Oil Out of Vent Hose

8 posts in this topic

After i run my bike, some oil drips out of the head vent hose that runs down to the frame. The oil is a white milky color, does this mean that i have water in the engine, i have never drove in water, i did wash it with a power washer. Well i need to take the engine apart? :banghead:

open up the oil filler cap and see if the oil is cloudy.

If it is, you have big problems (blown gasket).

If it is not, don't worry about it.

cloudy oil does NOT necesarilly mean blown gasket.

a sufficient amount of water in the air intake will cloud the oil, blown gasket or not.

My thoughts is that while power washing, his airbox got a nice puddle of water in the bottom...that got sucked in when he started the bike.

also, you may need to change the oil a few times to get all of the water out of the system....

some people recommend flushing the oil system with Diesel fuel...i have never done it, nor can i recommend it...just a recommendation that i have heard.

i know your all going to flinch,but....honda makes a drain tube for the xr600's that is a one way valve(lets water out but not in) $6,it replaces that clear sealed tube under the airbox(that does nothing i can tell) and holds on with a hose clamp :banghead::banghead: this eliminates water build up of anykind

This is very common. I would be willing to bet that you will find your oil to be fine and have no problems.

This is usually due to condensation in the tube. Unless you flip the bike and directly hose water into the vent you are not going to get water in there.

If you pay attention I would bet you will see this come and go depending on humidity and several other things.

If you take a look at your oil and it is not milky, you have no problems..

My 400, 426 and my 450 have done this and there has never been a problem.

Keep in mind that the vent tube pulls air in and out, and the air coming out will be warm and cause any moister that may be in the cool out side air to condensate on the inside of the tube. That said, the out goin air will also contain a small amount of suspended oil that will mix with this condensation and cause it to look milky. As more and more builds up it will run down the vent tube and drip on the ground and look like a problem.

You did not due this with a pressure washer unless you directly shot water up the tube...
