BIG PROBLEM!!! PLEASE HELP!!!

[tonypagnano]

ok, so today i drove my truck(99 f350 AFE intake, straight pipe, gauges) to school, everything was fine and normal, drove it to lunch then my aunts after school, againe everything was fine. well i fired it up to go home made it about 100 yards from my aunts and when i let off the throttle(was at about 1/4 throttle) it started knocking and dumping out dirty gray/blueish gray smoke from the exhaust. i got it into my driveway , i live right down the road, and shut it off. the oil pressure and all the gauges are reading like normal. the sound didnt appear to get any worse. i popped the hood and noticed a small amount of oil behind the turbo where the exhaust manifold connects to the part that goes to the turbo? if you guys have any ideas please let me know! this sucks!!

bump for exposure. Blue smoke is oil burning

[tonypagnano]

how do i bump? thanks

Maybe your turbo is in need of replacing or maybe you have a bad injector. Not sure though. A BUMP is a way to get your thread to the top of list. Hence you get bumped to the top of the list.

Just type 12 characters and make sure you put BUMPin there that way people know that you haven't already gotten the help ya need. BTW BUMP

lol but dont do it every 60 sec.... im sure someone will be along shortly to help you out... oh and BUMP lol

I hate to say it or think it but it sounds the same as when the turbo took a dump on me in our 99 ... if you rev it to spool the turbo does it make any noise?? pull the tube off the turbo inlet and check the compressor wheel.. I hope it dont look like this
