Motors, they are a changin’.

Or was that “times”? Well, that wasn’t the case in Daytona this afternoon.

It would seem that teams running Hendrick engines, at least 6 (includes Nemecheck and Riggs), would be changing engines before the Duel’s tomorrow afternoon.

But wait, we’re not stopping there. Toyota is also have problems with their engines. In fact, the exact same problem. To the extent that TRD is sending new engines straight from California, post haste.

The problem, for you engine techs out there, is that the coating on the cam shaft is coming off, getting on the lifters and filtering through the engine.

Clint Bowyer is also changing an engine today, but it was unrelated to the above problem according to SPEED.

What this means is that the teams who have changed engines prior to their Duel will have to start at the back of their assigned heat. Once the Duel’s have run, all teams may freely make an engine change without penalty.

UPDATE: All four Hendrick Motorsports drivers -- #48-Jimmie Johnson, #24-Jeff Gordon, #88-Dale Earnhardt Jr. and #5-Casey Mears -- will start in the back of the field in Thursday's 150-mile qualifying races for the Daytona 500 after their engines were replaced on Wednesday afternoon.
Jeff Andrews, HMS's head engine builder, said the problem appears to be related to a batch of lifters.
The problem also was discovered in the cars of #78-Joe Nemechek and #87-Kenny Wallace of Furniture Row Racing, and #66-Scott Riggs and #70-Jeremy Mayfield of Haas Racing.
All four are powered by HMS engines. But the problem wasn't contained to HMS.
Toyota is bringing new engines from California for #44-Dale Jarrett and #84-A.J. Allmendinger. Joe Gibbs Racing is bringing new engines for #20-Tony Stewart and #96-J.J. Yeley. Yeley, who drives for the JGR satellite team Hall of Fame Racing, has replaced two engines since arriving at Daytona.

Looks like we may have a full inversion of the field before Sunday!

The problem, for you engine techs out there, is that the coating on the cam shaft is coming off, getting on the lifters and filtering through the engine.

Well now that's really confusing unless the coating on the lifters is hard enough but the finish is abrasive to the camshaft finish.
