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!
