How to adjust the valve in Southeast Delica? Specific method

The loud valve proves that your Delica is a Dongfeng engine, but it needs to be said that the valve is not easy to adjust, especially your engine. There are many reasons why the valve of Dongfeng engine is unclear. There is an oil pipe on the cylinder head of this machine. If it's blocked, it's no use tuning it to death. Necessary tools, pliers, cross flat screwdriver, ten small sleeves with connecting rods and flying wrenches (necessary), a wrench of 19 years, a wrench of 15 years, an adjusting feeler and sealant. When you open the passenger seat, you will see that two clamps are removed from the intake pipe, four long screws are removed from the throttle body, and four short screws are removed from the idle valve body. Do not unplug the plug, and start to remove the valve cover. Probably a screw with a washer. This way, you can see the valve. How to adjust it specifically? In the most primitive way, one cylinder at a time. First, adjust a cylinder. After adjusting the exhaust valves of cylinders 4 and 4, the valve of 1 cylinder can be adjusted without knowing that the intake valve is starting to suck down. Nineteen wrenches are used to loosen the cover and fifteen wrenches are used to tighten the adjusting screws. After adjustment, turn the crankshaft pulley, observe that cylinder 3 adjusts cylinder 2 when it reaches the top dead center, and then turn to 1 cylinder. Look at adjustment 4, then go to top dead center of cylinder 2 or cylinder 3 to look at adjustment 3, and the adjustment is over. Once you know it, you can adjust it yourself. If you don't understand, ask a mechanic to adjust it. Note: if you want to keep the valve silent, you have to adjust it in this stupid way, otherwise it will be useless. I don't care about other cars, this car is like this. PS: Pure hand tour, please.
