I don't think it's the rod bearing on the crank.. A failing/spun bearing usually has a constant knock.

Oil is at the top "X," with roughly 4.75 to 5 quarts of oil.

The world needs more people like you lol.

Rod bearing noise is mostly heard when you hold the revs over 2,500rpm. Also if it was a crank bearing, you would hear it even without de-activating a cylinder. For all we know it could be fixed with something as simple as a valve adjustment. Worst case scenario you have mild rod knock which isn't the end of the world. I say inspect the valves which is much easier to do than dropping the oil pan, and go from there. In fact re-listening to your original video you probably have a ridiculously loose valve, probably one of the intake ones.

That's what I was thinking. If it was a rod or crank bearing it would have still been knocking even if u took the coil off.

rod bearing will stop if you remove the corresponding coil. Or at least reduce the noise considerably.

If you have a spun bearing, you will hear a few VERY distinct knocks, 3-6 of them, at cold startup.

Obviously there are some people here who know more than I do but the sound doesn't sound that out of the ordinary IMO.

Slowcrash_101

Would excessive clearance from bearing wear make the same noise?

is the car your DD? If not just drop the oil pan and take a look. Or send an oil sample in.

StrokerSi

No severe knocks on startup. In fact, you can't hear any knocking until the car idles back down.

It is not, luckily. I will do both those things when I have a free weekend.

If u have a magnetic oil drain plug u could check there ass well.
