A cylinder leakage (leak-down) test indicates 30% leakage, and air is heard coming out of the air inlet. Technician A says that this is a normal reading for a slightly worn engine. Technician B says that one or more intake valves are defective.
What checks can be performed to know if the lubricating oil of an engine has been contaminated?
Technician A says that liquid cooling an engine helps to maintain a consistent operating temperature. Technician B says that oil is circulated through the cooling system to remove heat from the engine's parts. Who is correct?
