RoD KnoCK new bearings?
okay. i just dropped a b16a in my 91 teg. it ran fine at first but throwing a code 22 due to a wiring problem. with that fixed and no codes present i drove to see if vtec would crossover. it didnt. so i checked oil again. its full. now i can hear a slight knock when i first start the car. it seems like after the motor gets oil pressure it kinda drops off and goes silent. but when i would rev just a little (like to 2500-3000rpm) i could hear a knock from the bottom-end. i am saying its a rod knock. it seems very slight at the moment and i am not going to drive it anymore.
1) how much damage do you think has been caused?
2) could i just put new bearings in it and if doesnt knock or seize up i am good right?
3) do you think i will need the crank reground?
any opinions greatly appreciated.

Your bottom end knocking doesnt have anything to do w/ vtec crossover (most likely), and if it is knocking you've spun a bearing and need to tear down the motor.
Check your TPS sensor/ground, MAP, coolant temp sensor, oil pressure sensor.. etc and if any of those are out of whack, vtec will not engage.

oh but it does. vtec runs off oil pressure. if a rod has spun or is knocking the clearences are loose which decreases oil pressure.

Yes but thats not where your pressure sensor is located. Time to order some bearings and tear that chit down.
