does anybody know of a trusted engine fitter?? basically the bottom end of mine has took a dump. had new fuel pump, injectors, belts and ac. done under 5k ago, so a bit gutted that it's broke. long and short, I need to find someone who can repair it or supply, remove and exchange bare unit. which ever makes best sense. I'm in Norfolk, don't mind a bit of travelling.
thanks for reading.
any advice would helpful.
