Does this happen when you have had the engine running for a while? Also what colour is the smoke & what does it smell of?
There is usually a little wiff of smoke/steam that comes out if the engine has been running for a while & is hot,say if you have been driving for at least 10 mins,then take the cap off.It should smell of hot oil and not anything else.

I know this may be a daft questuion but have you checked the oil level?
It may well be that the level is low,causing the oil that`s there to over heat,also did you put the correct grade oil in when you changed it?If it was too thin in viscosity this may be the cause.

I would suggest that there is some blockage in the crankcase breather pipework or in the pipe work that allows crankcase oil fumes to be sucked back into the inlet tract

this comes from the TIS disc but I don't know where the hose is on the actual engine

Remove the positive crankcase ventilation hose.
2Inspect the PCV hose for blockage.
lIs the PCV hose free from blockage?
Yes
CLEAN the PCV oil separator or INSTALL a new intake manifold as necessary. Test the system for normal operation.

No
CLEAN or INSTALL a new PCV hose as necessary. TEST the system for normal operation.

Hi all,
Nothing to worry about, all is normal.
This is called Blowby mist, Basically, where oil is subjected to high temps and alot of crankcase air movement you getan oil mist, which is more often than not fed straight into Inlet before the Turbo.
I work within Engine testing for Ford, we have a glass catch jar in this circuit and measure said Blowby, it helps determine Engine health ( if rings have had it or engine not bedded in, Blowby increases ).
When at full throttle at say anything above 2500 Rpm you cannot see through the Catch jar for the mist.
It usually does take a few hours to clear, dont worry!!!!

The mention of full throttle on a dyno takes me back (25 years about)to the time of a federal spec 4.2l Jag XK engine wide open at 4500 RPM and the whole of the exhaust glowing bright red

Was that the old XJ straight six whose name escapes me? Lovely engine, more English than roast dinner!
Not trying to out do you but....
Focus RS engine fitted with full vehicle exhaust which is fully lagged Cat backwards singing at 6500Rpm and the whole thing glowing a deep orange ( except turbo which is bright yellow! ), you can see the Catalyst bricks.
Currently working on a naturally aspirated 3 Cyl 1.0L petrol, variable Cams, direct injection and a whopping great torque wave of..... 100Nm...... not quite the same, sounds more like a sewing machine, but it cant do a cross stitch ( yet! )
