Solution

1. Preparation

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

2. Identify Leak Source

Clean the engine area with a degreaser to remove old oil and debris.
Use a flashlight to inspect the cleaned areas for fresh oil leaks.
Mark the leak source with a marker for reference.

3. Repair the Leak

A. Valve Cover Gasket Replacement

Remove the valve cover bolts using a socket set.
Lift off the valve cover carefully to avoid damaging the gasket.
Clean the mating surfaces on both the engine and the valve cover.
Install a new gasket onto the valve cover.
Reinstall the valve cover and tighten the bolts to manufacturer specifications (usually around 10-15 ft-lbs).

B. Oil Pan Gasket Replacement

Drain the oil from the oil pan by removing the drain plug.
Remove the oil pan bolts using a socket set and carefully pry the pan away from the engine.
Clean the oil pan and engine block surfaces thoroughly.
Apply a new gasket or RTV sealant as per manufacturer specifications.
Reinstall the oil pan and torque the bolts to specification (around 10-15 ft-lbs).
Reinstall the drain plug securely.

C. Oil Filter and Drain Plug Check

Inspect and replace the oil filter if it is leaking. Use an oil filter wrench to remove it.
Apply a small amount of oil to the rubber gasket of the new filter before installing.
Tighten the oil filter securely, but do not overtighten.
Ensure the drain plug is tight and not cross-threaded.

4. Refill Engine Oil

Refill the engine with the correct type and amount of oil (typically 5W-30 or as specified in the owner's manual).
Start the engine and let it idle for a few minutes to circulate the oil.
