Oliver Daniel Johnson asked 6 months ago
Hi, I recently had an oil change done on my 2011 Toyota Sienna. Following the service, I've noticed a ticking sound coming from the engine. This is new and wasn't present before the oil change. I'm concerned about what this noise could indicate, especially considering the recent oil change. Could it be related to the type of oil used or something else? I'd appreciate any insights or advice on how to address this issue.

Hey there, Oliver! It's quite common to encounter new sounds from your car after maintenance work like an oil change, and understanding the underlying cause is crucial - it could be nothing, or it could be pretty serious. Here's a breakdown of potential reasons for the ticking sound in your 2011 Toyota Sienna:
  1. Incorrect Oil Viscosity: If the oil used isn't the recommended 0W-20 grade, it could lead to inadequate lubrication or pressure in the engine, causing ticking sounds. This is especially true for engines with hydraulic lifters.
  2. Dry Start: The engine might have been started without oil momentarily, leading to temporary noise until lubrication was restored.
  3. Oil Filter Issues: The brand and type of oil filter used can impact engine noise. Some filters, especially low-quality ones, might not maintain proper oil pressure, causing the lifters to make noise.
  4. Damaged Components: Physical damage to parts under the oil cap, such as the baffles, during the oil change could create a ticking sound. This can happen if the equipment used during the oil change process inadvertently bends or damages internal parts.
  5. Other Factors: Less common issues might include leaks in the manifold or the presence of debris or old gunk loosened by the fresh oil, which might affect the valve train.
Recommended Actions:
  • Check the Oil Grade: Ensure the correct oil grade (0W-20) was used.
  • Inspect for Physical Damage: Look under the oil cap for any signs of physical damage or misalignment.
  • Oil Filter Quality: Verify the quality and type of oil filter installed.
  • Professional Inspection: If you're unsure or the noise persists, a professional inspection is recommended.
It's a good practice to address such issues promptly, as they can signify more significant problems if left unchecked. In case of any doubt, consult with a trusted mechanic or your dealership. Hope that helps :-) Zack - Motor Verso Mechanics Team
