The correct answer is d. Neither Technician A nor Technician B.<br /><br />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.<br /><br />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.<br /><br />Therefore, neither Technician A nor Technician B is correct in their statements.
