Lots of white smoke on idle

[ZRZ]

Hello all,

I'm getting a hell of a lot of white smoke from the exhaust on idle when the car is warm, increase a lot when revving slightly but no smoke when moving. Smoke smells very rich but I'm not sure what this could mean? Any help?

Petrol or diesel? Any bad running?

Petrol and running completely fine on idle and while moving. Nothing seems different at all. Has a decat system if that should make a difference?

Decat usually makes abit more smoke/steam

This doesn't seem like a little bit of condensation smoke or anything. It's like a continuous smoke cloud that stinks of petrol.

Oil seeping past the thrust bearings in the turbo. When on idle there is not enough pressure to keep the bearing sealed. Apparently. I had the same issue and ended up replacing the turbo which fixed the issue. The decat reduces the back pressure making the seal worse...
