Solution

1. Preparation

Tools Required: Socket set, torque wrench, oil catch pan, rags, O-ring pick, engine oil, new oil filter.
Ensure the engine is cool and the vehicle is on a level surface.
Disconnect the battery for safety.

2. Locate and Address the Leak Source

Check Oil Filter:
- Remove the old oil filter using an oil filter wrench.
- Inspect the O-ring on the filter for damage; replace if necessary.
- Apply a thin layer of new engine oil to the new filter O-ring before installation.
- Install the new oil filter by hand-tightening it and then tightening it an additional 3/4 turn with the wrench.
Inspect and Replace Drain Plug:
- Place an oil catch pan under the oil pan.
- Remove the drain plug using a socket wrench.
- Inspect the drain plug and gasket for wear; replace if damaged.
- Clean the area around the drain hole and install the new or cleaned drain plug, torque to manufacturer specifications (typically 25-30 Nm).
Oil Pan and Gasket Repair:
- If the oil pan is cracked, it will need to be replaced.
- To replace the oil pan, drain the oil completely, remove the oil pan bolts, and carefully remove the oil pan.
- Inspect the oil pan gasket; if damaged, replace it with a new gasket.
- Reinstall the oil pan by reversing the removal process, ensuring all bolts are torqued to specifications.

3. Refill Engine Oil

After completing repairs, refill the engine with the appropriate type and amount of engine oil as specified in the owner’s manual.
