Solution

1. Preparation

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

2. Locate and Replace Oil Filter

Tools Required: Oil filter wrench, drain pan, rags.
Remove the old oil filter using the oil filter wrench. Allow any remaining oil to drain into the pan.
Apply a thin layer of new engine oil on the rubber gasket of the new oil filter.
Install the new oil filter, tightening it by hand until snug, then tighten an additional 3/4 turn.

3. Replace Oil Drain Plug

Tools Required: Socket set, torque wrench, drain pan.
Place the drain pan under the oil pan and remove the oil drain plug with the socket set.
Inspect the old drain plug and replace it if damaged or worn.
Reinstall the drain plug and tighten it to the manufacturer’s specified torque (usually around 20-25 ft-lbs).

4. Replace Gaskets as Necessary

Tools Required: Gasket scraper, sealant, torque wrench.
If the valve cover or oil pan gaskets are leaking, remove the respective component.
Clean the gasket surfaces thoroughly using a gasket scraper.
Apply a suitable gasket sealant as required and install the new gasket.
Reinstall the valve cover or oil pan and tighten bolts to the manufacturer’s specified torque.

5. Refill Oil

Tools Required: Funnel.
Remove the oil filler cap and use a funnel to add new engine oil to the engine.
Check the oil level with the dipstick and adjust as necessary.
