Hello anybody. I am so glad I saw this thread. While crawling around underneath mine today checking things out, I noticed this pesky drip of oil coming out of the tube next to sump plug, as shown above.
I popped onto the forum to find out, which is how I ended up here. After reading this, I went back outside to check the filter out, and it was a little loose, hence the drip.
It is now tightened back up. Cheers to the above folk.
