fail safe way to seal freeze plugs

[wurley]

Is there any methods to seal up my freeze plugs so I dont have to worry about it?

What products are good?

I filled it up with coolant before putting the motor in and almost every single plug was seeping out coolant on a fresh built motor.

Theres a very viscous non-hardening sealer sometimes used on freezeplugs. Youll have to start over with new freezeplugs though, and make sure youre pressing them in evenly

Use that and get new freeze plugs...
