can i do rings and valve seals on my 93 honda civic DX with 121,000 miles on it, with out taking out the motor? and is that something i can do myself.....i'm not a mech. but i changed a motor in my 72 cutlass when i was a kid, i'm very mech. inclined...it burns a little oil, and i would like to make it last and maybe run a little better.....thanks
