Turbo noise
 

I replaced all my turbo lines and now when the second turbo should kick in there is a sound like a large leak. Not a hissing sound but a load Shhhhhh. I have checked all the lines and they seem to be all correct. What could be wrong
Thanks

I have loud axx hissing sound comming out from my turbo, Its probably screaming out for rebuild, but it sounds soo damn cool....haha

jay,

generally the noise you describe is created by a leak downstream from the turbos primary air output towards the engine... a loose clamp at the intercooler or between the intercooler and the throttle body.

good luck... it is generally relatively easy to fing.

I had something similar happen. It ended up being the vacum chamber that was attached to the UIM. It had a crack in it and blew more hot air than the average woman.
