I have driven a five-valve golf cart1.2000 km. After washing the accelerator and dripping, the fuel consumption actually increased, reaching more than 100 kilometers 1.3 liters, and I also burned some engine oil. Hello, it usually takes three packs for vehicles to burn engine oil, but there are really not many golf courses with three packs after 654.38+0.2 million kilometers, but there are many reasons for burning engine oil. In addition to the aging of the oil ring, the oil leakage of the valve oil seal will also burn the oil. You can try it, whether it's blue smoke when the car is cold in the morning or blue smoke all the time. If it is not taken after the hot car, it can be determined that the valve oil seal is aging, and the oil seal can be replaced. That's three bags. Golf five-valve engine is the same as the new Jetta (sagitar 1.6 Bora 1.6), a pair of rings1about 80 yuan (the auxiliary factory guarantees100000 km), and there are matching replacement cylinder pads, valve oil seals and large and small tiles. If you buy spare parts yourself, you will pay the working hours of the repair shop, which is about 100 yuan-150 yuan. Your spare parts need 300 yuan. If the valve doesn't leak, it depends on whether it needs to be replaced. If it needs to be replaced, I have included the cost of grinding the valve in this 300 yuan. The gas money is not counted. FAW-Volkswagen is in the factory.
