I've just done a little bit of research, I thought the engine serial number had a date identifier, but apparently not.
The engine numbers are sequential.
However, the first F20C2 would be:
F20C21000001
not
F20C20000001

I'm really keen to understand these numbers, so that we can get a chronological list...

mine never actually failed, it just made a knocking noise
Even with the Block out of the car they could not find anything visually wrong (no crank end float, no scored bores, no swarf in the sump)
so they just sent it back to Honda without ever knowing what was wrong with it.

What were the insides of the main and big end bearing shells like?

I do not know if this is true but I was told (by somebody in Honda cutomer services) that the oil pump in late model s2000 is slightly smaller than earlier models and is the reason for these faailures, this could be nonesense but then again it could be true.

The oil pump changed sometime in 2003.
Part numbers are:
15100-PCX-013 (1999-2003)
15100-PCX-023 (2003-2009)
I doubt this has anything to do with late model engine failures.

The oil pump was faulty on my 06 engine.
It wasn't able to produce sufficient oil pressure a low revs which damaged the little end bearings.
At low revs when the oil was fully hot you could hear the little ends rattling. But when the revs were higher the oil pump produced enough oil pressure to float the little end bearings and you couldn't hear the rattle.
Honda technical seemed to be aware that the oil pump might be at fault as it was the second thing they told the dealer to replace (after the TCT).
However, by this point the little ends were too damaged and had allowed the pistons to float and pick up slightly in the bore.

Definately should not get any rattling in vtec, I would visit Honda to get it checked out. From what it would seem there is no tell tale warning signs of the engine going but it would seem that any untoward noise can be heard by holding the engine rpms at about 2500 and gently revving it up and down to 3000 rpm, do this in neutral and with the engine fully warmed up, it may be an idea to get someone else to rev it whilst you listen under the bonnet, if you can hear a light knocking then it's new engine time!
