Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and secure it with wheel chocks.
Disconnect the battery to prevent electrical issues.

2. Oil Filter Replacement

Tools Required: Oil filter wrench, drain pan, new oil filter
Remove the old oil filter using the oil filter wrench.
Allow any remaining oil to drain into the drain pan.
Lubricate the rubber gasket on the new oil filter with a small amount of oil.
Install the new oil filter, tightening it by hand until snug.

3. Replace Gaskets (if necessary)

Tools Required: Socket set, torque wrench, gasket scraper
If the valve cover or oil pan gaskets are damaged, remove the corresponding components:
- For the oil pan, drain the engine oil completely.
- Remove the bolts securing the oil pan and carefully detach it.
- Clean the mating surface using a gasket scraper to remove old gasket material.
- Install a new gasket and reattach the oil pan, torqueing to manufacturer specifications (usually around 10-12 Nm).
For the valve cover:
- Remove the bolts securing the valve cover.
- Clean the surface and replace the gasket.
- Reinstall the valve cover and torque to specifications (typically 8-10 Nm).

4. Refill Engine Oil

Tools Required: Funnel, new engine oil
Once all repairs are completed, refill the engine with the correct type and amount of oil as specified in the owner’s manual.

5. Final Checks

Reconnect the battery.
Start the engine and allow it to run for a few minutes while checking for leaks around the replaced components.
Check the oil level again and top off if necessary.
