Holset Turbo Charger coolant leak

[bham78]

My Holset Turbo charger appears to be leaking coolant from the center section on the back side of the turbo. There appear to be 3 cup plugs pressed into the housing. One of these appears to be the source of the leak.

I know common sense says pop em out and pound new ones in. But I dont want to make a $3000 mistake.

Any info would be a help at this point.
