Hi mate welcome to the forums. And if I do say so myself you found the best place to join for your 1st time :)
And as for the problem I've heard nothing myself either. And have no idea what the course would be to make that happen. I'm interested to what they say it is. I'm not trying to scare you but might be just a problem car. My Dad had a Granada Scorpio many year ago, and that had a problem of burning oil quick and smoking really badly even though it was a new car. Ford had there top engineers on it, my Dad went through 26 other cars that ford had to give him while they tried to sort it from, Maverick escort soft top and my favourite of them all the Probe 3.0ltr V6 :) I can't remember the total time they had the car but they did everything inc a full engine swap and it still had the same problem In the end I think they gave him the newer full extra pack ford sierra sapphire.
