bdws6 Posted April 16, 2014 Share Posted April 16, 2014 My 08 lgt is making a weird metallic whooshing sound when I accelerate. Any thoughts on what it is Link to comment Share on other sites More sharing options...
rob-2 Posted April 17, 2014 Share Posted April 17, 2014 Check the turbo and be light on boost. You likely have a failing turbo. When it goes normally the motor does too. Link to comment Share on other sites More sharing options...
bdws6 Posted April 17, 2014 Author Share Posted April 17, 2014 It sounds more like a build up of pressure then a whoosh. It kind of sounds like a turbo diesel truck. It just never sound like this before Link to comment Share on other sites More sharing options...
MrTris Posted April 17, 2014 Share Posted April 17, 2014 You don't want it to end up like mine, below. Seriously, pull your DP and stop driving it, ASAP. Unless you wanna blow about 7k just to keep your car on the road. . Link to comment Share on other sites More sharing options...
bdws6 Posted April 17, 2014 Author Share Posted April 17, 2014 I have been looking around other threads. U guys think it just might be a boost leak. I don't notice any power loss Link to comment Share on other sites More sharing options...

Unless you wanna blow about 7k just to keep your car on the road. . ^^^THIS if you're hearing metallic scraping or whooshing noise from the turbo. Generally means that the turbo has cashed it in and that's the cash register making the noise. If you continue to drive it, you'll be right in the neighborhood of $6K and that's a shitty neighborhood to be in. Link to comment Share on other sites More sharing options...

Nrw Posted April 17, 2014 Share Posted April 17, 2014 Stop driving. Drop the downpipe and check the turbo. Hope it spins freely and there is no shaft play, if not prepare your wallet. Link to comment Share on other sites More sharing options...
bdws6 Posted April 17, 2014 Author Share Posted April 17, 2014 Ok. I checked my air box. I did not have the bottom in place and it was open. I almost don't hear the sound anymore only when I really listen for it. It's probably Been making that noise for years. Yeah I probably should have mentioned I just replaced my air filter. It's not really a metallic sound anymore. It just sounds like air sucking in then blowing out when I let off the gas. Link to comment Share on other sites More sharing options...
