Been a while since I visited because I ain't had no problems. Last Wed 2 July my truck started making a whoosh or blowing sound when the turbo gauge in dash showed 10psi or more. I have checked my y pipe and down pipe and there is no soot on firewall or anywhere on pipes. Changed my air filter and it still is making the same sound. Anybody help me with this? It's hard very hard to find anybody thT wants to work on this 6.0

 

6.0's make me money, i will work on it. LOL does the truck still build the same amount of boost as it did before the noise started. the OE intercoolers have flastic end caps that are notorious for blowing out the rubber seal and causing a large boost leak. pressure test your intercooler.
