yfz Constant oil leak

[mrking1988]

So the other day i was changing my oil, when i noticed by the oil drane plug on the block there was what looked like, a oil return line comming out of the block. Well it was a little oily, didn't think much of it, just tightened it up and that was it. Now it leaks more and faster with the fresh oil, anyone have any ideas on this or have had the same problem?

You need to change the crush washer thats behind the line fitting .

is the crush washer, like a one time use design? also is a yamaha specialtry or can you get it any hardware store.

Sorry i was worng it is a o-ring not a crush washer . You will have to get one at the Yamaha shop. PART# 93210-10197-00

i pulled the line earlyer today and it was the o-ring like you said. But it look perfectly fine to me, could it be shot, but not noticable looking at it? not sure what to do here

I would change it . Sometimes they look ok and they are bad besides they caint cost that much . :D

Mine kept doing the same thing. I would replace it and it wouldnt leak for a couple of weeks, then drip drip drip.

I put 2 O rings in there and my skid plate has been dry now for several months...:)
