@A330-300. Why would you say that there was an issue with an engine of the aircraft in YQX and then say that it's most likely not related? You shouldn't even suggest it. I am 100% certain that EI engineers wouldn't put any passengers, crew or aircraft in the air if there was a question mark over any technical issue of any sort. They've one of the best reputations out there. Your moniker and location would suggest that you either work for Aer Lingus or you would like to. Show a small bit more respect for your colleagues.
