turbo leaking oil! shot oil seal?
 

i just installed a t78 kit that i bought second hand..and now its leaking oil from the hotside and cold side and smoking like crazy..what could be the cause because the person i got it from said it was running perfectly before he pulled it off his car..and i didn't even tampered with it..did he sell me a turbo with shot oil seals..or is something just loose in there..thanks.
