DAYTONA BEACH, Fla. -- Austin Dillon could be in line for another penalty.

Dillon's No. 3 Chevrolet failed a post-qualifying inspection at Daytona International Speedway on Friday after NASCAR officials found an open cooling hose in the cockpit, which would boost aerodynamics.

The announcement came after Dillon claimed the pole for Friday night's Nationwide race at Daytona. It also came four days after NASCAR penalized Dillon because his car failed inspection after his victory last week at Kentucky. Dillon was docked six points in the standings Monday, dropping him from the top spot.

Dillon earned his first career Nationwide victory by leading 192 of the 200 laps. NASCAR ruled afterward that his car was too low.

After Dillon's disqualification Friday, Ricky Stenhouse Jr. earned the pole.

Dillon had his time thrown out and was slated to start last, with all other drivers moving up a spot.
