Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid any electrical issues.

2. Inspect and Replace Oil Filter

Remove the old oil filter using an oil filter wrench.
Check the rubber O-ring on the old filter for damage; replace if necessary.
Install the new oil filter, tightening it to hand-tight plus a quarter turn.
Ensure the filter is seated properly to prevent leaks.

3. Inspect and Repair Oil Pan Gasket

Drain the engine oil using a drain pan.
Remove the oil pan by unscrewing the bolts with a socket set (torque specifications: 8-10 Nm).
Clean the mating surfaces of the oil pan and engine block with a suitable solvent to remove old gasket material.
Apply a new gasket or gasket sealant as per manufacturer's specifications.
Reinstall the oil pan, tightening the bolts in a crisscross pattern to the specified torque.

4. Check and Tighten Seals

Inspect valve cover gaskets and seals for any signs of wear or damage.
Tighten any loose bolts on the valve cover and replace gaskets if necessary.

5. Refill Engine Oil

Pour the recommended type and amount of engine oil (typically 5W-30) into the engine.
Start the engine and let it run for a few minutes, checking for leaks around the oil filter and oil pan.
Recheck the oil level with the dipstick and add oil if necessary.
