Solution

1. Preparation

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

2. Inspect and Repair Leaks

Tools Required: Socket set, wrench set, oil catch pan.
Place the oil catch pan under the vehicle to catch any leaking oil.
Inspect the oil pan, valve cover, and oil filter for leaks.
Tighten any loose bolts on the oil filter or valve cover.
Replace the oil filter if damaged or improperly installed.

3. Replace Oil

Tools Required: Oil catch pan, funnel, socket set.
Drain the old oil using the oil catch pan by removing the oil drain plug; allow it to fully drain.
Replace the oil drain plug and tighten to the manufacturer's torque specifications (typically around 20-25 lb-ft).
Add new oil through the oil filler cap, using the manufacturer-recommended oil type (usually 5W-20 or 0W-20 for CR-Vs).
Check the oil level with the dipstick after adding oil, ensuring it reaches the proper level.

4. Inspect and Clean PCV System

Tools Required: Pliers, cleaning solvent.
Locate the PCV valve (usually on the valve cover or intake manifold).
Remove the PCV valve and inspect it for blockage.
Clean or replace the PCV valve as necessary.
