At least he's able to afford the repair, I mean if you can buy a CGT :mrgreen:

LOL, read up you fool. :P

I also agree with sentradude, but i really thought that the engine of the CGT originally being developed as a race engine would have handled the over rev without a problem. I assume it's about 2k over the set rev limiter, now is it the limiter that hurts the valves?

The valves will be damaged by the pistons as at that increased engine speed the valve springs cannot return the valves fast enough (valve float) and hence you get valve piston collision, however in this case a camshaft also broke, so lots of other damage could have occured.
2k rpm over the rev limit is a significant overrev!!! Especially for such a highly strung engine as the CGT! (high compression = very close valve piston clearence, little margin for error) Impressive that the bottom end held up though, but you'd have thought they'd engineer in a little more safety factor in the bottom end than the top, valves springs etc are a damn sight cheaper than a block , crank, pistons, rods etc!!
