If the oil pan gasket is leaking, the engine oil pan will often need to be resealed. There might also be internal seals in the oil pan that seal oil passages for the oil pump—if these leak, the oil pan will need to be resealed.
The oil pan is sealed with a gasket, which can be made of paper, rubber, or a sealing liquid (liquid gasket).
How to Reseal the Oil Pan
- Drain engine oil
- Remove oil filter
- Remove oil pan
- Clean off old gaskets or sealing material and the oil pump pick-up screen
- Install new gaskets, seals, or sealing liquid
- Install oil pan
- Add engine oil and replace oil filter
