Over time, the heat and vibration of the engine cause this rubber or cork-based gasket to harden and crack. The path your engine oil takes from the reservoir to the farthest components creates multiple potential exit points.
Why Is My Car Leaking Oil From Engine: Common Causes and Solutions
Internal Engine Factors Sometimes, the leak is not due to a simple external seal but rather the result of internal pressure forcing oil out through the weakest available path. This scenario is often more complex and requires a closer look at how the engine breathes and how the oil behaves under extreme conditions.
This excessive force will eventually force oil past any weak seal, such as the valve cover gasket or dipstick tube, creating a leak. Pressure from Blow-By Combustion events are meant to stay contained within the combustion chamber, but microscopic amounts of gas—known as blow-by—can slip past the piston rings.

The oil filter presents a similar risk; if the gasket on the new filter is not lightly coated with fresh oil before tightening, or if the filter is not secured hand-tight plus a quarter turn, it can begin seeping immediately. Understanding why this happens requires looking at the stress oil endures, the materials involved, and the specific components that can fail over time.
