I need to sand the inside of the down tube to positively confirm I am not also collecting combustible fuel.

Indeed, you can eliminate the oil separator, and route the crankcase vent directly to the air box. However, all the contaminants being collected by the oil separator will then stay in the crankcase, diluting, and contaminating the engine oil. The used motor oil I collect is always in excellent condition, so I am very pleased with the design of the oil separator installed on the RX3. In addition to removing the contaminants from the engine oil, I also like to be able to inspect the nature of the contaminants being expelled from the crankcase.

If it is normal for the down tube to collect gasoline, that doesn't bother me. I am genuinely interested to know whether or not this is normal. If it is normal, I'm glad the fuel is being removed from the crankcase, instead of remaining inside to dilute and contaminate the engine oil.

Sand the molding seams off of the plug so it will positively seal in the clear plastic tube. I also put a light coating of silicon (dielectric) great around the plug to insure a good seal.
I haven't tried to burn any of the fluid but it smells so strongly of gas that I have little doubt what it is. And as said right now I've drilled a small hole in the plug it simply drains away. Though I would like to find a better solution, not a huge fan of dripping gasoline on back roads or anywhere for that matter. |

You realize through heat and pressure you can create kerosene/diesel then gasoline in the refinement process. If in fact the engineers are saying it's impossible for fuel to enter that line, but what is going into that line is combustable, then the engine oil is clearly being refined to a certain extent during regular driving.
I'll bet you can drain off that "fuel" and it's basically good enough to run a small R/C car motor. |

So I changed my oil today and I'd swear that it's diluted by fuel.
I change all my bikes and cars and truck oil myself and I know oil vicosities and my oil came out like water. Someone on this forum had a Fuel Injection dribble as I remember but how does it get into the crankcase ?and could this be related to the excessive fuel in the separator tube ? The plot thickens or thins in my case. I wonder if Detours notices a very thin,almost watery oil when he drains his oil ? |

I'm sorry to say I am not surprised. Katflap in the U.K. had fuel in his motor oil. Something is not right with your engine. My used motor oil is always in excellent condition.

I noticed Joe said it could happen if you overfill the oil. I'll recheck the level with the proper procedure, but I sincerely doubt that's the issue unless the 1.7L spec is wrong. I carefully measured 1.7L (not quarts) of refill oil after completely draining from the plug and all 3 filter holes. I know some oil remains, but not much if you drain it warm and tilt the bike both ways, so I really doubt that's it.

I am just assuming fuel is thinning my oil because what else would ?
It actually did not smell of fuel and it did not light. If it is fuel in my crankcase I am at a loss as to how it could get there. The only path that I'm aware of for fuel to get in the crankcase is by the piston rings but that isn't happening because I'm getting 60-65 mpg and my plug looks fine. |

The specification is 1.7 quarts, not liters. I fill my engine with 1.7 quarts, which is 1 quart, plus 22 ounces. This amount of oil fills the sight glass perfectly when you measure the oil level using the proper method.

So I am ok with a fuel like substance collecting in the tube and chalk it up to a particular trait with this engine/injection high revving engine.But I am still perplexed by the thinning of my oil and so I will drain it in a few hundred miles again to see if it is still going on.The fella in England had a similar problem as me and went as far as to change the injector but it made no difference. If there is a fuel dribble happening after engine shutoff maybe it is in the controller(ECU).Of course if it were bad enough you could risk a liquid lock condition.Checked my gas mileage this morning and I'm getting 65 mpg.It will be interesting to see what my oil looks like here after a few hundred miles. |

You could send an oil sample to one of those testing labs for absolute confirmation of fuel in your oil.
Out of curiosity can you get a sample of your oil to flash over if you hold a flame to it? / |

It has to be fuel that is thinning it,if it were water or coolant I would see a milky substance. I noticed that Joe at CSC has just posted on the blog explaining the venting issue as explained to him by the factory. |
