There is oil pooled up on top of the plugs and they sit down in the valve covers so there are seals in the valve covers around the plug holes I think that must be leaking. The oil is all over the threads and all over the ends as well so I'm thinking it must be seeping down through the spark plug holes. However, the gas smell in the oil makes it seem like there must be bad rings letting gas and oil go where it shouldn't. I don't know if the oil could be coming through the cylinder and up through the spark plugs to get on top of them. Probably both. I think the engine is the 3.2 but I'm not sure how to tell. The chilton shows pictures for the 3.2 that don't look like mine. For one thing, the chilton shows coil packs on each spark plug and I have the 3 side by side coil packs up front with wires to the plugs.

Does anything have to be removed to change the sparks plugs?
