1. Preparation

Gather tools and materials.
Tools Required: Socket set, torque wrench, oil filter wrench, UV light, oil catch pan, rags.
Safety Warnings: Allow engine to cool before starting, and wear gloves to prevent skin contact with oil.

2. Identify and Repair the Leak Source

Oil Pan Gasket Replacement
1. Lift the vehicle using a jack and secure it with jack stands.
2. Drain the engine oil into an oil catch pan.
3. Remove the oil pan by unscrewing the bolts using a socket set.
4. Clean the mating surfaces of the oil pan and engine block.
5. Install a new oil pan gasket and torque the bolts to the manufacturer’s specifications.
Valve Cover Gasket Replacement
1. Remove any components obstructing access to the valve cover (e.g., air intake).
2. Unscrew the valve cover bolts and carefully lift off the cover.
3. Remove the old gasket and clean the surfaces.
4. Place a new gasket on the valve cover and reattach it, tightening bolts to specified torque.
Oil Filter Replacement
1. Locate the oil filter and use an oil filter wrench to remove it.
2. Apply a thin layer of oil on the rubber gasket of the new filter.
3. Install the new oil filter, hand-tightening it securely.

3. Refill Oil and Check for Leaks

Refill the engine with the appropriate type and amount of oil.
