So I've got this noise. It's most pronounced where I'm at in the video - rear of engine/front of trans. I was really hoping it was a cracked flexplate but it looks perfect. It sounds so "tinny" I thought for sure that's what it was, but I just don't see any signs of plate problems. It does it with the trans unbolted and slid back, although not as pronounced.
Some more details:
The noise comes as you quickly rev, or if you hold the engine in sort of a light load.
The truck was 3 quarts low on oil when it started doing this, around 5k after oil change.
Otherwise, it runs perfectly smooth and powerful.
Should I check for lash adjusters or anything else? Or is this loudness at the bottom most surely a bearing? How can I verify?
