[COLOR="Green"]I have searched and read about the reroute of the crankcase vent on the 04WR. Some go in the airbox, some dont, some tried a pcv valve, some t off, oil fills the air box,sand gets in the motor,some put a filter on it
All these options made my head spin and I left mine alone
I sunk my bike yesterday and knowing what can happen after I finally got out, I pulled the dipstick and saw my motor was filled with water.Reading these forums has saved me a toasted WR(THANKS)
So, what is the cleanest way to run that vent? I dont want water or sand in my motor.I dont want my airbox filled with oil.
I rode my friends bike back to the truck, got a few quarts and a drain pain,(earth first !) flushed the motor 2x and finished the day and stayed out of the water.

Do other 4 strokes have this issue?

From my understanding the hose only sucks air when cranking the motor over so if you stall in water push it out before statring it again. :confused:

On the '05 and newer models, the factory routed the breather hose to the airbox. I'm sure they had good reason to do this. If I had an '04 or earlier bike, I'd do the same. Can't say as to how other 4 strokes handle this. My friends '04 (maybe '03) XR400 has the breather hose going back into the frame where the oil is held.
