So to update, I have changed the red boost pipe. Obviously no real change and can still see some oil seepage?? I must not have tightened the jubilee clip up properly...will check.
More significant though, I have ordered a vortex style breather to see if that reduces the amount of oil passing through...I stand corrected from a few posts above where I stated whoever said it was an empty box is wrong...I have now realised that the red diaphragm is on ALL types of breathers on the "air" side. The changes are on the other side where it is in fact empty on the E90s. Hence going to a vortex insert type...
Lets see!!

On a lighter and less boring subject, I have just ordered the Bilstein B12 Pro Kit, all associated mounts and all front M3 control arms. Excited!
