    "Core plugs" - they are an 'interferance' fit - they need to be drifted (knocked) into the hole with a shouldered dowl or similar tool that pushes against the edge lip only and not reach the bottom of the plug. A big hammer and a few knocks until the outer lip is flush or same as the others. Obviously you will need the correct size core plug and the surfaces need to be absolutely clean. Do not use any sealant. Surfaces can be smoothed with very fine emery paper if there are any rough spots.

    Good luck.

    so what you are saying if i can knock this core plug back in so its flush like the others then its good to go?

    Also what would of caused this core plug to pop out?
     
  5. Has the supplier been notified ?

    The plug can be reinserted,make a tool to evenly push it home.Some loctite paste can be used as a sealing agent then fully pressure test the hx before putting back into service.

    Why it came out ,there are many reasons :!:

    They all leak, usually the heads of the stainless bolts snap off when you undo them, the flow switch breaks into a hundred pieces and the return fitting siezes so solid even hulk couldn't smash it out!. You did well to get it swapped, is it fairly new?
