C5 Corvette knocking sound
I was doing some errands yesterday and i noticed that my car would shake when going from a stop, it kind of felt like it had a misfire, but the car showed no codes. Once i got home i noticed a knocking sound coming from underneath the car by the oil pan, definitely noticeable on idle but it seemed to go away when revved up. I’ve done an oil change in the past and the oil looked flaky so im maybe thinking my rods bearing are going out? Car is at 109k
Does anybody know what it might be?
Here’s a link to a video i took: https://youtu.be/0GIV6XkoBdI

Pull oil dipstick and wipe on clean paper towel, do you see the flakes you saw before.
Or remove oil filter and cut it open to see if any metal.
If no flakes or metal double check for exhaust leaks, start car while engine is cold and feel where exhaust manifolds bolt to main exhaust pipes for any sensation of leak.
Make sure “harmonic balancer” dampener is not wobbly.
The stethoscope sounds like a good idea as well.
I was able to hear and see the video.
