Oil Pan Gasket

What it does
The oil pan is the metal bowl bolted to the very bottom of the engine that holds your engine oil when the engine is not running. A gasket (or on some engines, an RTV silicone bead) seals the edge where the pan meets the engine block. When that seal fails, oil slowly drips from the bottom of the engine — usually leaving a dark oval-shaped puddle centered under the front of your car. Unlike the valve cover gasket (on top), the oil pan gasket is on the underside, so you usually need to raise the car to see it.

Frequently asked questions
How serious is an oil pan gasket leak?
Moderate urgency. Unlike a coolant leak (which can overheat the engine within miles), an oil pan gasket leak usually drips slowly. But check your oil level weekly — running even a quart low significantly increases wear on bearings and the cylinder walls.
Why does oil pan gasket replacement cost so much if the part is cheap?
The gasket itself is $10–$25. But replacing it requires raising the car on a lift, draining the oil, unbolting and lowering the oil pan (which may require moving exhaust components, a crossmember, or other parts on some vehicles), cleaning both surfaces meticulously, and reassembling. It's a 2–4 hour job at the shop.
Can I use a sealant instead of a new gasket?
On some engines, the manufacturer uses only RTV silicone (no gasket) — and replacing with the same high-temp RTV is the correct repair. Other engines use a formed rubber or composite gasket. Use the appropriate repair for your application — check the factory service manual or ask a parts store for the correct product.
