ianwh4 Posted 5 hours ago Share Posted 5 hours ago My 2009 BMW E91 LCI, which belongs to my wife, needs a new overflow oil line. Could someone please tell me what it is and how it relates to something I can't seem to locate? Could you please? Quote Link to comment Share on other sites More sharing options...

Paqngo Posted 5 hours ago Share Posted 5 hours ago By "overflow oil line," do you mean a specific engine? Quote Link to comment Share on other sites More sharing options...
ianwh4 Posted 5 hours ago Author Share Posted 5 hours ago M57N2 and the fuel return line that extends from the injector's upper end. Quote Link to comment Share on other sites More sharing options...
Paqngo Posted 5 hours ago Share Posted 5 hours ago I believe the M57 goes from 6 to 1 on the HP pump, then from 1 back to pipe, though I haven't played with one in a while. Turn off the intake manifold job so you can see it clearly. Quote Link to comment Share on other sites More sharing options...
