EWB555 Posted December 31, 2012 Share Posted December 31, 2012 I noticed the Turbo on my 95 E7 400 is leaking oil in the center. Its a pretty decent oil leak, dripping down on the injection pump. Is this a sign of potential Turbo Failure? The leak is around where the oil fill tube connects to the Turbo below is I picture I pulled off the net to show where the leak is (its not my truck but the same setup). Truck has almost 450K on it, the turbo seems to have markings on it like it was engraved from a junkyard, I've owned the truck for about 18 months so I dont know the history. Last time I drove it it was putting out 30lbs of boost under load, I seem to recall it used to go up to 35. (I dont drive it that often)Appreciate anyones thoughts!

staxx Posted December 31, 2012 Share Posted December 31, 2012 Gasket if only coming out around tube if driping from rear housing clamp the seals in turbo are worn or truck is idling too much ,the turbo seals need a little positive boost pressure against them to seal well , and at idle there is no boost.
