Solution

1. Preparation

Gather tools and parts, including an OBD-II scanner, compression tester, socket set, and new oil/filter.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery for safety.

2. Perform Compression Test

Step 1: Remove the spark plugs using a socket set.
Step 2: Attach the compression tester to the first cylinder and crank the engine.
Step 3: Record the compression reading; repeat for each cylinder.
Step 4: Compare readings; a significant drop in one or more cylinders indicates internal wear.

3. Inspect and Replace PCV Valve

Step 1: Locate the PCV valve (typically on the valve cover).
Step 2: Remove the valve and inspect for clogging or damage.
Step 3: Replace with a new PCV valve if necessary.
Step 4: Reinstall the valve ensuring proper sealing.

4. Check and Replace Oil Filter

Step 1: Raise the vehicle and secure it with jack stands.
Step 2: Remove the oil drain plug to drain old oil into a pan.
Step 3: Replace the oil filter using an oil filter wrench.
Step 4: Reinstall the drain plug and tighten to manufacturer's specifications (typically 20 lb-ft).

5. Add New Oil

Step 1: Use the manufacturer-recommended oil type and viscosity.
Step 2: Pour new oil through the oil filler cap using a funnel.
Step 3: Start the engine and let it run for a few minutes; check for leaks.
Step 4: Recheck the oil level with the dipstick and add more if necessary.
