How to judge whether the valve oil seal leaks oil? Introduction of judgment method

Cars, like people, sometimes have some problems. These are very common. Do you know how to judge whether the valve oil seal leaks oil? Next, let me introduce you. Determine whether the valve oil seal leaks oil: measure the cylinder pressure. If it is a piston ring problem, judge the wear amount by the cylinder pressure data. If it is not too serious, or it is a cylinder problem, it should be repaired automatically by adding a repairing agent after driving 1500 km. Judge whether the valve oil seal leaks oil: look for blue smoke at the exhaust port. Blue smoke is a phenomenon of burning oil, which is mainly caused by the wear of piston, piston ring, cylinder liner, valve oil seal and valve guide. But first of all, it is necessary to eliminate the phenomenon of oil burning in the exhaust pipe, that is, the oil-water separator and PVC valve will burn oil if they are damaged. To judge whether the valve oil seal leaks oil, we can use the method of refueling the valve and releasing the throttle. The blue smoke from the exhaust pipe of the filling valve is caused by the excessive wear clearance of the piston, piston ring and cylinder liner. The blue smoke from the exhaust pipe of the throttle release device is the damage of the valve oil seal and the wear of the valve guide. In fact, as long as it is used, people and things will fail to varying degrees. Mainly depends on how we solve it. Is everyone clear about what I introduced to you today? Let's call it a day.
