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 avoid electrical issues during repairs.

2. Identify and Repair the Leak Source

A. Valve Cover Gasket Replacement

Remove engine cover (if applicable) using a socket set.
Unbolt the valve cover using the appropriate socket.
Carefully lift off the valve cover and inspect the gasket for damage.
Clean the mating surfaces on the cylinder head and valve cover.
Install a new valve cover gasket, ensuring proper alignment.
Reinstall the valve cover and torque the bolts to the manufacturer's specifications.

B. Oil Pan Gasket Replacement

Drain the engine oil using an oil catch pan.
Remove the oil pan bolts and gently tap the pan to break the seal.
Remove the old gasket material from the oil pan and engine block.
Apply a new gasket or RTV sealant as per manufacturer specifications.
Reinstall the oil pan, ensuring even torque on all bolts.
Refill the engine with the appropriate type and amount of oil.

C. Oil Filter Replacement

Locate the oil filter and use an oil filter wrench to remove it.
Lubricate the rubber O-ring on the new oil filter with fresh oil.
Install the new oil filter by hand, ensuring it is snug but not overtightened.
Check the oil filter mounting surface for leaks after installation.
