Denny Hamlin said he's "concerned" with the reliability of his Joe Gibbs Racing team's engines heading into the Chase, but acknowledged there was "not a whole lot I can do about it."
"Just kind of hope and pray that it holds together for us," he said Friday at Pocono Raceway.
JGR's motor program has been plagued by several issues this year, and the team recently brought in Toyota Racing Development (TRD) – which supplies engines to the other Toyota NASCAR teams – to help diagnose the problem.
"I think that they're making strides and trying to get better, and it's not from a lack of effort by any means," Hamlin said. "Obviously, we need to lean on those guys at TRD to try to help us work through it, because it looks like their engine program has gotten reliability sorted out here in the last couple of years."
JGR has had three DNFs due to engine failures in Sprint Cup races this year, but there have been other issues during the race weekends – such as Hamlin's blown motor during Brickyard 400 practice last week – that have called the team's mechanical reliability into question.
