What is the primary purpose of a seal in an oil system?

• A. Reduce engine compression
• B. Increase oil temperature
• C. Prevent oil from escaping its normal path of flow
• D. Allow oil to spill out

Answer: (C)

Seals in an oil system are there to keep the lubricant where it is supposed to go. By sealing joints and interfaces, they prevent oil from leaking out of the designed flow paths, ensuring the oil reaches all bearings and components at the correct pressure and volume. This containment maintains proper lubrication, avoids contamination entering the system, and prevents oil loss that could lead to reduced lubrication, overheating, or wear. So the primary purpose is to prevent oil from escaping its normal path of flow. The other options describe outcomes of leaks or unrelated effects, not the function of the seal itself.
