V6 Engine PCV / Blow-By Gas Flow Schematic - Crankcase Ventilation Diagram

This document is a schematic diagram of a positive crankcase ventilation (PCV) / blow-by gas flow system for a V6 engine. The left portion shows a cutaway of the engine with labeled components: cylinder head cover, oil separation area, cylinder head, piston, connecting rod, cylinder block, and oil pan. The right portion shows the ventilation circuit at the throttle body and surge tank (RH side), with labeled Ports A, B, and C, airflow arriving from the air cleaner, flow directed to the intake manifold, and two labeled hoses (Ventilation Hose 1 and Ventilation Hose 2). Directional arrows distinguish fresh air flow (open arrows) from blow-by gas flow (solid arrows), showing fresh air entering the crankcase circuit and blow-by gases being routed via the oil separator and ventilation hoses back into the intake system. A reader can learn the routing path of crankcase gases, which ports on the throttle body/surge tank the ventilation hoses connect to, and where oil separation occurs in the cylinder head cover. The diagram contains no part numbers, torque specifications, model designations, or year information, it is purely a flow/routing schematic.
