So some will run without coolant for some time. Probably better to stay at a real high throttle setting once you know you're engines screwed. Run long enough in that state the rotor bearings will fail next. One failed will not stop the engine unless you close the throttle.
I doubt that there will be much power left to help, but a couple of feet may be enough.
 
Thanks muchly Lynn.  Leon had a very similar tale (replying from an different account that isn't on the list). 
 
Hey Ken, was your engine still running?  Sounds like it was.  Since we know that losing oil will seize the engine in short order, and since it sounds like losing water won't immediately take you out of action, I'd say losing oil is worse.  Again, I don't care about the engine, just getting to a good landing.   
 
Thanks,
Rusty (wondering what failure Ken hasn't had)

  Yes it was still running and I taxied in on it and it was pumping green smoke out the exhaust, its a tossup which is worst but I would say loosing water is worst as the damage was much worst and I only ran it at full power for less than a minute and what I would really worry about is a fire if you ran it any longer as it was hotter than the hubs of hell and I glided in with no power.
