Emma Johnson asked 5 months ago
I recently had an oil change done on my 2011 Toyota Sienna, and soon after, I started hearing a ticking sound coming from the engine. This noise was not present before the oil change. I'm concerned about what this sound might indicate and whether it's related to the oil change or something else.

Hi there, Emma! It sounds like you're dealing with a common post-oil change issue. Engine ticking noises can be alarming, but there are several possible explanations for why you might be hearing this:
  1. Incorrect Oil Grade: If the oil used isn't the correct viscosity for your Sienna, it might not be providing adequate lubrication, leading to ticking sounds. Toyota Siennas typically use 0W-20 oil. Double-check the oil grade used during your recent service.
  2. Oil Filter Issue: Some aftermarket oil filters might not be compatible with your vehicle, causing abnormal sounds. It's worth checking if the right filter was used.
  3. Dry Start: This occurs when the engine is started without proper lubrication, potentially due to a delay in oil circulation. This could have happened during the oil change process.
  4. Mechanical Damage: There's a possibility of minor damage during the oil change, such as bending a metal baffle under the oil cap. This can happen if the service technician wasn’t careful.
Given these possibilities, it's advisable to:
  • Verify the oil type and level.
  • Inspect the oil filter for compatibility.
  • Consider redoing the oil change with the correct specifications, especially if you're unsure about the service quality.
Lastly, if the issue persists after these checks, a visit to a trusted mechanic for a thorough inspection is recommended. It's always better to be safe and ensure your vehicle is in top condition. Hope that helps! Zack - Motor Verso Mechanics Team
