I got my truck back from the dealer they put in a new motor and turbos after a rod poked some holes in the block
Now i have this Moaning sound from the intake at only 2K rpms. I set the brakes so it won't take off and had a friend listen were it's coming from
I removed the air filter and the sound is in the intake It sounds like your blowing into a Tuba .
I have the stock intake it did not make this sound with the old motor . any ideas Ford don't know ether They thought it was the cats wrong

If you think something is off, take it back to the dealership.

I got it when they put the motor in a plastic fitting broke off at the waste gate hose so the waste gate was not working correctly
