I just had a google and you may be lucky that it didn't start as the outcome would have been possibly a broken crank if it happened while the engine was running.
What is it with Land Rover and oil pumps? TD5 bolt falls out,TDV6 bracket breaks. Perhaps they should fire their oil pump designer.LOL

Maybe this is what happened with the bloke a few weeks ago who had the crank break the first day he bought it.
