my Cadillac Escalade T1XX (2021-Present) smells like burning oil what should I do

Symptoms

• Burning oil smell inside or outside the vehicle
• Possible smoke or vapor from the engine bay
• Oil on the ground or undercarriage of the vehicle
• Check engine light illuminated (if applicable)
• Decreased engine performance or unusual noises

Diagnostic Steps

1. Inspect the engine bay for visible oil leaks or oil residue.
2. Check the oil level using the dipstick to determine if it is low.
3. Look for signs of burning oil on hot engine components (e.g., exhaust manifold).
4. Scan for error codes using an OBD-II scanner to identify any related issues.
5. Examine the oil filter and oil drain plug for proper installation and potential leaks.

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery for safety.

2. Inspect and Clean

• Inspect for Leaks:
  • Use a flashlight to check for oil leaks around the engine, oil pan, and gaskets.
  • Clean any oil residue with a degreaser to identify the source of the leak.

3. Replace Oil Filter and Oil

• Tools Required:
  • Oil filter wrench
  • Socket set
  • Oil catch pan
  • Funnel
• Steps:
  1. Place an oil catch pan under the oil pan.
  2. Remove the oil drain plug and allow the old oil to drain completely.
  3. Replace the oil filter using the oil filter wrench; ensure the old O-ring is removed.
  4. Install a new oil filter with a light coating of new oil on the O-ring.
  5. Replace the oil drain plug and torque to manufacturer specifications (typically around 18-25 lb-ft).
  6. Refill the engine with the appropriate grade of oil (refer to the owner's manual, commonly 5W-30 synthetic).

4. Test for Leaks

• Start the engine and let it run for a few minutes.
• Inspect the oil filter and drain plug for any signs of leaking oil.
