1. Preparation

Gather tools and safety equipment.
Tools required:
- Socket set
- Oil filter wrench
- Torque wrench
- Oil catch pan
- Clean rags
Safety warnings:
- Allow engine to cool before beginning work.
- Disconnect the battery to prevent electrical issues.

2. Addressing Gasket Issues

If leaking from the valve cover gasket:
1. Remove any components obstructing access to the valve cover.
2. Unbolt the valve cover using the socket set.
3. Remove the old gasket and clean the mating surfaces with a scraper.
4. Install a new gasket, ensuring it's seated properly.
5. Reinstall the valve cover and torque bolts to manufacturer specifications (typically 7-11 ft-lbs).
If leaking from the oil pan gasket:
1. Raise the vehicle securely on jack stands.
2. Drain engine oil into the oil catch pan.
3. Remove the oil pan by unbolting it with the socket set, taking care not to damage it.
4. Clean the oil pan and engine block surfaces thoroughly.
5. Install a new oil pan gasket and reattach the oil pan, torquing bolts to specifications (usually 7-9 ft-lbs).

3. Replacing Seals

If the front crankshaft seal is leaking:
1. Remove the harmonic balancer using a puller tool if necessary.
2. Carefully pry out the old crankshaft seal.
3. Lubricate the new seal with engine oil and install it carefully, ensuring it's flush with the engine block.
4. Reinstall the harmonic balancer and torque to the manufacturer's specifications.

4. Final Steps

Refill the engine with the appropriate type and amount of oil as specified in the owner’s manual.
Start the engine and check for leaks after the repair.
