Oil return line leaking

7 posts in this topic

I just started my bike today and oil began leaking from the oil return line coming out of the sump behind the gear shift lever. I went and bought a new o-ring, but it's still leaking...any ideas? My bike is a 2003 WR450

This is not a spot it would leak out if overfilled. Plus, I put in the exact amount of required oil. Any more ideas anybody?

Try two orings...    I have a 03 WR450 that had a leaking oil line and nothing stopped it until putting the second oring on it.

 

Been fine ever since.

I finally got around to working on my bike again. I put in a second o-ring and the damn leak stopped. I was very surprised!!
