I just replaced the timing belt, water pump, idler pulley, tensioner pulley, and auto tensioner in my 2011 honda odyssey 3.5l. It starts really well, runs great, and drives great. No misfires, no skipping, no crazy vibrations.... BUT it idle I have this quiet sound coming from inside the timing cover. I made a really short video of it. It is SUPER easy to hear at the end where I stick my phones mic in the timing cover port. Should I be worried about this new subtle sound?! PLEASE HELP!!!! Video is here: https://youtu.be/tVHl4q2eGFo

By the way, you ROCK!!!! and I watch your stuff a TON! Someday, when I am down in Texas, I am taking you for lunch!

Sorry, I hit return and it just sent your name.... anyway. I took the pulley back to the store under warranty to be replaced. I even called Honda to get the proper torque for the new one, and guess what? The new pulley makes the EXACT same sound. So I am thinking perhaps this is just a sound these ones make. The grease seals could be making it on the pulley, or perhaps the bearings..... but either way, it gives me a bit more comfort knowing they all sound like that. Other than that, everything is working great! Thank you for the advice and heads up!

I ended up taking this apart again, and used an old transmission hose as a "stethoscope". Turned out it was the idler pulley. Which is unfortunate because it is brand new and came in the kit. So you were right on!!! I am returning this pulley for a replacement this afternoon, and hope to have better luck with the next one. BTW, I torqued this pulley to 33ft/lbs. Is this accurate? I just don't want to be the cause of the failure.

does sound a little like a worn bearing, something on one of pulleys, like an idler pulley bearing. if it gets worse over time I'd figure that one out
