We've had a few posts over time regarding funny sounds coming out of the new 6.4L Powerstroke. The turbos make a distinctive whistle which is easy to hear. However, recently I have been hearing a particular sound which sounds to me like wind howling through a crack in the window. It's just a hooooooooo sound. Like something is sucking air. It seems to happen much more before the engine is at operating temperature. It also stops when I let off the accelerator. I've checked the air intake including the air filter box to see if maybe something is not snug there. Found nothing. I haven't checked yet if it is specific to the A/C being on or something like that.
Anyway, I was just wondering if this sounds familiar to anyone. The fact that it decreases after a while concerns me a little in that maybe it could be a turbo issue. I don't know what a turbo sounds like when it's going bad but after my initial major issue with this truck, anything is possible. It's also possible it's just something as simple as the air filter box not sealing very well. The clamps are a bit loose. Anyway, any ideas would be welcome.
