- Using an oil filter wrench, remove the oil filter.
- Check the old filter's rubber gasket for damage; replace if necessary.
- Apply a thin layer of new oil on the gasket of the new oil filter.
- Install the new oil filter by hand, ensuring it is snug but not overtightened.

3. Replace Front Crankshaft Seal

Sub-steps:
- Remove any components obstructing access to the crankshaft seal (like the timing cover if necessary).
- Use a seal puller to carefully remove the old crankshaft seal.
- Clean the sealing surface on the engine block.
- Apply a small amount of engine oil to the new seal’s edge to facilitate installation.
- Press the new seal into place using a seal installation tool or a suitable socket.

4. Address Valve Cover Gasket

Sub-steps:
- Remove the valve cover by loosening the bolts with a socket set.
- Carefully lift the valve cover off and remove the old gasket.
- Clean the mating surfaces on the valve cover and cylinder head.
- Install the new gasket and reassemble the valve cover, tightening the bolts to the specified torque.

5. Refill Engine Oil
