Make sure that the blind holes in the cylinder block are clean, paying particular attention to the absence of traces of oil on their bottom, since the compression of oil when tightening the cylinder head bolts can lead to cracks in the cylinder block.
Apply Curil K2 type sealant to the mating surface of the timing cover.
Install the cylinder head gasket.
Position the camshaft so that the hole in its flange is facing down and the groove in the flange is aligned with the boss on the cylinder head.
In this case, the piston of the 1st cylinder should be at TDC at the end of the compression stroke, and the mark on the rim of the crankshaft pulley should be opposite the pointer on the lower cover of the valve timing mechanism.
Install the cylinder head and tighten gradually in four stages in the order shown (for bolt tightening torques, see subsection "Detailed technical specifications").
Place the camshaft toothed pulley on the flange flange, aligning the pulley mounting bolt holes on the pulley and flange. Tighten the camshaft pulley mounting bolts and lock them by bending the locking plates.
Install the plunger, spring and plug of the camshaft drive chain tensioner; in this case, the plunger must enter the tensioner body until it stops.
Adjust the valve clearances.
Install the fuel pump, central oil line and ignition distributor.
Further installation of the cylinder head is carried out in the reverse order of removal.
