Vacuum Leak or Increased Air Flow?

I own a 2004 F350 Long Bed. This is my first diesel, and I am little concerned about a couple issues that have come up. In the interest of brevity I'll stick to one question at a time. I recently changed my air filter out and replaced it with a new Fram. After I man handeled that rediculous setup of a system that some genious engineer should be slapped silly for I noticed what seems like a vacuum leak coming from somewhere around or under the turbo. I got the new air filter in OK and it seems to be seated correctly. I can't exactly pinpoint the leak and am concerned that I might have knocked something loose in replacing the air filter. The truck seems to run just fine, there is just a very obvious sucking sound. Anyone have any ideas? I am at a loss.

Well, beyond the advice of avoiding the fram filter, you don't have vacuum to cause a vacuum leak. The filter's different flow characteristics (less filtering restriction) may just make the air intake a bit louder. I can always hear my engine pulling air with the hood open. You may want to double check that your "filter minder" is still properly secured.

Good luck and enjoy your truck!
