Obstructed Oil Pressure Gauge Line Repair
Perform the following steps to resolve oil pressure gauge line obstructions:
- Remove oil pressure gauge line; refer to OEM guidelines.
- Clean oil gauge line by soaking in cleaning solution for five minutes.
- Blow out residue contamination in oil gauge line with compressed air.
- Install cleaned oil gauge line; refer to OEM guidelines.

Test the Engine with Repaired Oil Gauge Line
To determine if repaired oil pressure gauge line resolved low oil pressure, perform the following steps:
To avoid injury before starting and running the engine, ensure the vehicle is parked on a level surface, parking brake is set, and the wheels are blocked.
- Start and run the engine at rated speed. If the oil pressure at rated speed is 241 kPa (35 psi) or more, no further troubleshooting in required. Shut down the engine.
- If the oil pressure at rated speed is less than 241 kPa (35 psi), shut down the engine. Check for restricted oil cooler element; refer to "15.6 Restricted Oil Cooler Element" .
