A 3-layer metal-layer cylinder head gasket is used.
The 2 spring steel layers (function layers) of the cylinder head gasket are made from a spring band. The stopper is impressed onto the intermediate layer (spacer layer). The spring steel layers are made from stainless steel. Additional partial coatings optimize the function of the cylinder head gasket.
Metal-layer gaskets made of multi-layer sheet steel inserts are used in engines which are subjected to high loads. The primary characteristic of the metal-layer gasket is that the seal is determined by the integrated bead and stopper layers in the sheet steel inserts.
The deformation properties of the metallic cylinder head gasket enable the gasket to adapt optimally to the components in the cylinder head area while providing for a high degree of elastic recovery to compensate for component deformation. Such elastic recovery arises in response to thermal and mechanical loads.
The cylinder head gasket comes in 3 different thicknesses, depending on the respective piston protrusion. The thickness is identified in the cylinder head gasket by holes, where one hole signifies the thinnest and three holes signify the thickest.
| Bore Holes | 1 | 2 | 3 |
| Gasket Thickness | 0.95 mm (0.0374 in.) | 1.05 mm (0.0413 in.) | 1.15 mm (0.0453 in.) |
