No offense, but I think part of the issue is your lack of mechanical knowledge and buying a car with a rebuilt engine. Now your relying on others to tell you if there is an issue when there may not even be one. To me that last video sounds like loud valves or something top end related I hear zero rod knock. Post a video of it being reved to 3k and held for a moment and then blipped to 3k and let off a few times. If there is still no rod knock sounds my suggestion is to drive it for 1-2k miles change the oil and send it to Blackstone for $25. If there is a problem in the build you will get elevated Aluminum. If you get normal results then focus on the valve adjustment, to me it sounds very much like loose valves. Heck check your exhaust manifold to make sure you don't have a leak at the head or a leak at the cat. Do not pay people any more $ until you do these things!

i wasn't trying to be hard on him, I was trying to help and provide perspective, hence my use of "no offense". I think what I said is a valuable perspective that should be entertained before spending more $, but your right he can do whatever. If he wants to pay $250 for someone to look at his oil with a black light then ok....
I still advise going on the S2000 Cincinnati Facebook page and getting a shop reccomendation if the OP wants to go further down the rabbit hole

can you do a UOA, if for nothing else, for informational purposes? it's only $25 I believe.
you don't need to be a tech to own a s2000. but i guess the question would be, when you test drove the car before you bought it, did you hear the noise at that time?
has the oil level ever been low?
at this point, we are just trying to pinpoint the source of the noise because of the possibility that the bottom end might be okay.
whatever you decide to do, hope you keep us updated.

In case anyone is still curious on the status of the car, I just dropped the oil pan today and am going to also pull the cylinder head. The second shops' diagnosis that the noise seems to originate from cylinder #4 has been making more sense to me as I listened to it more, and considering the engine was initially rebuilt for piston drag in cylinder #4, I wouldn't be surprised if the noise is coming from there. Plan to start by pulling piston #4 and looking for damage.

Any flakes or things like that in the oil pan? How does the #4 rod bearings look?
