Symptoms & Diagnosis

Warning Signs Your Oil Pan Assembly is Failing

  • Oil leaks under the engine: This is the most common sign. Look for drips or puddles of oil where you park.
  • Low oil pressure warning light: This light comes on if the oil level is too low due to a leak, or if the oil pump can't pull oil correctly.
  • Engine noise: A rattling or knocking sound can happen if the engine isn't getting enough oil.
  • Burning oil smell: Oil leaking onto hot engine parts can cause a burning smell.
  • Visible damage to the oil pan: Dents, cracks, or rust can cause leaks.

How to Test if This Part is the Problem

  1. Check the oil level: Make sure the oil level is correct. If it's low, add oil and check for leaks.
  2. Inspect the oil pan: Look for cracks, dents, or rust. Pay close attention to the gasket area where the oil pan meets the engine.
  3. Check the oil pan drain plug: Make sure the drain plug is tight and the washer is in good condition.
  4. Pressure test: A mechanic can perform an oil pressure test to see if the oil pump is working correctly and if there are any leaks in the system.
  5. Dye test: A special dye can be added to the oil to help find leaks. A UV light is used to see where the dye is leaking from.

Common Failure Causes for This Part

  • Road debris: Hitting potholes or debris can damage the oil pan.
  • Corrosion: Rust can weaken the oil pan and cause leaks, especially in areas with road salt.
