Are there any sealers that will work on a very small leak on a freeze plug without using block sealer or removing the soft plug?

If you are looking for permanent fix, forget it. You can get rubber screw in for a temp fix, the best way is to replace it.

I ran a SBC for 12 years and never heard of a soft plug and have been through plenty of engine projects ? Got to be a freeze plug!

pretty easy to install but dont think about using those at the track!
screw in are the best.

I always learned to pin the plugs and use a bit of indian shellac sealer on them .

definitley replace the plug with a brass plug and put a good coat of permatex on the backside before installation/ Just my $.02

Frost plugs are freeze plugs are soft plugs. Depends on how old you are and where you are from. Install them w/ an epoxy or JB and they wont leak. Also use brass ones and they won't ever rust through. That's important I guess if you can get a block to live a bazillion passes.
