So I'm in my driveway doing final adjustments to my idle speed, double-checking the rotrex belt tension, and overall just doing the "does everything check out" engine bay scan. I wiggle the coolant bypass hose that runs from the mixing manifold to the bottom of the water neck opposite the throttle, and it starts leaking. The hose has failed and generated pinhole leaks underneath the spring clamp.

Random shiite like this scares the poop out of me. At least it was in my driveway and I can roll it into drydock for repair.

This is a common issue when hose clamps are too tight. The center of the clamp bites into the hose and deteriorates over time. There are clamps that are smooth where they contact the host and I'll be swapping those in soon enough to avoid this.

Never mind... Your situation was a bit different. Maybe just due to really old hose and the spring clamp corroding?

Spring clamp isn't corroded. I'm pretty sure this hose is only 2 years old, I did hoses two years ago when I did the timing belt.

No one local seems to have it so I'm ordering one + a spare. I'm just really glad this didn't happen next month at an autox or on track. Probably would have killed the motor.

Well hopefully you would have shut it down before it overheated.

I forget, is this a track only car? If so you can get rid if all that crap, and should be running a reroute regardless.

No, it's still got everything. PS/AC/ABS. It will remain a street car. If/when I can have a track only car with the support logistics gear that requires, that will be another car.
