I may have got lucky i guess it depends on how big the crack was how much you cut and the engine. I have ran the motor and i cant tell anything ever happened i even think i have more bottom end too. Not sure who but i seen someones modding work and they too shave the piston up some. I would say mine is 3-4mm from the conrod pin.

This situation has been just waiting to happen to me. I came from OS's which don't have a slot, just a flat spot on the back plate and never had to even think about putting the piston at TDC. Now I run Nova which has the slot. I saw a guy pull his apart at the track and chipped the piston this way. The Novas I have run, I only removed the cooling heads to change from standard to turbo button. Had I needed to remove the back plate, I would have did the samething before my enlightening. Rest assured, your mistake may help someone else.

Engine manufacturers need to put "TDC" in big red letters on the backplate.

Sounds like most companies are rebuilding the engine anyway, it might save them a few bucks!

i went back to where i bought the engine and they called alpha about it becuase they werent aware of it either, so alpha put new piston and sleeve in it for nothing as they claimed it under warranty. But the reaon it come under warranty was becuase it did not come with instructions, which they now have in thier engines haha, oh well good for me and i guess this well let everyone no what not to do.

cheers
