Question

technician a says that the pcv system removes blowby gases from the crankcase in a manner that is not harmful to the environment. technician b says that the pcv system prevents the buildup of crankcase pressure. who is correct?

a. technician a
b. technician b
c. both technician a and technician b
d. neither technician a nor technician b

Explanation:

The PCV (Positive Crankcase Ventilation) system recirculates blowby gases back into the intake manifold for combustion, which is environmentally friendly as it reduces emissions. Also, it prevents crankcase pressure buildup by allowing gases to escape in a controlled way. So both Technician A and Technician B are correct.

Answer:

c. Both Technician A and Technician B
