Solution

1. Preparation

Gather tools and parts needed for the repair.
Ensure the engine is cool before commencing work.
Disconnect the battery to prevent electrical shorts.

2. Identify and Repair Oil Leaks

Inspect Seals and Gaskets:
- Remove any components blocking access to the oil seals and gaskets (if necessary).
- Inspect the valve cover gasket, oil pan gasket, and crankshaft seals for wear or damage.
Replace Damaged Gaskets/Seals:
- If any gaskets or seals are found damaged, remove the old gasket material from the surfaces.
- Clean surfaces with a solvent and apply a new gasket or sealant per manufacturer specifications.

3. Address Oil Filter and Drain Plug

Inspect and Replace Oil Filter:
- Use an oil filter wrench to remove the oil filter. Inspect for debris or damage.
- Apply a thin layer of oil to the rubber gasket of the new filter and install it, tightening according to specifications (usually ¾ of a turn after contact).
Check Drain Plug:
- Inspect the oil drain plug for tightness and condition. Replace the washer if necessary. Tighten to manufacturer specifications.

4. Clean and Reassemble

Clean Engine Bay:
- Use a degreaser to clean any oil residue in the engine bay.
- Allow the area to dry completely.
Reassemble Components:
- Reinstall any components removed for access.
- Reconnect the battery and ensure all connections are secure.
