i have a b16 first gen and the bottom left head bolt the nut just spins. i'm not sure if it's the nut or the bolt and i need to remove it. Does anyone have any ideas on what i should do??

the head bolts are all stock. i can take off the valve cover because it just spins i cant take it off to see if it's the nut or the bolt the spins.
