Pistons play??

[Nik0las]

I recently start to update the engine changed the rods + all the other stanff that needs to be change - evirithing is new but kept the stock pistons and I met with a similar problem like this video http://www.youtube.com/watch?v=Z__bl1Y4Ecc

I'm pretty sure that the play is in the piston main bolt, because there is no play in the rods and crank it's self...

How bad is this? The play is not so big but you still can feel it. Can I drive like that

that looks normal to me. the rotation is that way, and that is needed for when it goes over TDC and back to the downstroke.

what you do NOT want is what i had.... axial play. this ended up all four wrist pins were broken. it lifted the head and hydrolock occured, and as we know water does not compress like air....
