Default My turbo is making funny noises

okay so since my last thread was a fail... a few days ago my car started making weird noises on a cold start.. came from the turbo side.. sounded like marbles in a blender.. so today i took the inlet hose off and there was no shaft play. the turbo is basically brand new maybe 50k miles on it. so as far as i know i think its a ball bearing. so what is my best option.. im not made of money so i think im going to get a rebuild kit from gpopshop. then sell this car soon after for something more reliable.. my car has been just going down hill day by day. my Airbag light comes and goes.. i get 14mpg city. i think i have a vac leak. my coolant some how keeps disapearing. and now the turbo is giving me problems. and i know its not blown its still pulls hard.. no white smoke and theres no drill noise

you sure its the turbo? you sure it couldnt be a bad cam chain tensioner? the only reason a turbo would fail in 50k miles would be either it was a chinese knockoff or it was starved for oil (gunked up feed lines).

ko3 aren't ball bearing turbos...right? But if there isnt any shaft play up/down and in/out then chances are it isnt your turbo, nothing else to make noise in a turbo..

theres very very very minimal up down none in out and none left right... and yes they are Journaled Bearing turbos.

i forgot to mention that it only happens on a cold start and goes away after about 3 min

could be a partially clogged oil feed line starving it until it warms up and the oil gets thinner.

In my current financial state I can only hope its clogged oil lines.. But I do have a TT dunno how they can get clogged if I'm letting it cool down.. Tuesday ill order some oil lines and hope that fixes it.. Its driving me insane. Where's the best place to get them but not get ripped off?

I would make sure all of the exhaust manifold bolts are tight. I had a small leak between the block and the mani that sounded REALLY wierd. Can't hurt to check.

No mine actually sounded like the jetsons mobile, but the main reason I say this is that mine also made wierd noises just untill the engine warmed up.
You might want to take you cat off and see if you have a loose chunk in there that's bouncing around, also when you do that you can take a look at the wastegate flap to make sure that isn't loose either. I doubt a clogged oil line would make a sound that's loud enough for you to hear.
