Distinctive features of installation of cylinder head gasket of diesel engine (Audi 100 C4)

When replacing the cylinder head gasket, it is necessary to pay attention to its marking and replace it only with a gasket with the same marking.

Cylinder head gaskets have different thicknesses. Depending on this, one or three holes are punched on the gasket (or cutout).

Please note: The gasket marking is visible even when the cylinder head is not removed.

When installing new pistons or other engine parts, piston protrusion must be measured and shim thickness must be properly selected.

If the gasket is installed without using a sealant, it must be positioned so that it does not block the holes, and the inscription "TOP" must face the cylinder head.
