Angry white smoke

Hi
I have a 2.8 coupe, engine code AAH. I'm no mechanic, so I'm after some advice.
There's a lot of white smoke on tick-over, yet oil & coolant levels seem OK.
Could anything else be causing this?
I've changed the oil and added valve additive, as the car had been stood for some time.
Any help would be appreciated.

When you say "white smoke" do you mean literally white smoke which is completely different to steam. Which are you referring to?

Hi
Thanks for your reply.
Like I say, I'm no mechanic, but I would say it's a smoke, that varies in density. Even when I've driven the car a fair distance, as soon as you leave it on tick-over, the smoke re-appears. Could it be it just needs a really good run?
Cheers

What your describing sounds the opposite to what i would expect especially at this time of year with these engines.It's normal for them to have steam wafting out but not normal what your describing. Why don't you try putting a cold plates against this white smoke and see if it condensates,if yes it's condensation from steam if not then sound like it could be oil burning.

Unburnt fuel if you're burning diesel in it. head gaskets are made of cheese on these, but hope not, any steam cleaned spark plugs?

Hmmm. just a quick observation, not knowing much about V6 2.8's but a reasonable amount about 20vT5pots, is it anything to do with the positive crankcase ventilation?

Only white SMOKE i have ever had from a car was unburnt fuel, it just gradually got worse until the problem was fixed, ended up looking like fog behind the car on the motoway

Auto trans fluid and anti freeze give off white smoke when burned inside an engine I believe.
