I have my manifold off my 2001 6.0. I bought a new one because I thought it had a vacuum leak, but it did nothing and turns out it was a hose the whole time. There was a pinhole in out of the caps on the side of the intake and I got that sealed up. I think one of the 2 tabs for the map sensor are broke, but thats the same way my new intake is and it doesnt cause any issues. There are no leaks as far as I know. I picked up a new intake for like $75 bucks, so Ill sell this one for $50 plus shipping.
