[SOLVED] What does this look like to you?

[wkreps]

What do you think happened here?

[tortoise]

can't imagine that they make these scooters so that they can't run WOT

Why tempt fate and significantly enhance the odds of piston blow-by venting excessive oil mist from the valve cover?

[Stig / Major Tom]

I get the same stuff , and I don't ever run WOT.
Empty it every week or two, or 6 (as I do).
Not sure what it is or where it comes from...but every scoot has this vent/drain hose it seems...and it is NOT a worry.
A veteran scooterista will chime in with where it comes from.

That's oil mixed with water mixed with gas mixed with ethanol. It's a nasty smelling blend for sure. Normal buildup, that hose separates the vented air from oil and gas for the PCV. If you let it build up too long it can spill into the airbox and dirty the filter.

After viewing Wayne's video I decided to check the tube on my scoot.  Nothing came out when I took off the plug, and looking at the tube it looked clean (it was a clear light pink).  Is this accumulation in the tube something that comes after a lot of usage (I have 750 miles on mine)?  Is lack of anything in this tube a problem?

B&L,
? PCV ? Positive Crankcase Valve ?
Is that the piece that all of the hoses come into at the front of the airbox? How does this valve get air (from crankcase vent, right?), gas (from where?) and oil (from where?) to that single point and what is the purpose?

I'm wondering if it stems from the original factory fill of gear oil. It is the only time I've had gear oil from the gear oil vent in the airbox. I know the liquid has been in there a long time (like maybe even since it was new) but I just got around to looking at it.

[BettinANDlosing]

Positive crankcase ventilation, oil eventually gets in the from the breather (basically an open tube from the valve cover, gas gets in there from carb kickback. The Brewster is designed to separate liquids from air and it ends up in a little sponge filter where that clear hose connects to the airbox. Over filed gear oil will end up in there too. Also, there shouldn't be much in there at 750 miles.

Yeah, I get the same stuff in mine from that drain tube. It's there just so the junk has a place to go so it doesn't end up cycling back into the engine. I open the plug and drain out the tiny bit of gunk each time I do my oil changes to keep it from backing up. No Prob!!

[de dee]

some one called it the puke tube,  I clean mine about 10,000 miles , the most i have seen in it is 1 "that was the first one, the last time was about 1/2 " at 25,000 miles,. 300i downtown

Thanks everybody. I certainly appreciate the knowledge sharing around here.

[MoToFaLcon]

Wondered what that mystery tube was myself. Now i know!! Its a garbage disposal lol!!   

[BettinANDlosing]

Does anyone know what the small tube or hose next to this one is? I have a lose hose that hangs right next to this one. It is black and as far as I can tell, nothing has come out of it. Ideas?

This is the drain hose for the carb bowl. Allows you to drain the gas out of the carb for the winter. Nothing should EVER come out of that unless you open the float bowl drain!!

Wayne,

How many miles were on your scooter when you checked the hose?

Wayne,

I'm not really sure but I not check it about every other oil change or just whenever I think about it. There's not been that much in there. As easy as laying a napkin on the garage floor and opening the hose end. Let it drain , cap back up and toss the napkin.
