If you can't solve an oil leak by replacing the oil pan gasket, you might have to consider replacing the entire oil pan. It could be that a large puncture has punched a hole through the oil pan, or if the surface has been eaten away by rust. In this instance, only a complete replacement will suffice. In general, an oil pan replacement will cost you around $300 to $800. It'll vary wildly depending on the make and model of your vehicle, though. Luxury vehicles, for example, might set you back $1,000 or more just to replace the oil pan. The parts themselves aren't too expensive, with an oil pan costing around $150 to $500. The rest of the expenses - about $150 to $400, on average - are all dedicated to labor costs.
