sure the seals are bad? is the bike lowered? oil level higher then the turbo shaft? breather blocked? sounds like the oil is just leaking past the seals when it is parked. most will do that if the oil level is higher then the turbo shaft. if it is cleaning out and does not continue to puff like a freight train why change it. raise the bike or lower the oil level if it is too high.
It still smokes some when riding, but its smokes like a motha when u first fire it up. Thanks guys I'll check into it a little more.
