Solution

1. Preparation

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

2. Replace Oil Filter

Tools Needed: Oil filter wrench, oil catch pan.
Sub-steps:
1. Place the oil catch pan under the oil filter.
2. Use the oil filter wrench to remove the old oil filter. Allow excess oil to drain into the pan.
3. Apply a small amount of clean oil to the rubber O-ring of the new oil filter.
4. Install the new oil filter by hand, tightening it until snug, then give it an additional 3/4 turn.

3. Replace Front Crankshaft Seal

Tools Needed: Socket set, seal puller, hammer, and a new crankshaft seal.
Sub-steps:
1. Remove any components obstructing access to the front crankshaft seal (e.g., belts, pulleys).
2. Use a seal puller to carefully remove the old crankshaft seal.
3. Clean the sealing surface on the engine block.
4. Apply a thin layer of engine oil to the new seal's lip.
5. Carefully tap the new seal into place using a hammer and a suitable tool to avoid damaging it.

4. Inspect and Replace Gaskets

Tools Needed: Gasket scraper, torque wrench, new gaskets.
Sub-steps:
1. If leaks are suspected from the valve cover or oil pan gaskets, remove the respective components.
2. Scrape off old gasket material from both surfaces using a gasket scraper.
3. Place new gaskets in position, ensuring proper alignment.
4. Reinstall components and torque bolts to the manufacturer's specifications.
