Freeze plug issues

It didn't leave the factory dribbling so the machining was probably fine. Pull the replacement, fish out and pull the first leaky one, then take some emery paper and make sure there is no rust ridge or crap on the bore. Use a mirror or your finger to verify there's no groove from an idiot using a chisel to remove the OEM one. If it's all flat, and bare iron, clean the bore off with brake clean, and use a small amount of sealer of your choice (I use Ultra Grey, Black, or Red silicone) and drive the 3rd one in. Make sure it's in far enough. Even with deep design plugs the bevel around the outer edge should be visible.
