  It's a schoolboy(or girl if you like) mistake, and not something anyone who works on these engines should ever allow themselves to do - cos you use the bolt to stop that happening, till you have it seated correctly.... 
 @ CaptainBoing - Well, there is that I guess.  We'll probably check the crank and big-end bearings while we're at it.  Knowing our luck, they will all be due for replacement.
 
 @ SimpleSafeName - They are small, but still too heavy to lift out by hand.
  You can't get into the bottom-end, without removing the gearbox that is basically the sump in these power units.  To seperate the gearbox/sump from the engine, you have to take the whole assembly out of the car.  Oh well - something to keep us busy at weekends for a while I guess... 
 I might post photos if anyone is interested.
