Anewman, Nascar strongly subscribes to the fact that there should be a level playing field. As such, there are things that you cannot do to your vehicle to get it faster. Although, I'd say the field is more level for some than others (cough cough).
Michael Waltrip's manifold appeared to have a substance on the inside of it. His crew chief was asked to change the manifold, which he did with a new one in a box, and it also appeared to have a substance. Then they made Mikey use a backup engine, in which he qualified 24th. That manifold also appeared to have the substance.
Crew chief said it was oil, but oil shouldn't be in the manifold. It's suspected that it's sterno, which can boost the speed of the car short term-and that it usually burns off without any sign that it was there.
The other two are due to improper plugging of a hole in the rear wheel wells. There can be a hole during the race to bring air into the car to cool off the driver via a tube. For qualifying, it must be covered. Kasey's was covered with duct tape, which *somehow* got slashed and ripped apart. Matt's was covered with a piece of steel, but it was secured from inside the trunk, not on the outer part of the wheel well. Both drivers had the tape or steel in their trunk. Nascar feels that the hole being uncovered gives one an unfair advantage.
This year is shaping up for there to be a LOT of infractions...
