Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety during repairs.
Allow the engine to cool before starting any work.

2. Identify and Repair Oil Leaks

Inspect Gaskets and Seals:
- Remove any plastic engine covers if applicable.
- Inspect the valve cover gasket, oil pan gasket, and rear main seal for leaks.
- Replace any damaged gaskets or seals with new ones.
- Torque all bolts to manufacturer specifications.
Check Oil Filter and Drain Plug:
- Use an oil filter wrench to remove the oil filter; inspect for leaks around the filter.
- Ensure the drain plug is snug; replace the crush washer if necessary.
- Install a new oil filter, lubricating the rubber gasket with a bit of oil before installation.

3. Change Engine Oil

Drain Old Oil:
- Place an oil catch pan under the oil pan.
- Remove the drain plug and allow the old oil to completely drain.
- Replace the drain plug and tighten to the specified torque.
Add New Oil:
- Use the manufacturer-recommended oil type and viscosity.
- Pour new oil through the oil filler cap, checking the level with the dipstick as you fill.
- Start the engine and let it run for a minute, then check for leaks around the oil filter and drain plug.
