Mod motor vacuum leak???

Do all modular motors sound they have a constant vacuum leak? I’ve owned 3 so far and they’ve all sounded like they have a giant vacuum leak. But they run fine and idle great as long as the plugs and coils are good.

Same here. Never heard a vacuum leak from the ones I've owned. Have heard from some that I've worked on, but then fixed it.

Maybe I’m just hearing the throttle body. I’ve had 2 V-10s and a 5.4 and they all sound the same. Plus they all ran/idled smoothly unless a coil or boot was bad.
