This doesn't pertain to my honda, but i came across a car who's plugs need to be changed. Upon removing 2 plug wires, I notice the hex nuts are rounded out. Cylinders 3 and 4 aren't rounded out and came out with a 5/8" socket. What can I do for the other two plugs that have no hex nut? tia

 

are u positive they are rounded out?when i pulled off my spark plug wires,the little rubber peice that is around the plastc end,stayed on the spark plug so i wasnt able to get the socket around it,it felt rounded,i then had to dig out the rubber.if they are rounded,maybe take off the head and go at it from the other side

 

thats exactly what happened. figured that out couple minutes after i posted. everything is a-ok. thanks
