Solution

1. Preparation

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

2. Remove Oil Filter

Tools Required: Oil filter wrench, drain pan.
Place the drain pan under the oil filter.
Use the oil filter wrench to remove the oil filter, allowing any remaining oil to drain into the pan.
Inspect the old oil filter’s rubber O-ring to ensure it came off with the filter.

3. Inspect and Replace Gaskets

Tools Required: Socket set, torque wrench, gasket scraper, clean rags.
For the oil pan gasket:
- Remove the oil pan bolts with the socket set.
- Carefully remove the old gasket using a gasket scraper.
- Clean the mating surfaces thoroughly.
- Install a new gasket and reattach the oil pan, torquing the bolts to the manufacturer's specifications.
For the valve cover gasket:
- Remove the valve cover bolts and lift the cover.
- Replace the old gasket and ensure the new gasket fits properly.
- Reinstall the valve cover and torque the bolts as specified.

4. Check and Replace Seals

Tools Required: Seal puller, appropriate socket set.
Inspect the front and rear main seals. If they are leaking, remove the crankshaft pulley (front) or the transmission (rear) to access the seals.
Replace the seals with new ones, ensuring they are seated correctly.

5. Reinstall Oil Filter and Fill Oil

Install a new oil filter, ensuring the rubber O-ring is lubricated and seated properly.
Fill the engine with the correct type and amount of oil as specified in the owner’s manual.
