ABSTRACT:
An integrated positive crankcase ventilation (PCV) channel is formed along a structural weld line between two shell components that are welded together to form an air intake manifold. The integrated PCV channel can be used to uniformly distribute blow-by gases from the crankcase of an internal combustion engine to a plurality of combustion chambers via the air intake manifold.
