Hello, I'm fairly new here and have a 2010 Limited ecoboost. When I got it in September of last year the engine and both turbos had been replaced at about 80K and it now has 150K. It started smoking a little, then I heard some squaling from the engine area, and now it smokes ALOT. The front turbo has oil leaking from it, but I can't tell if its just the drain tube or leaking from somewhere else. The rear doesn't appear to be leaking.
My question is, is there any way to tell the turbo has failed without taking it off? Can I pull the intake hose and feel for shaft play? It doesn't look terribly hard to remove but I don't want to pull it is its unnecessary.
I appreciate the help in advance
