What????? That is the worst possible thing you could have done!!! The piston rings need load on them to be seated! For 45mins all you did was wear down the walls with no load against the wall. Now that the grit on the walls is gone, there is no way to achieve a good seal again without getting the motor rehoned.
EDIT: Unless of course, the motor was plateau honed...
