The OP asked if it was normal that oil was building up in the intake tract. Its not caused by the PVC valve. the PVC emptys directly into the intake manifold. You will notice this when u take the intake manifold off, it will be very oily and gunky. Same with the throttle body and this is why u need to clean these parts more often when shitty oil is used. It breaks down and contaminates everything.

The PVC valve is actually attached to the STOCk oil catch can. This is a little black box located under the intake manifold. The implemetation is a little raw, but it gets the job done ALONG with the breather in the valve cover.
