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 to prevent any electrical issues while working.

2. Identify and Replace Leaking Gasket/Seal

Tools Required: Socket set, torque wrench, gasket scraper, engine oil, new gaskets/seals.
Locate the source of the oil leak (e.g., valve cover gasket, oil pan gasket).
Remove any components obstructing access to the gasket or seal (e.g., air intake, engine covers).
Unbolt the valve cover or oil pan using the socket set.
Carefully scrape off the old gasket material from the mating surfaces using a gasket scraper.
Clean the surfaces thoroughly with a degreaser and allow them to dry.
Apply a thin layer of gasket sealant if required, then place the new gasket in position.
Reinstall the valve cover or oil pan and torque the bolts to the manufacturer’s specifications.

3. Replace Oil Filter

Tools Required: Oil filter wrench, oil catch pan.
Use an oil filter wrench to remove the old oil filter.
Apply a small amount of new engine oil to the rubber seal of the new filter.
Install the new oil filter by hand until snug, then give it an additional 3/4 turn.
Ensure the filter is properly tightened to prevent leaks.

4. Refill Engine Oil

Tools Required: Funnel, clean rag.
After replacing any gaskets, refill the engine with fresh oil using a funnel.
Check the owner’s manual for the correct oil type and capacity.
Start the engine and let it run for a few minutes, then check for any leaks.
