items...a pvc and a breather.

Neither of my valve covers have a hole for either.

I do have a breather - part # p4120446.

Should I buy 2 pvc and put one on each valve cover or one pvc and one breather ?

Neither of my brit cars had either though one had a stink pipe which came off the valve cover and was run under the car..maybe an early pvc valve :)

Thanks
Ian.
