Remove the tappets with adjusting washers. The tappets should be stored in such a way that during assembly they end up in the same places from which they were removed during disassembly.
Compress the valve springs with special pliers so that you can remove the lock crackers. Remove the remaining parts related to the valve subassemblies from the cylinder head.
Remove the vacuum pump drive pusher.
Remove the two engine lifting hooks located on the cylinder head.
Remove the oil pressure sensor and disconnect the cooling system hoses.
Remove the valve stem seals and take out the valve spring retainers.
The parts related to the cylinder head assembly are shown in Fig. 2.73.
Checking and repairing the cylinder head is carried out in exactly the same way as was previously described in the subsection devoted to checking and repairing the cylinder head of a 1.4i/1.6i petrol engine.
The prechamber can protrude above the cylinder head seating surface by up to 0.06 mm.
The cylinder head is assembled in the reverse order. The clearances of the intake valves are 0.30 mm. The exhaust valves are 0.50 mm. The corresponding washers (linings) are included in the spare parts kits. To adjust the valve clearance, the cam is installed vertically above the tappet.
The clearance is measured with a feeler gauge and the results are recorded. Turn the camshaft 1/8 of a turn and use tool 21-106 to push the tappet down. With this setup, the tappet adjusting washer can be replaced. The adjusting washers have markings located underneath (on the surface adjacent to the tappet). To replace, use new washers, placing them on dry tappets.
Note: The cylinder head seating surface (in contact with the cylinder head gasket) cannot be machined.
