The oil pan holds the majority an engine's motor oil. If an oil pan is damaged, epoxy can be used to repair small cracks. The epoxy is a two-part repair that hardens around the damaged area to keep it from leaking. It also seals the inside of the damaged area on the oil pan. If the epoxy is not applied properly, the oil pan will continue to leak.

Instructions

  1. 1

    Park the vehicle on a safe work area and engage the parking brake.

  2. 2

    Jack up the front of the vehicle and place the jack stands under the designated front jack points on both sides. Slowly release the jack until the vehicle rests securely on top of the stands. Leave the jack in place.

  3. 3

    Locate the drain plug on the bottom of the oil pan, and position the dripping pan under the drain plug. Loosen and remove the drain plug with the 1/2-inch drive ratchet and a socket. After the oil has flowed from the pan, screw the drain plug into the oil pan and tighten with the ratchet and socket.

  4. 4

    Locate the damaged area on the oil pan. Wipe the damaged area with a clean rag. Brush the paint and oil off of the damaged area with the wire brush.

  5. 5

    Wipe the area with a clean rag. Sand the damaged area and an inch of the area surrounding it with 400-grit sandpaper.

  6. 6

    Wipe the area with a clean rag. Mix together the two-part epoxy as directed by the instructions on the package. As soon as the two-part epoxy is mixed, dab the plastic scraper onto the epoxy and apply a generous amount of the epoxy to the damaged area of the oil pan.

  7. 7

    Push the epoxy into the damaged area. Then, spread the epoxy all the way around the damaged area. Make sure to apply the epoxy in a 1-inch circle around the damaged area.

  8. 8

    Smooth the epoxy so that there is about 1/8-inch depth to the epoxy. Crawl from under the vehicle and let the epoxy harden as directed by the package instructions.

  9. 9

    Crawl under the vehicle and ensure the epoxy has hardened around the damaged area.

  10. 10

    Open the bonnet and fill the engine with motor oil. Crank the vehicle and let the engine run for about five minutes. Turn the engine off, and inspect the repaired area on the oil pan for leaks. If the repaired area is leak-free, jack up the vehicle and remove the jack stands. Lower the vehicle to the ground and remove the jack.

Tips and warnings

  • If the damaged area is not properly clean and smooth, the two epoxy will not stick to the surface.
  • The two-part epoxy is made up of a filler and a hardener. If the epoxy is not mixed properly, it will not seal the damaged area properly.
  • Be sure to apply the epoxy soon after mixing together. The epoxy actually begins the hardening process soon after it has been mixed.
  • Keep a constant check on the repaired area to ensure that the epoxy is holding.
  • You can purchase a two-part epoxy sealant at most all auto parts stores.
  • Use extreme caution when working around a vehicle that is on jack stands.
