Solution

1. Preparation

Tools Required: Socket set, wrench set, oil catch pan, clean rags
Raise the vehicle using a hydraulic lift or jack stands for safety.
Ensure the engine is cool and disconnect the battery.

Remove the oil filter using the oil filter wrench.
Apply a thin layer of oil on the new filter gasket.
Install the new oil filter, ensuring it is snug (hand-tight only).

2.2 Repair Oil Pan

Tools Required: Socket set, torque wrench
If the oil pan is cracked or damaged, remove it by unscrewing the bolts and gently prying it off.
Clean the mating surfaces with a solvent.
Apply a new gasket or RTV silicone sealant as recommended by the manufacturer.
Reinstall the oil pan, tightening the bolts to the specified torque (typically around 10-15 ft-lbs).

2.3 Replace Valve Cover Gasket
