Anatomy of a Drain Plug and the Sealing Mechanism The oil drain plug is a critical component, typically a large bolt located at the lowest point of the oil pan. Forgetting to replace a crushed or damaged washer, or incorrectly tightening the plug to either an insufficient torque—leading to a loose fit—or excessive torque—causing the aluminum washer to deform or the plastic housing of the oil pan to crack—can initiate a leak.
