Re: Help please - R6 - White/creamy substance in engine...
It is likely just condensation in the engine that vaporizes with the heat, then mixes with a small amount of the oil and adheres to the oil cap where it recondenses. Its probably not a big deal if the engine is still running and acting as it should. Keep checking the oil at the dipstick or sightglass for a while and if the condition persists of gets worse, you likely have a blown headgasket, at which point it will begin to consume coolant. If that is the case, it would belong before the thing wont run right, and then not start. Just keep checking your levels of coolant and condition of the oil and you should be fine. If it does get worse though, deal with it, dont ride it till it blows.
