Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the engine is cool before beginning work.
Disconnect the battery to prevent any electrical issues.

2. Inspect and Tighten Oil Filter/Drain Plug

Use an oil filter wrench to tighten the oil filter if loose.
Using a socket set, check the torque of the oil drain plug; it should be tightened to the specified torque (usually around 25-30 ft-lbs, but check the manual for specific values).

3. Replace Oil Filter and Drain Plug (if damaged)

Oil Filter Replacement:
- Place a drain pan under the oil filter.
- Remove the old filter, allowing any excess oil to drain into the pan.
- Apply a bit of fresh oil to the rubber gasket of the new filter.
- Install the new filter and tighten it by hand until snug.
Drain Plug Replacement:
- If the drain plug is stripped or damaged, replace it with a new one.
- Clean the area around the oil pan where the drain plug seats.
- Install the new drain plug and tighten to the specified torque.

4. Replace Valve Cover Gaskets (if leaking)

Remove any components obstructing access to the valve cover (e.g., air intake, ignition coils).
Unscrew and remove the valve cover.
Scrape off the old gasket material from the valve cover and engine surface.
Place the new gasket on the valve cover, ensuring it is seated properly.
Reinstall the valve cover and tighten the bolts to the specified torque.

5. Replace Front/Rear Main Seals (if necessary)

For the front main seal, remove the crankshaft pulley and any timing belt components as needed.
Remove the old seal using a seal puller.
Apply a small amount of engine oil to the new seal’s lip and install it correctly.
For the rear main seal, this usually requires removing the transmission. Follow the manufacturer's service manual for precise removal and installation steps.
