Solution

1. Preparation

Gather tools and materials: oil catch pan, socket set, torque wrench, new oil and oil filter, replacement gaskets/seals if necessary.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical issues during the repair.

2. Change Oil and Filter

Drain the Old Oil
- Place an oil catch pan under the oil pan.
- Remove the drain plug with a socket wrench and allow the oil to fully drain.
- Replace the drain plug and torque it to the manufacturer's specification (typically around 20-25 ft-lbs).
Replace Oil Filter
- Locate the oil filter and use an oil filter wrench to remove it.
- Apply a thin layer of new oil to the rubber seal of the new oil filter.
- Install the new oil filter by hand, then tighten it according to specifications (usually hand-tight plus a quarter turn).
Add New Oil
- Remove the oil filler cap and pour in the recommended type of oil (refer to owner's manual for specifications).
- Replace the oil cap and run the engine for a few minutes to circulate the new oil.

3. Inspect and Replace Faulty Components

Inspect PCV System
- Remove the PCV valve from the valve cover.
- Check for blockages; replace if necessary.
Inspect and Replace Valve Seals (if necessary)
- Remove the valve cover using a socket set.
- Check the condition of the valve seals; replace them if they are worn.
- Reinstall the valve cover with a new gasket, torquing bolts to specifications.
Inspect and Replace Piston Rings (if necessary)
- Perform a more extensive engine disassembly to reach the piston rings.
- Replace the piston rings and reassemble the engine following manufacturer specifications.
