I wondered when it would happen. The nipple broke off of my reservoir today and it happenend while I was driving so steam came rolling out of my car. I got on it and rolled into my driveway, smoking like a black dragon. While it did look cool, it ain't cool. Thank the gods I have a spare but I'll still be looking to convert it over to another, more durable one. Either way it sucks, so I think now will be a good time to upgrade my intercooler since it was pressing down on the nipple that broke.
Ahhh, fixed it, no problem. That was probably the easiest thing I've done so far. Now I've just got to rotate it like Matt did in his write-up. Thanks Matt, if you're still around.
