What would someone suggest to fill a small hole in the side of a GT6 block I recieved a donor long block in very good shape good compression good oil pressure except for a small hole in a rear oil galley hence the donation the hole is where the aftermarket oil feed line runs from the back of the head to the port typically where the oil prssure piping go's into the block it looks as if someone has tryed to drill out the plug that go's into the side of the block and managed to drill out the threds I could drill and tap new threads but I would like to finish what the PO started and install a feed line included with the block
