How much is it to change the valve oil seal? Even working hours?

The cost of replacing the valve and oil seal of a car plus the working hours will not be less than 1500 yuan. I suggest you choose a good shop. As long as it is not a luxury sports car like BMW Benz, 1500 to 2000 can be considered for replacement.

Valve oil seal can prevent engine oil from entering the intake and exhaust pipes, avoid engine oil loss, prevent the mixture of gasoline and air and waste gas from leaking, and prevent engine oil from entering the combustion chamber.

Matters needing attention in the use of valve oil seal

Pay attention to centering when replacing the valve oil seal. Before installing in the exhaust pipe, the rod must be coated with a layer of engine oil to avoid a series of sequelae. When installing the valve oil seal, you must use special tools to check whether the lip is deformed and whether the lip is everted. If the lip is deformed or everted, it must be reinstalled, otherwise it will easily lead to insufficient tightness, which will cause the guide rod to continue to leak oil. It is best not to replace the valve oil seal.

Attention should be paid to the quality of the valve oil seal, which is directly related to the oil leakage of the automobile. If the valve oil seal is damaged, the car will start burning oil, blue smoke will appear when the car is cold started, and the engine will accelerate and vibrate, so it should be replaced in time.
