Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and allow the engine to cool.
Disconnect the battery to ensure safety.

2. Inspect and Replace the Oil Filter

Tools Required: Oil filter wrench, drain pan
Remove the oil filter using the oil filter wrench. Ensure the drain pan is placed underneath to catch any residual oil.
Inspect the old oil filter's rubber O-ring for damage and ensure it was removed with the filter.
Install a new oil filter, lubricating the O-ring with a small amount of fresh oil.

3. Replace the Oil Pan Gasket (if leaking)

Tools Required: Socket set, torque wrench, gasket scraper
Drain the engine oil completely into the drain pan.
Remove the bolts securing the oil pan using the socket set.
Carefully pry the oil pan away from the engine block and remove the old gasket material using the gasket scraper.
Clean the surface of the oil pan and engine block thoroughly.
Apply a new gasket or gasket maker as per the manufacturer's specifications.
Reinstall the oil pan and torque the bolts to the specified torque setting (typically around 10-15 ft-lbs, consult the service manual for exact specifications).

4. Inspect and Replace Seals (if necessary)

Tools Required: Socket set, seal puller
Inspect the front crankshaft seal and camshaft seals for leaks.
If seals are leaking, remove the necessary components (such as the timing cover or accessory belts) to access the seals.
Use the seal puller to carefully remove the old seals and install the new ones. Ensure they are seated properly.

5. Refill Engine Oil

Tools Required: Funnel
Refill the engine with the appropriate type and amount of oil as specified in the owner's manual.
Start the engine and let it run for a few minutes, checking for leaks.
