If leaks are found at the front crankshaft or camshaft seals, remove the components necessary to access these areas.
Using a gasket scraper, remove old gasket material and clean the surfaces.
Install new seals or gaskets according to the manufacturer’s specifications.

5. Refill Engine Oil

Fill the engine with new oil through the oil filler cap, using the recommended oil type and quantity as per the owner’s manual.
Start the engine and let it idle for a few minutes while checking for leaks.
