I was just quoted $10K to do a turn key swap on a K24 build by a reputable shop. That's not an option for me. Good news is same shop offers reconditioned short blocks.

You might be able to save this motor.
Low oil, especially with high rpms, the firs thing to suffer is usually the rod bearings. They wear excessively very quickly, and you end up with too much clearance for a film of oil to protect. As the big end rod clearance bangs around on each piston stroke, you get a knocking sound. You described a tick. If its not yet a knock, the right mechanic could still save it.
The procedure can be done with engine in car. Oil pan is removed. Rod is disconnected from crank. Crank journal is mic'ed for size, then carefully polished by hand. This work requires skill and experience. Not just any mechanic can do this with any success.
But if its done right, and new rod bearings of the correct size are carefully selected, with an eye for extreme detail, your motor can sing again. Maybe.
It all depends on how bad the crank has been damaged. And if you can find someone capable of this sort of work. And that understands the S motor and its somewhat unique bearings sized to clearances.
The most important thing to do now is not to try and start it anymore. That will just cause more damage.
Next is find someone that knows how to do this work. Note, chances are extremely low that the Honda Tech you mentioned is the man for this job. Dealer techs are trained to replace assemblies, not fix components. He's just gonna say you need a new motor.

That sounds like the "knocking" sound my car was making too. I'm glad you posted the video. The difference is my oil level was barely on the dipstick. It seems like the car will not consume oil, the go through it at a rapid rate. Possibly if I'm into VTEC more vs cruising around. Either way, my motor is now screwed because I wasn't diligent enough with the oil level.
