What's this sound

[petewim]

First time here on SLI, i have a 05 lgt and I just replaced my turbo and now my car makes this noise. I replaced it because it blew up from that damn banjo bolt filter. Luckily it blew up on the exhaust side and left the intake side undamaged. The sound only happens while driving, I can Rev it up in neutral or park and sounds fine. (I think the blow off valve sounded louder before I replaced the turbo, in netural or park) it's sounding like coming from the pass side. Any help would be awesome. I'm really hoping it's not the motor, I don't think so because it only happens under load but not while power braking. Really hoping I just need to a just something this is my first turbod car so I'm unsure what ajustments need to be done.

Video isn't working for me.

Did the shaft break on the turbo? And if so did you drop the oil pan to clean out all the metal from the shaft failure, replace the oil cooler, remove and clean out the avcs actuators and their associated oil lines?

yes the shaft broke, but like i said the intake side was still intact it actually still spins freely. i replaced the oil line and the banjo bolt w/ filter, and changed the oil. i took another video this morning but it wouldn't upload. I was unaware there was an oil cooler on my car and i'm unsure what the AVCS is. I took another video this morning but it wouldn't upload, but the noise only happens when the turbo is really spooling up (unfortunately i don't have a boost gauge so i don't know at what psi it starts). while in park or neutral i can rev without any unusual sounds.

You are in for a world of trouble if you don't do the things I mentioned in above.

There is far more information on that site about your car than there is here, join and read up. It could save you a very costly engine replacement.
