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.

  • FreedMike I’d like to say I’m outraged and won’t buy anything from GM, but aside from a Stingray or a CT5 V Blackwing, they don’t make a damn thing I want anyway.
  • FreedMike Well, given that the plastic “wrap,” featuring any number of colors ranging from off-the-wall to utterly obnoxious, is now a thing, maybe these guys figured they’d get a piece of the action.
  • SCE to AUX Hyundai still gives 3 years of Bluelink for free, then it's $99/year after that. I like it, and I pay for it.I agree that GM is just finding a way to raise prices, but what happens after 3 years - does OnStar disappear?This isn't different from other moves by mfrs. For instance, many drop the FWD option and standardize on AWD, while raising prices $1500. Few people complain about that.
  • KevinB I have three vehicles with OnStar solely for the purpose of accident response. Everything else they offer is useless to me because Bluetooth pairs my phone and car for hands free calls, Android Auto pairs with my newest car just fine, and if my car gets stolen, I don't ever want to see it again. The monthly diagnostics report in my email are also a good thing, but roadside service is a joke. My older cars, however, will cease operating by the end of the year because 2g/3g will go away. GM has no plans to retrofit an upgrade to these cars. It makes me wonder how many subscriptions they will be losing because of this.
  • Matt Posky A lot of dune buggies aren't street legal and plenty that are aren't really fit for any kind of sustained highway driving.Unless you live in a state where it's pretty much wide open for vehicle mods and the cops don't care how wild your ride looks, you're probably towing it to its play space. While the Manx should be street legal and capable of making it to the dunes without outside help -- arguably part of its appeal vs other options -- it's hard to assume a majority of owners won't still opt to drag it behind their pickup or SUV.
