driveshaft oil seals s70

hi all i have a 1997 s70 which started leaking oil from the os drive shaft oil seal, which i replaced about a week ago (oil seal), but now it leaking again?? can anyone give me a clue what ive done wrong please or any tips for this week for secound go. thank you:hissyfit:

Are you sure it's leaking from there? Engine rear main seal and turbo return line leaks look like drive shaft leaks as the oil seems to spread everywhere.

assuming its all in straight then its possible you just have a dodgy seal....
