Question

Two technicians are discussing cylinder leakage test results.Technician A says that 5% leakage past the exhaust valves is acceptable. Technician B says that all piston rings will leak at least 10% Who is correct? a. Technician A b. Technician B C c. Both Technician A and Technician B d. Neither Technician A nor Technician B Clear my choice

Answer 1

The correct answer is d. Neither Technician A nor Technician B.Technician A's statement that 5% leakage past the exhaust valves is acceptable is incorrect. In general, any significant leakage past the exhaust valves during a cylinder leakage test indicates a problem with the engine's valve seals or piston rings. Leakage past the exhaust valves can lead to reduced engine performance, increased emissions, and potential damage to the engine components.Technician B's statement that all piston rings will leak at least 10% is also incorrect. The acceptable level of leakage past the piston rings can vary depending on the engine design and the condition of the piston rings. In general, a small amount of leakage past the piston rings is considered normal, but excessive leakage can indicate worn or damaged piston rings that may require replacement.Therefore, neither Technician A nor Technician B is correct in their statements.
