Race car rolls

This car ran 8.20s earlier in the day at 165 mph. He has been fighting oil leaks the last couple of races and they didn’t jet him run. Last time back it had a slight leak that the staff saw but they still him run. Track hasn’t released any info yet. It started smoking bad b4 it rolled. Speculation is that the oil leak got under the rear tires then that was all she wrote. As for being a fast Ford it isn’t. It is LS powered. Kim
