Air intake elbow troubles

[gcoffelt]

Ever since I bought new replacement seal rings for the air intake elbow, it simply does not want to go on straight so the rings fit in properly. I'm aware it's a stupidly easy-functioning part, but it's not wanting to co-operate.

Also I noticed there is a thick coat of oil in the elbow, and a small puddle in the air intake box. I've completely cleaned these a few times, yet every time I open it back up they're coated again. Is there even supposed to be oil pooling up at the bottom of the box? It doesn't seem right to me.
