| Troubleshooting Test Steps | Values | Results |
|---|---|---|
1. Low Engine Oil Level A. Check the engine oil level in the crankcase. |
Oil level | Result: The engine oil level is low. Repair: Add engine oil in order to obtain the correct engine oil level. Refer to Operation and Maintenance Manual, "Engine Oil" for the recommendations of engine oil. Start the engine. Inspect the exterior of the engine for oil leaks. Repair any oil leaks. Verify that the repair eliminated the problem. Note: If you suspect that the engine is consuming an excessive amount of engine oil, refer to Troubleshooting, "Oil Consumption Is Excessive". Result: The engine oil is not low. Refer to Troubleshooting, "Oil Level - Test" for troubleshooting information. |
