Lawn Mower Oil Leak Repair
Lawn Mower Oil Leak Repair. As a lawn mower engine ages, the engine block sidewalls weaken.

As a lawn mower engine ages, the engine block sidewalls weaken. If your lawn mower's oil level keeps falling and the mower is not smoking while running--which would indicate the piston rings are bad and it is burning oil--then this is a sign you have an oil leak. You can easily find the leak and fix it with a few supplies.
Things You'll Need
Rags
Cold-weld compound (such as JB Weld or Holts Gun Gum Paste)
Paper plate
Toothpicks
Locate the oil leak on your lawn mower. This is usually fairly easy, as the crack or pin hole in your engine block will have oil around it.
Tip the lawn mower so the crack is facing up. This will prevent any more oil from leaking out.
Buff the cracked area dry with a rag.
Read and follow the instructions for the use of your cold-weld compound of choice. Stir the cold-weld compounds together with toothpicks to create a quarter-size pile at a time. Make more as needed.
Scrape the mixture onto the crack. Spread it out with the toothpick and have it cover a centimeter away from each side of the crack. Allow it to dry for 12 hours or as specified on the cold-weld compound's instructions.
