Very well put! That's the exact same info I got from my conversations with 4 different MINI service people, one major independent BMW/MINI shop in Carolina and the MIN Guru himself Way at Way Motor Works. Who, for the record, isn't impressed with the R56 motor at all.

Overall recommendations:

Change oil VERY frequently
Check oil A LOT
use GREAT GAS, not good gas, never mediocre gas
Oil Catch Cans will help.
Techron fuel additives

On a "it may help/it may not": Seafoam.
Again, for the record, MINI Guru Way is not a fan of Seafoam either. I plan on asking him why at the Dragon this year. I know, I shouldda asked when I had him on the phone for 20 minutes.

Here's what I know as of now. And sorry I do. ALL, repeat ALL, R56 Cooper S's will do this. Seems there is something on the was the oil vapors recirculate back into the motors. What us old guy used to refer to as the PCV valve.


what about removing the pcv system and installing a cool looking breather filter. was having similar problem on my 2008 cobalt. the o2 sensor was getting stuck reading lean. did a cold air intake and when i did it i just put on a breather filter and it kind of fixed itself besides the breathers are only like 9 dollars from advance and look really good. just a thought.

Per the link I posted earlier in this thread, the dual-PCV system ties directly into the turbo.  The 2011 models have done away with one of them.  I guess you could do a breather and block off the PCV connections.  You would need to make sure no oily residue leaks out of it.

since the pcv recirculation line enters the intake before the turbo is it possible that that particular design was implemented to lubricate the turbine in the turbo? could eliminating that cause premature turbo failure? this has me super worried because i just bought a 07 mcs turbo this tuesday, knew i should have gone with the 04 jcw.

The two hoses are from two cylinders each of recirculated gases.  It would probably be poor to assume a turbo would be lubricated by them.  There is no way to guarantee any oil would be mixed in.  Per this diagram at RealOEM, the turbo has its own lubrication tube (#6).

Best advice is to change your oil every 5K miles or so.  Get with the dealership, or your preferred Eurosport shop, and have the engine get a carbon buildup cleaning.  Some members here are getting oil catch cans installed in their R55/R56/R57s.  While this will not eliminate the carbon buildup in the turbo, it will cut it down.

The two hoses are actually used at different times in the boost cycle.  one under boost and the other under normal operation.  Talking to BSH on the issue I asked if I should just go all out and put a catch can on each line.  They suggested that this was not necessary and that by blocking one of the PCV lines and putting the catch can on the main line, I could take care of the issue completely with less added equipment.  The nice part of that is I now have a port directly into the intake that is at a vacuum when not under boost for adding Seafoam to clean the valves.  I used the BSH Catch Can with the BSH dual boost tap kit.  It includes a plug so that you still can get the benefit of the taps but block of PCV gasses from going into the intake.  It then forces all PCV gasses to go to the catch can and back thru the turbo.
