Default Re: PCV VALVE SYSTEM for 8BA with Early Intake Manifold

I think you misunderstand how this is plumbed. The air is drawn down through the filler tube vent into the crankcase, then up through the old original fill tube at the front of the block, across the valve chamber area back to the rear of the block, then up through the pcv valve, out through the spacer block and into the manifold.

The line from the fill tube at the front of the engine to the pvc valve is sealed. No way for the pcv to draw air anywhere EXCEPT from the crankcase.

Do I look like I have a plan B?
