This is not good news. The shop that is telling me that I need this said they knew of no other MB that required a crank removal to do the seal. Is this a true statement? I asked the mechanic if he had ever done this on a 6.3 and he said yes and it did not require crank removal. isn't the 6.3 the same block? (I am hoping that the procedure would be the same)

thanks
