I friend has a '99 Escort TD which has split the outlet hose from the turbo to the intercooler, he can't get it replaced for a couple of days. It's obviously down on power and noisy but will he do any damage if he drives it for, say, 400 miles? I seem to remember tales of running a turbo without a load is liable to have it spinning too fast but that may just be me getting old.
Cheers
John
