After repair or replacement of valve train components, it becomes necessary to adjust the valve clearances. This is clearly evidenced by the increased noise emanating from the valve train, detected when listening to the engine.
It is necessary
- - stylus of 2 class of accuracy
- - spanners
- - set of heads
Instructions
Step 1
When adjusting the valves, make sure that there is no dirt or dust under the hood that could get under the valve cover. Begin the adjustment procedure after four hours of inactivity of the machine so that the motor is cooled below 38 degrees.
Step 2
Jack up the vehicle and remove the front wheel on the passenger side. Remove the engine cover over the intake manifold, secured with two chrome bolts. Then - the spark plug cover bolted on the studs.
Step 3
Disconnect the crankcase ventilation pipe or remove the box with the air filter. Having disconnected the chips from the wiring, remove all four coils, each of which is fastened with a pair of bolts. Unscrew six nuts from the valve cover, remove the oil dipstick.
Step 4
If the valve cover does not come off, making sure that the accelerator cable or pipes are not holding it, pry it slightly. After removing the cover, wrap it in plastic wrap. Using a long universal joint and a 19 knob, turn the crankshaft to the "VTC" mark on the gear, which should be pointing up. The notches on the teeth of both gears should point towards each other. In this position, the first cylinder on the passenger side reaches top dead center.
Step 5
Begin adjusting from the inlet valve. Insert the dipstick blade into the gap between the rocker arm and the end of the valve stem, or between the valve arm and the cam of the intake camshaft. Pay attention to the advancement of the stylus, which should slide in the gap with little resistance.
Step 6
If necessary, loosen the lock nut with a spanner wrench, loosen the adjusting screw with a screwdriver. Then, to achieve the desired effect on the stylus blade, start tightening the adjusting screw. Use a screwdriver to secure it from turning and tighten the lock nut. After making sure that the clearance has not changed while tightening the nut, in the same way adjust the clearances of the second inlet and two exhaust valves in turn.
Step 7
Rotate the crankshaft 180 degrees counterclockwise. In this case, the camshaft pulley should rotate 90 degrees. Bring the piston of the third cylinder to the position of the top dead center of the end of the compression stroke. Pay attention to the UP mark on the camshaft gears. She should take the 9 o'clock position. Check and adjust the valves of the third cylinder.
Step 8
Crank the crankshaft another 180 degrees counterclockwise to adjust the valves on the fourth cylinder. Turn the crankshaft 180 degrees again (the UP mark will move to the 3 o'clock position) and repeat the procedure for the valves of the second cylinder.
