Hello everyone! I am new to the forum. I just picked up a 2004 Accent with a 1.6l DOHC and 5 speed transaxle 186,000 miles. Car is clean and runs great but has a rattle when the cold, it goes away completely once warm. You can hear it mostly when the RPMs are falling. Here's a video: https://youtu.be/vnzysfPJ0Q8

The car has new timing belt, new Sparks plugs and wires. I just changed the oil to mobile 1 5-30 with a wix oil filter. I'm hoping this noise is just the HLAs (lifters). I am waiting for my stethoscope in the mail at the moment to help pinpoint the location. Can anyone confirm my suspicions? Or give any advice on anything else to look at?
