The basic concept of any forced induction system is to put more oxygen into the combustion chamber. More air in the engine means more power at the crankshaft. But, pressurizing the intake manifold means vacuum is replaced by pressure. This creates problems for managing vapors and pressure in the crankcase.

When an engine is turbocharged, the intake manifold is under pressure during most running conditions. The gas and oil bypassing the rings are still present. And, the pressure generated by the turbocharger can increase crankcase pressures. That’s when a more advanced PCV system is required. In this video, we discuss how these systems work, and how some systems use heated PCV valves to keep the system operating during start up.  This video is sponsored by Elring.
