why does my Toyota Camry XV50 have a smell of burning oil

Solution

1. Preparation

• Gather tools and materials: clean rags, socket set, oil filter wrench, replacement gaskets/seals, engine oil, and a torque wrench.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the negative battery cable to prevent electrical shorts.

2. Address Oil Leaks

1. Identify Source of Leak
   • Clean the engine with engine degreaser.
   • Start the engine and observe for oil leaks.
2. Replace Gaskets/Seals
   • If the valve cover gasket is leaking, unbolt the valve cover, replace the gasket, and re-torque to manufacturer specifications (typically 7-10 ft-lbs).
   • For oil pan leaks, drain the oil, remove the oil pan, replace the gasket, and re-torque the bolts to specification (typically 10-15 ft-lbs).

3. Oil Change

1. Drain Old Oil
   • Place an oil catch pan under the oil pan, remove the oil drain plug, and allow oil to drain completely.
2. Replace Oil Filter
   • Use an oil filter wrench to remove the old filter; apply a thin layer of oil to the rubber gasket of the new filter and install it.
3. Add New Oil
   • Replace the oil drain plug and refill the engine with the correct type and amount of oil (typically 5W-20 or 0W-20, check the owner’s manual).

4. Inspect PCV System

1. Check PCV Valve
   • Locate the PCV valve, disconnect it, and inspect for clogs or damage. Replace if necessary.
2. Clean or Replace Hoses
   • Inspect all hoses connected to the PCV system for cracks or blockages and replace as needed.
