Finally got that stubborn 6.7 Powerstroke to stop smoking after chasing it for three days... turned out to be a single, tiny boost leak at the up-pipe flange.

Was it really that big of a deal?

My buddy chased a similar leak for a week on his old Duramax.

Sprayed soapy water, found mine in minutes.
