Hello All,

Glad to be part of a new forum and forgive me if this thread already exists (I couldnt find it). I have searched all over for thoughts on doing a seafoam treatment to my 2015 R56 (I think its the b46 engine at around 40k). I see the two PCV valves and I can feel the suction coming from the smaller of the two. But I just want to be sure I am not doing anything wrong by the motor. Does anyone with experience on this year/make/model have any wisdom. Should I do it? If yes, which pcv hose, bigger or smaller?

Thanks so much and glad to be here.

 

Lots of threads on NAM about using seafoam. The consensus seems to be that it doesn't help much..
