So basically I bought a previously tuned e92 with n54 and suposed 3k km turbos on it(almost brand new turbos). I test drove it no smoke no nothing. After buying the car i changed the oil. The last owner only used 300v motul 5-50 but i decided thats too much for my driving and went ravenol vst 5-40 which if you don't know much about oils is pretty reputable and scientifically proven oil! 2 days earlier(before the oil change) i got mhd and set the burbles to max agresive and longest duration(last owner didn't like it and never put it on). after 2 days i change the oil and maybe after 2 more the car starts smoking heavily under deceleration and making clouds on stop lights. so i change the valve cover with elring on and stop the burbles... 100km later everything is the same. Should i drive more? or maybe clean boost pipes? I'm waiting on the oil delivery to change it back to the one that last owner drove to see if it helps.
Sorry for long post and thanks in advance to anyone that could help!!!
