I bet they didn't have the injector cups installed correctly. The other dealer will probably replace the injectors again or at least tear it down for injector replacement.

well odd thing is now it doesnt seem to be leaking at all could it have been whatever was left in the crankcase??

A very slight chance that they dealer didn't change the oil, but if they didn't you could go back on them for that. The TSB for the injectors tells them to change the oil, filter, and fuel filter.
