Hendrick engine problems caused by bad parts:

Hendrick Motorsports officials say a bad batch of parts led to engine failures by #88-Dale Earnhardt Jr. and #5-Mark Martin in Sunday’s Sprint Cup race at Auto Club Speedway in Fontana, CA. “Both cars had valve train failures that were related to a specific batch of parts from a vendor,” said Doug Duchardt, HMS’ vice president of development. Duchardt said the parts were not restricted to use by Earnhardt and Martin, whose cars are prepared out of the same building. He said they also were used by Hendrick drivers #24-Jeff Gordon and #48-, as well as lease programs such as Stewart-Haas Racing. Earnhardt finished 39th and Martin 40th after both lost their engines within 25 laps of each other. Gordon finished second and Johnson was ninth, combining to lead 138 of 250 laps. #14-Tony Stewart was eighth and led three laps. “So we’re glad it wasn’t more widespread,” Duchardt said.(ESPN)(2-24-2009)
