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.
