Re: Re: Can't get freeze plug fitted

Bud,
    I hate to differ with you--they are core plugs, NOT freeze plugs!  The 
block will crack from internal freezing LONG before a core plug will pop out 
of position.  Those holes were there to allow room for supports for the sand 
cores for the internal water passages during the casting process.  It's a 
very common misconception that they have a freeze-protection function.
