The throttle leaks oil. Do you have EA2 1 1 1.4?

If it's just oil leakage, this situation, drop by drop leakage, is more serious. Because the amount of oil in the gearbox is certain. It won't be long before you just let it out. The bearing is damaged and the gear is slightly worn. The worst case scenario is that the gearbox is scrapped. It is recommended that you repair the oil leakage as soon as possible. What if, like you said, it's just the sealant leaking? Replacing the gasket is very low in cost. Repair it early, so as not to lose big because of small.
