my Toyota Camry XV40 (2007-2011) smells like burning oil what's causing it

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the engine is cool and parked on a level surface.
• Disconnect the negative battery terminal to avoid electrical issues.

2. Address Oil Leaks

1. Identify the Leak Source

   • Clean the engine area with a degreaser to remove oil residue.
   • Start the engine and let it run until warm, then inspect for new oil seepage.

2. Replace Gaskets/Seals

   • If leaks are found at gaskets (e.g., valve cover gasket), remove the old gasket and clean the mating surfaces.
   • Apply a new gasket and torque it to manufacturer specifications.

3. Check Oil Filter

   • If the oil filter is leaking, ensure it is properly tightened.
   • Replace the oil filter if it appears damaged or worn.

3. Replace Oil

1. Drain Old Oil

   • Place an oil pan under the oil pan and remove the drain plug. Allow oil to fully drain.

2. Install New Oil

   • Replace the drain plug with a new seal if necessary and torque to specification.
   • Add the appropriate type and amount of new oil through the oil filler cap.

4. Inspect PCV System

• Remove the PCV valve and check for clogs or damage.
• Clean or replace the valve as needed, ensuring proper airflow.

5. Final Assembly

• Reconnect the negative battery terminal.
• Start the engine and let it idle, checking for leaks and listening for unusual noises.
