1992 honda accord

The bolt holding my harmonic balancer to the crank keeps coming loose.Any ideas why? I used an impact wrench during installation.Can any timing problems cause this? I’ve reinstalled it again using loctite,but am afraid to drive it. (4-cyl)

Try using a torque wrench instead of an impact wrench and get the bolt to the proper torque spec.
