Hey fellers,
I have a light knocking or ticking sound at idle that sounds like a light main knocking in any other vehicle. Had the dealer listen at last oil change and they compared it to another '14 runner and they said it was the backup fuel or oil pump (can't remember).

I'm not an idiot when it comes to mechanics but it would be hard to believe she's knocking in the engine somewhere. It's not a spark knock and doesn't knock during acceleration/when under load like a main knock. She's been serviced under warranty since we bought her new in '13.

What are your thoughts and has anyone experienced this? I'd like to do a sound bite but not sure I can on the forum...

Thx all
