In addition to what JStieger says, check all your boost lines to be sure you didn't simply blow a boot off.

Where all do I check for the boost lines,my main hoses from the turbo to the intercooler seem to be fine,but I wonder what is making the truck run like crap,its a steady stream of white mixed with black smoke,and it just lost a lot of power

 

[rbattelle]

What about from the intercooler to the intake horn?

[JStieger]

did you check your oil for diesel?



Your signature says you don't have your stock turbo anymore, but maybe you still blew it up. Did you pull the intake hose off the turbo inlet and check for leaks, shaft play, etc? Oil running out the exhaust?



How high boost did you get to before you heard the "small boom sound"?

I was all out at 50lbs of boost,no I did not check the turbo for shaft play or oil in the exhaust,but if the turbo went out would it lose that much power and have smoke continuesly??

YES!

I havent tryed to start it yet since I turned it off after it happened,what if it dont start,do you think it would still be the turbo,also I checked the engine oil and the radiator antifreeze coolant,everything looks good

im pretty sure it will start but i wouldnt let it run for too long. its possible that you 1 lost the turbo, 2 popped a head gasket, 3 craked an injector. and the list goes on. but those three would be where i would start.

 

[rbattelle]

I agree with what RobertP says. These trucks will run - sort of - with no turbo. But don't let it run long like that, because if the turbo is shedding particles you can ingest them.

I agree with ryan these truck will run without the turbo as I have found on by mistake. but egts will be high and so will coolant temps (i dont have egt gauge). when my turbo plumbing let loose it made a small boom.



some trucks I believe are notorious for breaking intercoolers with alot of boost i dont recall which cummins equipped trucks tho

If the turbo went south it is possible to ingest oil on the intake side. To be safe, pull the intake elbow off the manifold and start it. Or pull the intake hose off the elbow. Then if it is spitting oil or turbo parts you won't end up with them in the engine.

Be sure you keep your hands away from the intake! The suction is strong enough to really hurt you, especially if you get a run away.

I dont know what the deal is,I started it up and it runs fine. doesnt show any codes or anything,as soon as I started it up again the codes it was showing are cleared,I dont know if it had a brain fart or what... I will keep you posted,,,,thanks for youre help

i would still check into all of the above symptoms before really driving it. i believe in the phrase, its better to be safe than sorry.
