blew my turbo ... i think !

[rdodger]

so before i order a new turbo i was wondering if someone could set my mind at ease . today while kinda heavy on the accelerator i got a wooosh sound and white smoke from the exhaust . pulled over and shut her down . popped the hood and started it again and there was a klak klak klak sound at the turbo like something was broken inside and tumbling around . so i shut it down again and unplugged the harness at the turbo then started it again and the klak klak klak was gone and the smoke from exhaust went away after a minute or two . so like i said i'm just looking for some expertise on whether its actually the turbo or not . thanx for the input in advance .

Im by no way an expert but it sounds like as you have described that it has to be coming from the turbo since when you took the harness off of it and run it it didnt make the crappy noises. You might try taking the intake off and looking at the turbo vanes maybe messed one of them up. Hopefully someone else with some more expertise will chime in but theres an idea for now anyways.

so i took the intake off the truck and looked at the turbo and it spins ok and from what i can tell (its dark) everything looks like its ok , its my first time looking at a turbo so who the heck knows but from the pics ive seen it looks ok. i had a buddy of mine say something about an injector and because i was on the throttle pretty good when it happened it makes me think . anyway when i unplugged the harness at the turbo the sound did go away but i was just idleing and made the klak sound at first but went away after a sec . PLEASE any help or advice is greatly appreciated cuz i cant really go the mechanic or stealership route right now . thanx guys

Rdodger,

can you check to see if the truck is throwing any codes? A auto parts store should be able to pull them for you. If it's a injector the computer will tell ya.

For the turbo noise, you may just need to drive it again and see if the noise comes back.

i checked for codes with my sct flash device and nothing , not even with the maf sensor unplugged . i didnt wanna drive the truck cuz ive heard so many stories about guys who pushed them after an incident and it cost them a motor so im not sure what to do ...maybe i'll just bite the bullet and take it for a quik spin tomorrow and see what happens . if i do drive it should i plug that harness back into the turbo ? thanx for the help guys i REALLY appreciate it

Is there excessive up and down or side to side movement of the shaft inside the turbo?

[rdodger]

nope not that i could tell

Sitting Still idling with the turbo plugged in your Vains in the turbo are fully closed. unplugged the turbo would be fully open. Meaning that your turbo vains are furthest away from the turbine impeller. My guess is that you could have a seal out on your VGT Control shaft that rotates your unison ring. the fact that it stops smoking after you unplug it makes sense that it is not pressurizing the VGT Control valve any more letting the oil just lube the bearings and return to the oil pan.

Also you may want to check your clamp ring on your turbo and make sure it did not give way. If you heard a "wooooosh" sound it leads me to believe that you either have a broken clamp, or a boot that is torn.. Check them well for cracks that may have happened during high boost.

Does the truck actually idle and run ok or can you feel the engine missing out? This is what mine looked like after it blew. This was on a stock tune also. I could move the shaft enough that the blades would hit the case.
