Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool and the vehicle is parked on a level surface.
Disconnect the battery for safety if working on electrical components.

2. Inspect and Tighten Components

Tools Required: Socket set, torque wrench.
Remove any engine covers if necessary for access.
Check the tightness of the oil filter and drain plug; tighten if loose.
Inspect the valve cover bolts for proper torque (typically around 7-10 Nm); retighten if required.

3. Replace Worn Seals or Gaskets

Tools Required: Gasket scraper, RTV sealant, new gaskets.
Remove the valve cover or any component blocking access to the leaking seal.
Clean the surfaces thoroughly with a gasket scraper.
Apply RTV sealant if required, and replace the gasket.
Reinstall components and torque to manufacturer specifications.

4. Change Engine Oil and Filter

Tools Required: Oil filter wrench, oil catch pan, funnel.
Place the oil catch pan under the engine and remove the drain plug to drain the oil completely.
Replace the oil filter using the oil filter wrench.
Install a new drain plug with the appropriate torque (typically around 25 Nm).
Fill the engine with new oil that meets manufacturer specifications (typically 5W-30 synthetic oil).
