What causes oil leakage in CFMoto 250SR?
2 Answers
Excessive transmission fluid. Below are detailed explanations: 1. Excessive transmission fluid: There are clear oil stains on the surface of the car engine's housing. If these stains are cleaned and soon reappear, or in severe cases, oil drips like water droplets, the car should be sent for repair as soon as possible. 2. Solution: Replace all sealing rings. Urban traffic congestion requires constant gear shifting; modern cars have more gears, leading to increased shifting frequency, greater working pressure and higher temperatures inside the transmission, which accelerates the aging and deformation of rubber seals at the transmission's sealing points.
I have extensive experience in car repairs. Oil leaks on the CFMoto 250SR are quite common, mostly caused by aging seals or improper installation. Common leak points include the oil pan, filter interface, or around the crankcase cover. After a few years, oil seals may crack, leading to oil seepage; loose bolts can also cause leaks. You can start by checking yourself: run the engine until it's warm, observe where the oil stains seep from, and try tightening the bolts by hand if it's simple. However, if the leak is severe, not addressing it promptly could lead to engine damage, which is more troublesome. So, I recommend not delaying—either buy the parts and replace them yourself (there are tutorials online) or go straight to a professional shop for hassle-free repairs. Safety first, after all. Regular maintenance, like changing the oil, can prevent this issue, and using high-quality sealant works well.
