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 (if working on electrical components).

2. Inspect and Replace Oil Filter

Sub-steps:
1. Locate the oil filter (usually near the oil pan).
2. Use an oil filter wrench to remove the old oil filter.
3. Apply a small amount of new oil to the rubber gasket of the new filter.
4. Install the new oil filter hand-tight, ensuring a proper seal.

3. Inspect and Replace Gaskets

Sub-steps:
1. If the oil filter is not the source, proceed to remove the engine cover (if applicable).
2. Examine the valve cover gasket; if leaking, remove the valve cover bolts and lift the cover.
3. Clean the mating surfaces and replace the gasket with a new one.
4. Reinstall the valve cover and torque bolts to manufacturer specifications.

4. Oil Pan Inspection and Replacement

Sub-steps:
1. If the oil pan gasket is leaking, drain the engine oil completely.
2. Remove the oil pan bolts and gently pry off the oil pan.
3. Clean the oil pan and engine block surfaces.
4. Install a new oil pan gasket and reattach the oil pan with the correct torque settings.

5. Replace Seals (if necessary)

Sub-steps:
1. Inspect the front and rear main seals using a flashlight.
2. If worn, remove the crankshaft pulley (front) or flywheel (rear) to access the seals.
3. Replace the seals and reassemble the components, ensuring correct torque specifications.
