In this video, we learn how to weld an oil pan. Make sure you are wearing protective gear on your face before you do this. Take your welder to your oil pan, then start to weld it while you are underneath it or you have the car pushed up all the way. Place a patch for welding over the part of the oil pan that is leaking. After this, use your welder to connect the patch together with the pan. This ill take several minutes to weld together, and when you are done you can let this cool and fill your car back up with oil.
