• The PCV (Positive Crankcase Ventilation) system recirculates blow - by gases (not exhaust gases) from the crankcase into the intake manifold. So Technician A is wrong.
• There are three common types of PCV systems: the orifice - type PCV system, the fixed - orifice PCV system with a check valve, and the balanced PCV system. So Technician B is correct.

b. Technician B
