Hendrick, Gibbs face engine problems at Daytona

Those powerful, seemingly unbeatable Hendrick Motorsports cars had major engine problems Wednesday during practice for the Daytona 500. Two-time defending NASCAR champion and pole-sitter Jimmie Johnson, four-time series champ Jeff Gordon, Dale Earnhardt Jr. and Casey Mears all were forced to change engines because of a lifter problem likely caused by a bad batch of coating. Scott Riggs, driving for Haas CNC Racing and using Hendrick power, also swapped engines. (link)
