How to adjust the valve of automobile hydraulic tappet.

First of all, the general principle is that the valve clearance can only be adjusted when the valve is completely closed. When the convex part of the cam does not press the rocker arm (valve stem tail), the valve clearance of this valve can be adjusted.

Second, the valve clearance of this valve can be adjusted when the circular part of the cam contacts the rocker arm (the tail of the valve stem).

3. When the idle motor, throttle position sensor and other parts are in good condition, first loosen the limit bolt and manually open the throttle, so that the hand will feel a little stuck. Then, adjust the adjusting bolt inward and push the throttle slightly to make the throttle slightly open, that is, as long as the hand feels that there is no hairpin, because hairpin will accelerate the damage of the engine valve several times.
