On the bench, put 2 welch plugs back to back. Drill a hole through the centre of both. Drill one out to a clearance fit for a small bolt, and tap a thread in the other hole of the other plug.
Put the assembled 2 plugs into the hole in the engine and gently tighten the small bolt. As they flatten, the 2 plugs should work as intended.
