2001 SV 650 S 36.000Km - water in the oil/ creamy substance

Hi guys,

I need your help! What things could be at fault when there is a creamy substance (probably water-oil suspension) under the lid where you fill in the oil, as well as small droplets of clear water found under it? I am suspecting a seal near the waterpump and hoping very much it won't be the head gasket!

Are there any known conditions to cause these symptoms?

Cheers and thanks in advance,

This is usually caused by improper crank ventilation . Check the small vacuum line that runs into the breather box and follow it back to the engine . There should be a pcv valve there it may be plugged and need to be replaced.If the breather filter is plugged this can also cause poor crank ventilation . Its not likely the head gasket as it would be a more noticeable problem , it would cause the oil to turn to what would look like chocolate milk, you would also notice a performance drop as well as overheating of the engine.

I had this problem aswell, it was after I bought a bike that had been stood for a while. Had me worried. I was told it would disappear after a few runs. Which it did.
