I recently put an EGR delete on my 2005 f350 and now I have What sound to me is an air leak ive looked and felt almost every where I took parts off and I can not find anything, the noise get louder as I hit the gas. i think it is some where on the intake or the turbo area. does any one know what the hell???
there could be a few different places that it could be coming from around there. try getting a spray bottle with some heavy soapy water and spray it around all your CAC tubes around the area you hear the sound. if you see bubbles you found the leak. there shouldn't be enough pressure in the delete to cause the hiss. could also be that your down pipe isn't seated all the way against your turbo. they can be a bear to get to seat properly sometimes. let us know what you find out!
Thanks!! so i figured it out and fixed it. it was one of the up pipes going to the turbo. it just was not seated right on the turbo , after a hour of fighting it to seat right i got it and the noise is gone. thank god. it sound like i was driving a sweeper around town lol .
