Urgent ! Is it an oil evaporation??? please help

[bmn]

I have an intriguing question.

When the engine is hot,and then you turn it off,and you open the oil's gap on the engine (the one where you add oil into your engine)....is it normal to see Evaporation??????


I own a 320i 1995 Bmw.

Do you mean as in steam/smoke for a little while??

[bmn]

Exactly.

Of course the steam will stop as soon as the engine gets cooler.

IS this normal to see?

it's been over 2500 km since i changed the oil

[marti5]

Dont panic! thats just how it should be, if you took a shower at between 92 and 120 degrees Im sure you would have steam comming from your head!!!LOL

As for an oil change I do mine every 10,000 KM's

Aha,

thanks !

Do you have a pail gunk around the top of the filler? If yes then the steam you mention could be water, This points to water in the oil, normally via head gaskit failier. If no pail gunk then no probs. The engine has a breather pipe that takes the bulk of the oil vapour which is drawn through the cold air inlet and burnt in the cylinders whilst the engine is running.
