The oil pan gasket sits below the engine block in the area called the crankcase, named so because that is where the crankshaft resides. It is compressed between the crankcase and a durable steel pan or cast pan. The pan is relatively thinner than the crankcase, which is generally cast from iron, aluminum or alloy.

Signs of a Failing Oil Pan Gasket If you find yourself topping off your engine oil more frequently than usual, it could be due to a leaky gasket. When oil drips from the gasket onto hot engine parts, it can produce a noticeable burning oil smell.

One only change the oil pan gasket when the oil pan is damaged and leaking oil because some object hit it while driving. The only thing you might change may be the drain plug washer because it was missing or damaged by over tightening of the the drain plug.

The average cost for an Oil Pan Gasket Replacement is between $425 and $509. Labor costs are estimated between $305 and $385 while parts are priced between $119 and $123. This range does not include taxes and fees, and does not factor in your unique location. Related repairs may also be needed.
