tire 10 Report post Posted March 26, 2010 In the process of replacing my sump gasket I noticed part of this long thin spring poking out of the back of the crank (see green circle). I gave it a gentle pull, as you do, and it came out. WTF is it? Car is a 325i touring automatic, with a SA m20b25 motor. Thanks.. Quote Share this post Link to post Share on other sites
e30ftw 410 Report post Posted March 26, 2010 (edited) It goes around the front / rear crank seal (it's apart of it) whichever end that was. If you pulled that out you should replace the seal.. Edited March 26, 2010 by e30ftw Quote Share this post Link to post Share on other sites
tire 10 Report post Posted March 26, 2010 Aha, that makes sense. Good thing I have a new rear main seal here ready to go Quote Share this post Link to post Share on other sites
