Help needed ! RS6 C6 Smoke at start up problem

[moustafaseddik]

Hey Guys, Hope all is well.

First time to write here. but i had a problem since the last oil change the car used to smoke before at start up but very minor. every time i start the car now it is a smoking massively once the oil reach the 100C level it stops. i though about the valves at start. but this will be a massive work especially i am in UAE and there are less good mechanics here. also went to different mechanics and did not get any logical answer as i know the car well. some say it might be a piston ring and some say might be something in the oil sump, I have one bad turbo or this model at least always have one leaking turbo which is the right bank. that being said it is been leaking oil from now and then and by every time i change oil i always clean the intercooler. I am thinking to add an oil additive for valve seals and see if that will help at least temporarily till i have enough budget to take the engine out. what you guys think ?

If its only after you changed the oil then that should be your starting point. Did you use exactly the same grade oil? Check the oil level, you could have too much oil in there now causing excessive pressure.
