- Remove old gaskets using a scraper, ensuring no debris falls into the engine.
- Clean the gasket surfaces thoroughly with a solvent.
- Apply a thin layer of gasket sealer if specified by the manufacturer.
- Install new gaskets in the correct orientation and torque to specifications.

3. Tighten or Replace Oil Drain Plug

Check Drain Plug
- Inspect the oil drain plug for wear or damage.
- If loose, tighten to the manufacturer's torque specification.
- If damaged, replace with a new drain plug.

4. Inspect and Replace Oil Filter

Remove Old Oil Filter
- Use an oil filter wrench to remove the oil filter.
- Allow any residual oil to drain into a container.
Install New Oil Filter
