Here’s some pics of a custom drain plug we machined for an ATV quad fourwheeler. Someone tried repairing the drain plug threads in the engine by installing a Time-Sert thread repair insert into the engine but it did not seal and continued to leak. So we removed the Time-Sert and made a new drain plug with the same threads as the outside threads of the Time-Sert. We installed an o-ring on our new plug and the thread repair insert is eliminated and the plugs seals like a factory piece.
