Isn't Lockteft the chinese copy of Loctite?

A freeze plug should have an interference fit, so no glue needed

^^^^ This! Whatever happened to the old one?

I would peronally not use Lochteft or other chinese loctite copies.
Loctite is very expensive, I know. But do your research on internet on the copies and you will gladly pay the price for loctite.

Again, no locktite or glue/adhesive of any kind.

Freeze plugs are strictly friction fit.

I am asking this because after around 15 Km the freeze plug has been fail again,
so new, I need reopen the engine ☹

when I install the freeze plug I had the good feeling that the freeze solid feed in….

Strange and fracking

Did you install a new plug? Or reused the old plug?
You need a new plug

I installed a new one,

the original freeze plug has been crushed so hard that I needed time to understand that behind the rocker there is missing freeze plug

so I started from water pump, than head gasket and finaly I understand that it is missing hidden freeze
