The dealer who serviced my 2.2 did this thoughtless overtightning of torx bolts and repeated the same idiocy on our 147 undertray after a timing/balancer belt replacement.I overcame it by struggling for hours with long nose pliers,swearing a lot and finally using a large blade screwdriver between the underbody and the tray whilst turning the bolt under the pressure from the screwdriver.My next plan was to bin the undertray but fortunately the thread finally turned.Subsequently I copper greased the threads-only to lose a bolt and washer(on the 147) to vibration after a few thousand miles.
I have just serviced the 159 prior to an Italian trip.This time I have not overtightened the bolts and have used Hylomar on the threads to stop them dropping out.(I hope.)So large blade screwdriver behind the undertray may well be required again!
I wonder why the the brass captives aren't at least in a square hole?Mind you, I'm sure the dealer's "technicians"would find a way to round them off and set them spinning uselessly....
