WHITE SMOKE FROM THE EXHAUST WHEN THE ENGINE IS COLD???

What causes white smoke from the exhaust when the engine is cold? The smoke smells like petrol, the spark plugs were fouled and not firing very well so I replaced all the plugs, this doesn't seem to have fixed it though.

The coolant level doesn't look like it's dropped and the oil and water do not look like they are mixing, it is very definitely a heavy white smoke (not blue or black) I don't think it is just a case of steam, there is enough white smoke under heavy acceleration when the engine is cold to smoke out an intersection. Yet once the engine has warmed up the problem totally goes away.

So what does it sound like guys? Weak spark? Over fueling? Dodgy PCV valve? Any help would be great :)

Very possibly oil being caught up in the splash-plate inside the rocker covers. I've heard it's common with the V6 engines.

heard that too. Need to remove the covers and drill a hole for oil to flow back out (or something simple like that) from behind the splash cover.

Thanks guys :) Ok, How will I know if "oil is being caught up in the splash-plate inside the rocker covers" ?

And if the oil is doing that how is it getting to the combustion chambers? positive crankcase ventilation system? And why is it doing it pretty much only when the engine is cold?

I know on the earlier models (1600cc) you can join two wires and get the trouble codes out of the computer, Does anyone know how to get the trouble codes on a 2000cc V6 model?
