smokey on startup

[franknapoli1]

hi all,
i have an 01 4.4i x5 with 194k and drives like a dream.
only this morning has it developed alot of white smoke from the exhaust on a cold startup. it would last 3-5 seconds and then stop. the x drives fine with no missing or reduction in power. when driving there is no smoke, and when warm, there is no smoke.
the smoke has a strong petrol/oil smell to it, but dissapears in a few seconds. im hoping its nothing too serious. any ideas??

any help would be greatly appreciated as i was planning on going for a weekend holiday with x this weekend??
thanks in advance
