2010 Vw Jetta Oil Filter Housing Leak. If the oil drain adapter (t40057) is removed, the valve is closed again. The transmision fluid also looks the same as the oil and if the car is old (which it is) the axel seals tend to start to weep while in motion.hope this helps.
They call with my estimate and tell me i have a major oil leak. i park on gravel/dirt, so i had no clue. Otherwise, it's a fairly easy oil change. If it is damaged, it means low oil pressure and a leak.
