Solution

1. Preparation

Tools Required:
- Socket set
- Oil filter wrench
- Torque wrench
- Oil catch pan
- Clean rags
Safety Warnings:
- Allow the engine to cool before working on it.
- Ensure the vehicle is parked on a level surface.

2. Inspect and Tighten Oil Filter

Locate the oil filter and use the oil filter wrench to check if it is properly tightened.
If loose, tighten the filter by hand until snug (avoid over-tightening).
If damaged, remove the filter completely, clean the mounting surface, and replace it with a new filter.

3. Check Oil Drain Plug

Using the socket set, ensure the oil drain plug is tightened to the manufacturer’s specification (usually 20-25 lb-ft for Honda).
If leaking, remove the plug, inspect the washer for damage, and replace if necessary. Reinstall the plug and torque to specifications.

4. Inspect Oil Pan Gasket

If the leak persists, check the oil pan gasket for any signs of damage or deterioration.
If damaged, drain the oil and remove the oil pan by unbolting it from the engine block.
Clean the mating surfaces thoroughly, apply a new gasket or sealant, and reassemble the pan, torquing the bolts to the manufacturer's specifications (usually around 8-10 lb-ft).

5. Inspect Oil Lines and Seals

Examine any visible oil lines and seals for leaks.
Replace any damaged seals or lines as necessary, ensuring a proper fit and seal.

6. Refill Engine Oil

Refilling the engine with the correct type and amount of oil after repairs.
Start the engine and let it run for a few minutes while checking for leaks.
