getting a fluttering noise from what i believe the turbo

[bman2033]

i had no issues with this until i did my last oil change and now i get this weird fluttering sound from infront of the steering wheel which i think is the turbo, but i have no idea whatit could be i can hit stock boost psi which is normal but, i m just wondering if it is that the turbo may not be getting any oil or verlittle oil like having air in the oil lines. any suggestions???

when do you hear it? when you let off of the throttle?

no when im mashing the gas, this sucks cause now i have all these thoughts goign through my head.....coul dmy turbo be bad, boost leak somewhere....but i have the s15 turbo and i got it about 8 months ago.

This is probably a dumb thing to post, but are you sure your just not hearing your turbo spooling. If thats not it then you may have a boost leak and/or your blow off valve is leaking or stuck somewhat open.

well now i was driving home today and now i hear a completely different and worse sound the noise now sounds like a gasket leak and now i hear this clanking noise kind of where the transmission is. i hope my car is not falling apart. is there anyone in maryland that is a mechanic and knows what they are doing and can check my car out i will pay for any labor i just don;t want to pay the high price that a shop would pay.

couple things we nerd to know.

atmospheric or riculated bov?

and the clanking, have you gotten under the car first and made sure there are no missing bolts or lose mounts?

check the turbo housing bolts to the manifold, mine was making a weird sound like the turbo itself was messing up, but i tightened up the bolts and boom.. problem solved.. just saying it might be that

My T25 was making a sound similar to that and it turned out to be the bolts that hold the compressor housing to the exhaust housing of the turbo. Keep us posted.
