Sadly its not likely to be an injector, its more likely to be a compression problem. White smelly smoke shows diesel is getting into the cylinder but its not firing.
I can't think of any diesel people I know but I was recently recommended to use Peter Jones (Argyle Street South, Birkenhead) from the boss of another garage. The only other I would think of would be Birkenhead Engine Centre in Brook Street who I have talked with about my diesel.
