Chip detectors are placed in which path?

• A. In the oil supply lines.
• B. In the scavenged oil path.
• C. In the fuel line.
• D. In the crankcase vent line.

Answer: (B)

Chip detectors monitor metal debris in the engine’s lubrication system to give an early warning of abnormal wear. They’re placed in the scavenged oil path—the return line that takes oil drained from the crankcase and engine components back to the oil tank. This location carries oil that has already picked up any wear particles from bearings and gears, so a sensor here can detect debris before the oil is circulated again through the engine. Placing a detector in the oil supply line wouldn’t be as effective for early warning, and the oil supply line is designed primarily to deliver clean, pressurized oil. The fuel line isn’t involved with lubrication, and the crankcase vent line mainly handles gas venting, not oil containing metal chips.
