Abstract
An internal combustion engine includes a plurality of PCV ports formed internally within the engine block and the cylinder head. The PCV ports directly connect a crankcase chamber with each of a plurality of intake ports defined by the cylinder head. The blow-by gases that accumulate within the crankcase chamber are directly vented through the internal PCV ports into the intake ports.
