Hi guys,
I contacted Honda and explained the situation to them and it turns out that the mechanic wasnt lying about the cost.
Honda told me that the crankshaft does cost 1400 for my car and that they are really rare to locate in this country specially as my integra in a Japanese import.
It seems he had a change of heart as he now has charged me half the price for the job.
I am baffeled by the sudden change but Im not compaining and am assuming its because I went to trading standards.
As much as I love my car, considering all the bad luck I have had I think I might just put it up for sale now.
Thanks again to you all
