No they shouldn't be that loose. Torqueing a bolt is to put a higher load
on it then the load it sees in service.
It wasn't torqued to begin with or something else has changed..

I would check all the cylinder holdown nuts and thru-bolts before I flew it
again.

Lyc or TCm has a service bltn explaining how to measure the rotating
resistance of the engine by using a spring scale on the prop. Take a
measurement then torque the thru bolts then take another measurement.
A significant change is signs of bearing pinch.

Good luck and hope for the best.
