Solution

1. Preparation

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

2. Identify and Fix the Leak Source

A. Oil Filter Replacement (if leaking)

Place an oil catch pan under the oil filter.
Use an oil filter wrench to remove the old oil filter.
Apply a thin layer of fresh oil to the rubber gasket of the new oil filter.
Install the new oil filter by hand until snug, then tighten an additional 3/4 turn.

B. Replace Valve Cover Gasket (if leaking)

Remove any components obstructing access to the valve cover (e.g., air intake hose).
Unbolt the valve cover using a socket set, being careful not to damage any surrounding components.
Remove the old gasket and clean the valve cover and cylinder head surfaces with a gasket scraper.
Install a new valve cover gasket, ensuring it is seated properly.
Reinstall the valve cover and torque the bolts to the manufacturer’s specification (typically around 7-9 lb-ft).

C. Repair Oil Pan (if leaking)

Drain the engine oil using a drain pan and remove the drain plug.
Remove the oil pan by unbolting it from the engine block, being cautious of any remaining oil.
Clean the oil pan and the mating surface on the engine block with a scraper.
Apply a new gasket or sealant as per manufacturer specifications.
Reinstall the oil pan and torque the bolts to the specified value (usually around 12-15 lb-ft).
Reinstall the drain plug and refill the engine with the appropriate oil type.

3. Reconnect Battery

Reconnect the battery terminals ensuring they are tight.
