      The flywheel bolts aren't torque to yield types. If they were the tightening sequence would be an initial torque and turning the bolt through an angle. Best practice is to use new bolts, but they can be re-used. If reusing the bolts thread sealant must be used.
      The car makes it possible, but the driver makes it happen.

        Yes there one time use. Don't be cheap. Get new bolts.

            I have put together a LOT of motors and always reuse the flywheel bolts along with red loctite.
