Checking and adjusting clearances in the valve drive mechanism
Checking and adjusting the clearances in the valve drive mechanism should be carried out when the oil temperature is about 80°C.
Shine the cylinder head cover, being careful not to damage the gasket.
Engage IV or V gear and, moving the car, turn the crankshaft so that the intake and exhaust cams of the adjustable cylinder are facing up in the same position.
Warning. It is forbidden to turn the crankshaft by the camshaft pulley bolt, so as not to damage the toothed frame.
In this position, check the gaps with a flat feeler gauge between the lever and the back of the camshaft cam. To adjust the gap, turn the self-locking adjusting bolt with a ball head with a key to set the required gap on the probe.
Turning each time the crankshaft to the position for adjusting the thermal clearances of the valves, adjust the clearances of the remaining valves.
Clearances in the valve drive mechanism
Normal clearance between the lever and the back of the camshaft cam, measured with a feeler gauge, on a cold engine (after repair) is 0.10 mm for intake valves and 0.20 mm for exhaust valves, on a hot engine - 0.15 and 0.25 mm, respectively.
