How to adjust the valve of Elantra engine?

Adjustment method of multi-cylinder machine: \x0d\ 1. Crankshaft pulley is equipped with scale 0 and timing gear pointer. \x0d\2。 If you only look at the rocker arm, that is, when the top dead center of 1 cylinder is compressed, the exhaust valve of cylinder 4 has not been closed, and the intake valve has just opened (that is, the valves overlap). That is to say, when the intake valve of cylinder 4 has just opened, it is the top dead center. \x0d\3。 The most stupid way is to remove the high-pressure oil pipe, and the compression top dead center is the one that finishes spraying oil. \x0d\4。 Adjust the near exhaust valve of 1 cylinder, and the intake valve of cylinder 2 and exhaust valve of cylinder 3 at the top dead center of 1 cylinder. Turn the crankshaft for another 360, and adjust the intake and exhaust valves of cylinders 4, 3 and 2 \x0d\5. If it is cylinder by cylinder adjustment, find the compression top dead center of 1 cylinder, adjust 1 cylinder, then turn the crankshaft 180, adjust the intake valve and exhaust valve of cylinder 3, and then turn the crankshaft 180. Then turn 180 to adjust the intake valve and exhaust valve of cylinder 2.
