i pulled my plugs the other day to check gap and i noticed the plugs were filled with oil. im assuming it is the pistons rings, but im not sure. im definitly holding off on nitrous until i figure out the problem. any suggestions on what else it could be?

Valve guides could cause the same problem. Usually if it's large amounts of oil it's rings. If the car spits out a small cloud of oil smoke at startup, it's guides. If it continuously spits it out, it's rings.

it only doe sit at startup or when i give it a decent amount of gas. its not a constant smoke. how do i change the valve guides?

The heads have to be removed from the car and a machine or engine shop has to drill the old ones out and put new ones in.
