Last time we heard from Fox’s Gary Gastelu, he was reporting that his test Z06 gave up during his track run in a spectacular shower of oil and grease and bits and fun.

Now, he says Chevrolet has told him what went wrong and it’s a familiar story:

After bringing it back to Chevrolet HQ for inspection, the engineers determined that the likely cause was a piston connecting rod bearing that was damaged by debris in the oil that was left behind after tapping the threads for the oil filter. Once a piece gets jammed in there, it starts creating more debris, which keeps making things worse until finally … kablooey. In this case, it took out a few more pistons with it.
