Answer:Both Technician A and Technician B are right.

Explanation: The cracks in an engine can be detected when the engines are thoroughly cleaned because the transmission vent is basically designed to vent hot air.

Also pressure testing can equally detect cracks easily. When you increase the pressure,you will notice leaks from the blocks or cylinder indicating a crack on them.
