Why does my engine smell of burning rubber after an oil top up?

I have a chrysler neon LE R Reg 1997, 2.0L SOHC. I topped up the oil level last night (when it was a howling gale!) The wind blew some oil over the engine block (I wiped up what I could get too). Afterwards I started the engine and could smell burning rubber type of smell and saw smoke coming from the back left of my engine bay. Can anyone help me URGENTLY, please?
