Oil leaks occur for a number of reasons, and may be fixed through various methods.
For a 2006 Toyota Avalon, engine repairs were needed.
When the car was previously brought in for general service, we noticed oil leaks and recommended a new engine oil pan gasket and engine timing cover gasket. The customer also noticed small drops of oil under the vehicle.

Oil leaks and oil changes
A bad oil filter, broken filler cap, and insecure drain plug are other issues that could lead to oil leaks.
Regular maintenance, such as oil changes, can prevent engine wear and keeps the internal system clean by preventing sludge build up. This can keep passages open and PCV Positive crankcase ventilation (PCV) systems clear.
If the PCV systems become clogged, they can put increased crankcase pressure on the engine which could produce oil leaks.
We recommend oil changes every 3,000 to 5,000 miles. To learn more about when and why to get an oil change, read this article we published.
