Fiat was down on power last 1/3rd of the day on Sunday at Thill...
Post race tear-down revealed this as the likely the culprit.
As you can see, this was a relatively new gasket (replaced before Buttonwillow in August). We lost the gasket in the same place at Thunderhill back in 07, and there's a significant burn mark on the block between 2-3 cylinders, which is just going to eat the next gasket.
We also filled the catch-can with sump oil, meaning we were blowing some serious pressure past the rings into the crankcase. Maybe a broken ring or piston skirt. Once we pull the bottom end apart, we may find this block is toast.
Oh, and our exhaust manifold is cracked in about 4 places.
And our front rotors are warped.
And our oil-can scoop is broken.
Good times.
