I'm trying to figure out what a loud sound is coming from the breather box, when taking off in low gear and after getting up to about 2-3k rpm and letting off gas peddle I hear a sound like either a lot of suction or blowing coming from the breather box. I can also be sitting still with the brake pressed and rev it up and when letting off the gas peddle it will do it. Could it have something to do with the Turbo?
Thanks!
Also it does not happen unless it is in gear.
