Oh the joys of watercooled turbos...
They work great....until one of the coolant lines cracks from heat exposure.
I was on my way home from dinner lastnight and all was well. Until i stopped to talk to some friends. One of them noticed a strong smell of coolant coming from my car. I hadn't noticed, but just to be safe, i got out and opened the hood. Well, i found that my overflow tank was almost empty
So when I got home, i started poking around and found that the coolant line thats between the turbo and the block was soaked
It only took me 2hrs to figure out how to get that done. At first i tried to get the banjo bolt..but that didn't work. Then i tried using a open end wrench. That was useless... I couldn't get any leverage. I got smart and went for the hose clamp that wsa holding the hose to the barbed fitting on the turbo. Bingo. The end had split. So I cut it off, peeled back all the heat wrap and then used a spark plug cable heat shield sleeve to cover the coolant hose for even better protection then the wrap that was on it.
Now it's all good again.

It must have been weeping for a long time. Your car has always had a coolant smell to it; every time I saw it I commented. It's possible that the hose had failed in a manner that allowed enough coolant to escape to smell without failing enough to allow coolant to be seen.

Braided lines FTW! It seemed like everyother wee one of the water lines would leak. Finally I said **** it and replaced both with braided lines.

braided lines still have plastic/rubber in them...
you need reflective sleeves or you're wasting your time. if the lines aren't physically touching the exhaust housing, they're not getting much conducted heat.
another option is the long-**** banjo bolts that somebody was selling.

maybe... but my coolant level hadn't moved since i bought the car and trust me..everytime i open the hood (a lot) i check the coolant level. It only dropped in the couple days before the major failure. I'll keep an eye on it the next few days. Sometime soon, i'll replace the lines completely and do better heat shielding.
Oh, when i took the car for a test drive i smelled coolant. When i got back to the house we found the leak and fixed it before coming back to Ga.... IIRC it might have been the same hose. I guess the repair was "eh".

right click on his image...
and i'm gonna reiterate about having a shiny reflective surface on the outside. if you dont protect against RADIANT heat, you're wasting your time.
lets take the sun as an example. big insulator (vacuum of space) between it and us and it still burns your skin.

i sprung a leak in a coolant line for the turbo on my sr20det... ended up it was so close to the firewall that i found it was easier to pull the motor up a foot or 2 than try and squeeze back there........ managed to do it all in one high school day. (skipped every class)
i miss high school
