Solution

1. Preparation

Tools Required: Socket set, torque wrench, oil catch pan, rags
Ensure the engine is cool and disconnect the negative battery terminal for safety.

2. Inspect and Replace Oil Filter

Sub-steps:
1. Place an oil catch pan under the oil filter.
2. Remove the old oil filter using an oil filter wrench.
3. Lubricate the rubber O-ring of the new oil filter with a small amount of new oil.
4. Install the new oil filter, tightening it by hand until snug (do not over-tighten).

3. Replace Valve Cover Gasket (if leaking)

Sub-steps:
1. Remove any components obstructing access to the valve cover (e.g., air intake, ignition coils).
2. Unscrew the valve cover bolts using a socket set, keeping them organized.
3. Carefully lift off the valve cover and remove the old gasket.
4. Clean the mating surfaces with a gasket scraper and brake cleaner.
5. Place the new gasket on the valve cover, then reattach the cover and torque the bolts to manufacturer specifications (typically around 7-9 ft-lbs).

4. Replace Front Crankshaft Seal (if leaking)

Sub-steps:
1. Remove the drive belts and any pulleys blocking access to the crankshaft seal.
2. Use a puller to remove the crankshaft pulley.
3. Carefully pry out the old crankshaft seal using a seal puller.
4. Lubricate the new seal with engine oil and install it carefully to avoid damage.
5. Reattach the crankshaft pulley and torque to specifications (usually around 50-70 ft-lbs).

5. Refill Engine Oil

After completing the repairs, refill the engine oil to the proper level using the specified oil type (typically 5W-20 or 0W-20).
