Air intake assembly with integrated crankcase ventilation system

An engine assembly comprising:

• an engine block including a first bank defining a first set of cylinders;
• a first cylinder head fixed to the first bank and including a first set of intake ports;
• and
• an air intake assembly including:
• an intake air tube in communication with the first set of intake ports and an air source;
• a crankcase ventilation housing integrally formed with the intake air tube and having a wall at least partially defined by the intake air tube, the wall being in thermal communication with the intake air tube and the crankcase ventilation housing to transfer heat from an air flow through the intake air tube to the crankcase ventilation housing;
• and
• an oil separation assembly located within the crankcase ventilation housing and adapted to remove oil from air passing through the crankcase ventilation housing.

An engine assembly comprising:

• an engine block including a first bank defining a first set of cylinders;
• a first cylinder head fixed to the first bank and including a first set of intake ports;
• a first cover member fixed to the first cylinder head and defining a cam cover portion and an intake manifold portion, the cam cover portion being in communication with engine crankcase gases and the intake manifold portion being in communication with the first set of intake ports;
• and
• an air intake assembly including:
• an intake air tube in communication with the intake manifold portion of the first cover member and an air source;
• a crankcase ventilation housing integrally formed with the intake air tube and having a wall at least partially defined by the intake air tube, the wall being in thermal communication with the intake air tube and the crankcase ventilation housing to transfer heat from an air flow through the intake air tube to the crankcase ventilation housing;
