Solution

1. Preparation

Gather tools and materials needed for the repair.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery for safety.

2. Address Oil Leaks

Sub-step 1: Remove any engine cover if applicable (tools: socket set).
Sub-step 2: Inspect the valve cover gasket; if leaking, remove the valve cover (tools: socket set, torque wrench).
Sub-step 3: Clean the mating surfaces with a scraper and ensure no debris is left.
Sub-step 4: Replace the valve cover gasket with a new one (parts: valve cover gasket).
Sub-step 5: Reinstall the valve cover and torque to manufacturer's specifications (typically around 10-12 Nm).

3. Replace Oil Filter and Oil

Sub-step 1: Drain the engine oil using an oil catch pan (ensure the oil is warm for better flow).
Sub-step 2: Remove the old oil filter (tools: oil filter wrench).
Sub-step 3: Install the new oil filter (parts: oil filter) and lubricate the gasket with clean oil.
Sub-step 4: Refill the engine with the recommended oil type (parts: engine oil, typically 5W-30 or as specified).
Sub-step 5: Run the engine for a few minutes and check for leaks.
