Abstract
A sealing system is associated with an engine having two engine parts to be sealed, and includes a gasket situated between the engine parts. The engine parts include at least one annular groove around a hole to be sealed, and the gasket includes a bead extending outwardly from the gasket around the hole. The size o the bead is greater than that of the annular groove. When the gasket is tightened between the engine parts, the bead is compressed inside the groove and deforms to securely seal between the gasket and the engine parts. As a result, even if the engine part is slightly moved, the gasket can securely seal between the engine parts.
