I had my friends put the rear crank seal on my vehicle 2 times, but I could not prevent oil leakage, the master said that he came from the crank seal again. He said he missed the rear crank seal when I took him to the checkup for 307 mi. There is a leak at the point where the gearbox and engine meet. It is not the gearbox oil that is the engine oil. Since the gearbox and engine are at the junction, the service said that the rear is cranked. I bought the felt from the service. Today, my master changed it again. but tomorrow will be kidnap tomorrow, for now the car lies in front of the house. I would appreciate if anyone answers my questions below.1-Is there any other wick to be fitted with crank felts or just goat will be installed because my master just wears the seal2- Will the oil leak from the rear crank than the rear of the transmission and the engine (there is no dry oil leak on the side of the oil cartel) 3-back crank seal is changing, some people should apply liquid gasket. .5- Some friends say that when the new crank seal is installed, the kidnapping from the previous felt will take some time, and when the new felt is fully seated, the kidnapping will stop automatically. Do you think this is possible? If there is a leak again, it would be a problem if I use it in this way because the leak has been leaking for 2 weeks. If the infiltration continues, it would be a problem for me to use it like this, thank you very much.
