2005 freelander - sporadic exhaust smoke

Evening All

Took my freelander off road last weekend , nothing to challenging more wet , muddy farm tracks.
It performed perfectly and generally runs really well.
However, half way through the day I noticed a lot of smoke coming from the exhaust , the car was not labouring and running perfectly fine. It then went away , I got out revved the engine and nothing, no smoke. I drove around for another half an hour then the smoke came back for about 15 seconds then went again.
What would cause this , I would say by the colour of the smoke it's more oil than fuel.
It was a cold day , the engine has the crank case breather upgrade (BMW) and a EGR Blank on it , the car runs really well , circa 98k on the clock.

Any idea what could cause it ?

this happened with my 320d bmw i found out it was a sticking cam follower lifter tappet this allowed the diesel not to burn from time to time
but it i have also been told that a leaking turbo or excesses oil in the turbo pipe could cause sporadic smoking

Stick some injector cleaner through it. This sorts this type of problem most of the time.
If that doesn't work, let us know.

Is your crank case filter clean
