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 for safety.

2. Oil Filter Replacement

Use an oil filter wrench to remove the old oil filter.
Apply a light coat of new oil to the rubber gasket of the new filter.
Install the new oil filter by hand until snug, then tighten according to the manufacturer's specifications (usually 3/4 turn after it contacts the base).

3. Replace Gaskets and Seals

A. Oil Pan Gasket Replacement

Drain the engine oil using a wrench to remove the drain plug.
Remove the oil pan bolts using a socket set.
Carefully remove the oil pan and clean the mating surfaces with a scraper.
Install a new oil pan gasket and reattach the oil pan with the correct torque specifications.
Reinstall the drain plug and fill the engine with new oil.

B. Valve Cover Gasket Replacement

Remove any components obstructing access to the valve cover.
Unscrew the valve cover bolts and carefully lift off the valve cover.
Clean the gasket surfaces on both the cover and cylinder head.
Install the new valve cover gasket and reassemble the valve cover, tightening the bolts to the manufacturer’s specs.

4. Final Check

Reconnect the battery.
Start the engine and let it run for a few minutes while checking for leaks.
Recheck the oil level and add oil if necessary.
