Exclamation Smoke from the exhaust!

Hi guys!
There is white, sometimes mixed with blue smoke going out from the exhaust!
And it's more goes out when I shoot the pedal gas down!
When I go slow, I don't see any smoke, but when I stop,
there is a freaking fog and smells terrible, also my exhaust tips are black, looks like an oil coating.
What do you think, guys? How to solve this problem, and who did?

Stock exhaust, no cats.

turbo seals are finished...turbos need to be replaced

Same thing happened to me when I went full catless.

As soon as they replaced the turbos, no more smoke.

I have all the same symptoms as you after going full catless. Turbo seals are gone time to upgrade!

Like the others mentioned, most likely turbo bearing seals are leaking oil in your turbos, causing the blueish smoke. Cats cover up the smoke, so it will become more pronounced when going catless. Have them inspected, most likely you will need them replaced. If out of warranty, give Rob Beck a PM

when going catless, this is one risk you have to take? If so, is there anything we can do to prevent the seals from going out before the downpipes are installed?

From my understanding the cats cover up the smoke which would hide this problem. Therefore going cats has no ill effect and would actually tell if your turbo are going bad?

your turbos can go if you are catless or catted, their presence has a debatable effect on the turbos longevity.

granted catless sounds better and reduces backpressure.

Whether you have cats or not has little bearing on the turbo seals, just the symptoms.

Soon will come the new turbos.
But what if it's not a turbo seals.
Could there be a problem in the valve cover, valve stem seals, pistons, or something else?
By the way, put the oil catch BMS, no difference, still smokes and burns oil so much, about 1 litre in 300-400 km.
What do you think?((( Why its so much oil going out??

You also may have an oil leak somewhere..what's the mileage on the car? Check the front of the engine, see if you can spot a leak coming down from the oil filter housing down the front of the engine block...oil filter housing gaskets are known to go on this and earlier bmws

85 000km.
I already changed the 2 gaskets on the oil filter, there was some leak...
But it didnt help!
And again, I have to add 1 litre per 300-400 km
such a number can not be due to external leakage

If that's the case check your valve stem seals and valve guides...its quite possibly them

Намекаешь на прокладку клапанной, или на трещину в ней??
Do you think that oil flows from the valve cover gasket or its crack in it?
