My friend called me up today after pulling his motor for a rebuild. He went ahead and installed his rings/pistons and new bearings.
He has never built a dsm engine before, Only Chevy's.
Well he wanted me to come take a look at his new engine, He has JE Pistons / eagle rods and some off brand ring setup.
I noticed something about his motor, Before he had his crank put in, I Couldrock the pistons side to side in the bore, I Would push down on the left or right of the piston and it would sort of "Rock" in the bore.
What would cause this? I'm assuming piston-wall clearances are not correct. Is this normal without a crank installed? I Do not remember my pistons doing this, But i was also very very anal about my clearances.
