Exhaust fumes in cabin

[Llamapup]

Hello All

In an effort to locate the source of my slow oil leak I have removed my bottom engine cover. I have noticed as well that the rubber seal on the top engine door is now starting to completely dissintegrate.

Could either of these account for the smell of exhaust that I have recently noticed while driving?

Thanks

Chris
