The pictures were taken with a canon 20D D-SLR and a 50mm macro lens. It's quite a nice combination for this kind of photography, but the depth of field is so incredibly shallow that getting all important details in focus takes a bit of practice...

@tomkelley: The engine was a little over a year old, so it was used one season for racing. There was still plenty of compression and it ran fine, so my friend was rather disappointed about the premature death of the engine...

Exact same thing has happened to me on an old OS CZ-Z years and years ago... twice.

Those internal bearings need changing too! I have no idea why people don't change them more regularly. I do now for every 2 piston and sleeves I put through an engine. Then again, those were on those old engines, and I have no idea if it's justified on the newer ones.

Then again, apparently it is! Sorry to hear about the damage.

On the good news side of things, my old CZ-Z has worked flawlessly after each blow-up when a new piston/sleeve, conrod, and bearing was installed. I still have it running to this day (although not as my main engine).

Awesome photography I must say. Sad to see that the death of a ball bearing killed the rest of the internal components of the engine.

I dont think he was running too lean. If he was, the top of the piston would be black like it has happened to me. It was the combustion of when the pieces of the shattered ball were in between the piston and head button. Which is what created that horrendous surface.

No, it was the normal bearing that came with the engine.

The only real maintenance the engine had needed so far was a new conrod. Everything else was still in (near) perfect condition...

It was my engine that has gone into engine heaven

Some ppl said it was running too lean or something like that.
It was earlier too rich than too lean, it was just some practice run.
But i'm still a bit dissapointed that my main bearing went wrong

At least it died through no fault of your own so now you can get a new one, guilt free!

Ussually engines commit suicide when they feel unloved and neglected. When your next engine is born, make sure he is not neglected, otherwise I will have to report you to Engine Protective Service Agency. Your engine will be taken away, and will be placed on a foster home (my car hehe).

Maybe you took for granted. Maybe he was having girlfriend trouble. Perhaps it wanted a new shiny P/S set too, and the conrod was not enough.
