Man I can't explain it any better
If you don't see the difference in my pic then you never will on your car.
I can see it from across the garage with the cams off, I see it instantly even with out the mirror. The mirror helps you view it at a better angle to confirm.

Also in my situation the tip of the valve broke off, and the valve was just sitting there, stuck open because the spring could no longer pull it back to close it, this guy drove home like this and parked it, even after that had a "mechanic" aka "idiot" start it up and rev it a little and it still did not drop that valve, extremely lucky. The cam lobe on that cylinder had started wiping out because of the hitting.

What is #11? And wouldn't this part keep everything together?
BTW, this pic is from a Honda engine, not necessarily an S2000 engine. Does ours differ from this?

As part of the check - would you also see grooves or wear marks on the cam lobes from striking the lowered valve stem - and possibly contacting the retainer?

MX-5, good explanation
To clarify a little more, the #11 split keepers a tab on the inside surface that engages the groove in the valve stem #6. When installed on the valve stem they form a tapered outside surface that engages a corresponding taper inside the retainer #9. The valve springs force these tapers together. To dissassemble, the retainer is pushed down against the valve spring, freeing the keepers. Often a knock with a hammer is needed to unseat the taper lock.
When the retainers split, it allows the taper of the keepers to pull thru.
What I don't understand is why the retainers split from the bottom... seems to me the higher stess from the taper lock is on the top surface?
