Try applying the brakes in gear and hold them while giving it gas and see if the same noise is there.

If so get someone to do the same while you look under the hood or have some one look under the hood while you do it.

This is how we verify which mount is bad in a FWD car with a clunk.

I havent checked the mounts. Another thing i noticed is the turbo itself is slightly smoking from under the turbo blanket. The first time i drive it i just thought maybe i got some oil on it. But is was doing it slightly today.

I think i may have found the source of the noise. I think my turbo is hitting the hood. I noticed on the underside of the hood was a spot where the insulation was rubbed off and a bare metal spot like something had been rubbing against it. It kinda makes since. When the engine is a high load i am sure it is arching over making the hood come in contact with the turbo.

I adjusted the bump stops on the hood and i will give it a try tomorrow.

Hard to diagnose something like that without video. And I know how much you like taking video of your truck

Yeah i never thought this would be an issue. Also the new i take is allso pretty freaking close to the hood as well.


The turbo hitting is actually a relief an makes somewhat sense given how loud the noise is.
