Possible Causes

Loose or damaged oil filter, Worn crankshaft seals, Sump gasket leak, Loose oil drain plug

How to Fix / Troubleshooting

Safety: Clean up spilled oil promptly to prevent slips. Do not run the engine with low oil level.

  • Locate leak source: Clean the engine exterior and run briefly while observing for fresh oil. Use a flashlight to inspect around the filter, sump, and seals.
  • Filter and plug: Tighten the oil filter by hand plus the recommended fraction of a turn. Check the drain plug for tightness and replace its washer if seeping.
  • Gaskets and seals: If oil is coming from the sump gasket or crank seals, plan for gasket or seal replacement, which may require engine removal.
  • Top up oil: Restore oil to the correct level and monitor for further leakage.
