As of 2015, the average cost to repair an oil pan gasket ranges from about $400 to $500. The specific price is dependent upon the driver's location, as well as the make and model of her car.
The cost of repairing an oil pan gasket varies drastically depending on whether the driver repairs the car herself or takes the car to a professional mechanic. The part itself averages between $15 and $30, while labor typically costs between $380 and $480. However, because the oil pan is at the bottom of the vehicle, an oil pan leak may actually reveal other parts in need of repair, which would increase the overall cost.
