What Causes Oil Stains on the Engine?
1 Answers
Oil stains on the engine are generally normal, but if it's due to oil leakage, then it's abnormal. The reasons for oil traces around the engine include a poorly sealed fuel cap or spilled oil not being wiped clean. Poorly sealed fuel cap: This may be caused by aging or damaged seals leading to oil leakage or seepage. It is recommended to replace the seal to enhance the fuel cap's sealing. Spilled oil not wiped clean: When adding oil, spills around the filler port that aren't thoroughly wiped clean can cause stains. Simply cleaning the oil stains on the engine will suffice. Cleaning oil stains on the engine: Purchase a bottle of all-purpose cleaner or engine external oil stain remover to quickly remove accumulated oil stains. Precautions during cleaning: Ensure the machine is stopped and cooled before use; cover distributors, electrical parts, carburetors, and air intake systems to prevent short circuits from exposed electrical conductors. Be cautious with all wiring and electrical induction parts inside the cover to minimize issues caused by water cleaning; shake the cleaner well before spraying onto the dry machine, then immediately wipe off excess spray with a damp cloth to avoid wax removal or streaking; let the cleaner sit for 5 minutes after spraying; after completing the task, start the machine and leave it in neutral for 5-10 minutes to ensure complete drying, then rinse with clean water.
