Default What is this knocking/tapping?

My car is a 2005 with 75k miles. I noticed it last night when I got home. It was fine when I left the gas station so it must have happened on the ride home? My car is not low on oil and I just had a valve adjustment done in March.

I will attach two videos. One from last night when I noticed it and one from just now on a cold start with giving it a tiny bit of gas.

I'm pulling the oil pan tomorrow. Is there a way to check the rod bearings? I have heard of people replacing them by just removing the oil pan.

Yes you can replace them from the bottom end.

I would keep digging to find that noise before putting more money into it.
