The solution we came up with was elegant in its simplicity. The automotive equivalent of a diaper was zip tied around the breather. This would catch any errant oil and keep it off the headers. After this event we will need to design a proper breather system, but for the moment it did the trick. To fix the driver’s side cover we “borrowed” an oil cap from James Shipka’s Chevy truck. Hey, we gave it back at the end of the day!
