Im lost. I will do a boost leak test tomorrow but just wanted to get honest opinions on what you may believe it to be. Just give it to me straight LOL. smh



Blown Turbo? '09 Cobalt SS - YouTube

 

sounds like a blown turbo to me...but the RPMS aren't even going sky high when you gas it hard

 

I think you may have a hose blown off. happened to me on a diesel truck I was working on, took it down the back lane, and apparently the hose clamp wasn't tight enough..... rev rev PSSSSHHH. pull over, and inspect, hose is seperated. making the turbo spool immensly loud. same as can be heard in your car In MY opinion, I could be wrong.

 

Thanks for the responses! Im hoping that its anything but a blown turbo. but hey it is what it is. I can hopefully figure it out tomorrow. it drives ok, it went above 5 psi a little while ago without me gettin on it but that was it. im just dreading the worst case scenario lol cuz it couldnt have come at a better time. Merry Christmas everyone!

 

are you blowing any smoke from the exhaust??? that's one of the easy ways to tell if the turbo is blown, you probably just have a leak somewhere

 

sounds the charge pipe came off or ic blew out. you can hear the turbo spooling in the video so it's not a blown turbo

 

umm if his ic pipes or charge, came off his engine light be on throwing maf code.. and in the video didnt see the light unless it on now/

 

Not true at all. It depends on how long it has been blown off. Mine didn't throw a code for 12 miles one time when mine was 50% off the intercooler.

Stay the hell out of boost until fixed.

 

there is a cel on in the video

 

pretty sure your problem is at .33 seconds! lol

Sounds like a turbo gone bad to me but I'm not a turbo owner. just a hunch

 

When my charge pipe came off it sounded like a jet engine. Seems to be what's going on. Quit revving the engine and go over the entire charge pipe system and intercooler.

 

As others have stated, check for major boost leaks, particularly intercooler and charge pipes.

 

Again, I appreciate the responses. I checked for the white smoke and the part that sucks is that its a little cold in Houston, TX today so when i give it a little gas at a stop, a little white smoke comes out but i think its because its cold outside. Plus I have a catless dp. When i reved it in the garage or when i drove it a little, no smoke came out the back. Im gonna do the the check today and let everyone know what it was. I dont have a CEL yet. Thats my TPMS light on in the video. I was told from a truck mechanic that it may be the intercooler. Hope not because I just purchased it from treadstone not even three months ago.

 

If you have a different intercooler then my bet would be on clamps aren't tight on the intercooler.

 

if you have a treadstone ic its most likely not a blown ic.....thing is built like a tank. check your charge piping and make sure the intake is still connected to the turbo. it sounds like the turbo is spooling to me. mine didn't throw a code immediately when this happened:



have you even looked under the hood for a quick visual?

 

its a boost leak......case closed, takes 5 seconds to look and check if any piping is lose before you go around panicking that you have a blown turbo, if the turbo was shot it wouldn't be spooling like that and you would be blowing visible smoke from the seals being shot

 

wow!! thats crazy lol. But yea I checked the K&N SRI, and made sure all the charge pipes are on snug. Even the ones to the IC, but it was late and dark so I couldn't inspect every one. Everything "looked" ok. Doesnt mean that a coupler didnt burst or not. I'll be getting to the bottom of it today, but the sound was so crazy loud that i didnt think a boost leak would be the cause.

 

Rule #1, dont panic.....and i broke it lol

 

Off topic but what the heck is that big box on your engine?

 

thats a HHR intake

 

Blown passenger side IC end tank. I don't know where that dog-bark sound came from, though. I don't know why you're saying that you hope it's anything other than a blown turbo. A turbo will cost you less than an intercooler. Sounds dumb, I know.

 

Ah ha! Didn't realize that! Tyx.

 

gotta look out for them red cobalt owners

 

 

its my twincharger...got it from ebay for 20 bux man added about 100whp
