Remove the cylinder head and the cylinder head gasket (Fig. 6.43). Using alcohol, clean the sealing surfaces of the head and cylinder block from gasket residue.
The thickness of the gasket is determined by the number of marking holes (from 1 to 3). Using compressed air (2.0 bar), clean all blind threaded holes from dirt due to the risk of cracks. Use a cylinder head gasket with the same marking (1, Fig. 6.44), by the number of holes.
Attention! If the work performed may cause a change in the amount of piston crown protrusion, it is necessary to re-determine the thickness of the cylinder head gasket.
During installation, the joints of the timing cover and the cylinder block are sealed using serially glued sealing strips (arrows). It is not necessary to apply sealant in these places. Assemble the engine.
