Solution

1. Preparation

Gather tools and materials: rags, oil catch pan, socket set, new oil and filter, torque wrench.
Ensure the engine is cool and the vehicle is parked on a level surface.
Disconnect the battery if working on electrical components.

2. Address Oil Leak

Step 1: Clean the engine area with an engine degreaser to identify the source of the leak.
Step 2: Tighten any loose bolts on the oil pan and valve cover using a torque wrench to manufacturer specifications (typically around 15-25 ft-lbs).

3. Replace Oil Filter and Oil

Step 1: Place an oil catch pan under the oil pan.
Step 2: Remove the drain plug and allow the oil to fully drain.
Step 3: Replace the oil filter using an oil filter wrench, ensuring to lubricate the new filter’s rubber gasket with fresh oil.
Step 4: Reinstall the drain plug and torque to specifications (around 20-25 ft-lbs).
Step 5: Fill the engine with new oil through the filler cap, using the recommended oil type (consult the owner’s manual, typically 5W-30 or 0W-20).

4. Inspect and Clean PCV System

Step 1: Locate the PCV valve and remove it for inspection.
Step 2: Clean the PCV valve and its hose with carburetor cleaner if clogged.
Step 3: Reinstall the PCV valve ensuring a snug fit.

5. Reassemble and Test

Step 1: Reconnect the battery.
Step 2: Start the engine and let it idle while checking for leaks and the burning smell.
Step 3: Monitor the oil pressure gauge to ensure proper function.
