Shot a picture of the welding magnet modified to hold a piece of smashed copper pipe. Works great provided the hole you are trying fill is flat and in a place that has enough area for the magnet to grab. Note that I had to grind a bit of the magnet frame so the copper is flush with the edge of the magnet frame.

The 5.3 looks like a pretty big engine when all the sheetmetal is removed.
