How a Single O-Ring Almost Ended a Race Weekend

Our race weekend at New Jersey Motorsports park was months in the making and the MX-5 Cup car known as Marylin finally felt solid. We arrived late, so the plan was to pull the car off the trailer, complete an ABS calibration, and then head back to the hotel to get a little rest before the afternoon qualifying session.

The MX-5 had other plans and started steaming from the back of the cylinder head after the ABS test.

The qualifying session was just a few hours away and the leak appeared to be coming from an unreachable spot between the cowl and transmission bellhousing. Online diagrams showed an O-ring at the joint that was leaking but the closest Mazda dealership had none in stock. If we were home in North Carolina, the move would be to go to the sole local mom-and-pop store and raid their case full of various o-rings until we found the right one, but a quick Google search showed that all we had around us were national parts chains.

These stores had no such case and their computer system showed no rear water outlet o-ring for the MX-5. Time was running out. We had to qualify. We put the car back together and sent it out on track. When it came back, the bit of steam had turned into a waterfall coming down over the bellhousing and our race weekend looked like it had come to an end.
