Just rebuilt an old vspec with new crankshaf, new conrod, new piston and sleeve. New bearings too. After assemble I got some play between the rod and the crankshaft pin, when piston is on top (TDC). Just stucks on top and makes to much play at that point.
Is this normal?? Is there something I miss on rebuilt?

You're not feeling "play". You're feeling the "over the center" snap that the engine has. Please see our FAQ on this:
