Clouds of white smoke when idling?

[TomTomTom]

Hi guys my car seems to randomly kick out clouds of white smoke when I come to a stop and sit at idle. Any ideas what could be causing this?

It currently has a 2.5" intercooler setup
3" decat exhaust
N112 Bypass
N249 Bypass
EVAP + SAI delete
Ko3s
Stage 2 custom map
Oil catch can
N75 J valve
Coldside DV relocation

The fault seemed to appear since fitting the 2.5" setup + oil catch can + J valve + DV relocation.

I have currently got no fault codes having recently swapped the MAF + Pre cat lambda over.

Any idea why its pouring out this smoke on idle? I am assuming its measuring an intake of more air than it really is and so injecting fuel to compensate and over-fueling at idle?

Any help appreciated!
Tom.

nope.
excess fuel is black smoke.

white is either coolant (would smell sweet if its running antifreeze) or neat oil unburnt into exhaust from likely cause turbo

unless you have cocked up somehow the breather system when doing the catch can install?

would oil make blue smoke ?

My coolant doesn't appear to be going down tho and oil will be blue smoke... It only happens on occasion at idle not every time but is more often now, I had one thought, when I did the engine swap I notice a crack in the hot side and the turbo to downpipe gasket has been re-used many time and I previously had the faults codes for lambda/maf with high input signal. So could the crack be causing the lambda to read the car as being to Lean and pumping more fuel in?

The oil catch can is plumbed in correctly I'm sure
