Cold Weather Turbo Noise

[JackHerman]

This is my first time posting. So much info on this site I have usually found what I need, but this has me stumped. I have recently noticed with the cold weather my engine/turbo has been making a different sound when the engine is still cold. The sound starts when the turbo kicks in and sounds like pressured air being released making a more pronounced "air" whistle and not the normal turbo whistle. I can barely make out the spinning turbo sound. It becomes really loud when I really step on it, much louder than the normal turbo whine. Is this normal? It almost sounds like something leaking air and the forced out air/exhaust is making the whistle. My truck is stock except the KORE leveling kit and 35 BFG muds. It's the 325 HO 600 2004. 5. Thanks for your help. I figure it is worth getting opinions before wasting time at the dealership.

First of all welcome to the TDR.



It sounds like you need to check your intercooler hoses for leaks. The clamps are notorious for becoming loose and creating a boost leak.



Hope this helps ya.

That makes sense. The sounds seems to be more on the drivers side. I will check the hoses out. Thanks!
