Check for leaks and damage

To check for leaks and damage, look underneath your car to see if there is a pool of oil or a greasy oil pan and exhaust system. You may also notice low oil levels, smoke, or a burning smell coming from the engine compartment. If you see any of these signs, schedule an inspection immediately.

When checking for leaks, it's important to verify that the gasket is leaking directly from the oil pan and not just collecting oil from a different leak. Leaking oil can also be caused by issues with the drain plug, oil filter, or other components above the pan.
