suggestiosn for chasing down and oil leak

[gormleyflyer2002]

i had oil leaking from my belly pan on yesterdays ride, sled was never on its side all day. made it home but lost a decent amount of oil, no warning lights or anything.

i rode across a big lake with about 12" of pow..(70km) I noticed this oil when we stopped to change a blown belt.

any suggestions before I start tearing into it tonight....?

thanks, brian

Could the oil have been there from another time, but only leaked out this trip. (was the sled on her side on a previous ride)

I'm thinking the fine powder getting inside your belly pan and freezing, expanding the belly pan enough to allow the existing oil to leak out. Otherwise, I'm thinking the powder froze and created ice perhaps causing a pinch or crack the line.

I guess it could also be from the filter. (loose filter, o-ring failure, base drain plug). The fact that its coming from the belly pan sounds like something close to the filter.

Keep us up to date on your findings.

Have you recently changed your oil filter.

I have heard of the old O ring coming off the old filter so that you have two O rings together when you put on the new filter, leading to leaks.

Take it for what it's worth. My mechanical skills rate about a 5 out of 10.

Mine leaks oil from the airbox that runs down the front of the engine, breather from the oil tank vents into the airbox. I put a screen over the outlet on the oil tank than slipped the hose back on seems to help.

1st.
that was it......mine has been clean and dry for almost 4k and now this.

what kind of screen did you use....?maybe explain in a little more detail.

any idea why it might have done this, it wasn't on its side at all. Got stuck once and it was maybe 45' deg towards the oil tank side for a minute or so. Lots of drift jumping etc...?

LOL.....better than what I was dreading.

thanks btw.

It's a nylon screen for a door or window, I wrappped it around the oil tank outlet and reinstalled the hose. Seems to help with the splashing into the airbox.
