Hello !!!
I have a 1991 350 SDL and for the past two months I noticed oil is dripping from the turbo drain hose down to the pavement. What causes that? Please educate me !! Is that drain tube suppose to be open like that or it suppose to be connected to the oil pan?
For the past two weeks I also hear the turbo making a "buzzing" noise as well..at least I think its coming from the turbo. Could those two events be related ?

Thank you all for your help !!!
