Re: Core Plugs (Freeze Plugs)

The trick with any and all freeze plugs is to coat the backside that contacts water with a nice thin coat of black RTV silicone. I've done this on every engine I've worked on that I had to remove the freeze plugs. This seals them up, and resists corrosion. Also, I use brass freeze plugs exclusively. I've never had a problem with them, ever.
