Installed the above, along with the T Storm stuff this winter. Today Is the first miles on, since those mods. From Valve covers to catch can, to breather over rear tire. After about 50 mi stopped for lunch, went back out and there's some sort of ick on my rear tire, turns out the breather is dripping, what looks like oil/water mix, creamy white,oily. I open drain on catch can, and maybe half cup of same stuff runs out. The oil in oil tank looks fine. The bike is not overfilled, it may be under, but not over. So what is happening , anyone? |

Oil/Water mix. Normal. Exacerbated if you start your bike in the Winter months. Unless you take your S2 on a long ride, you will continue to get this. Kinda of looks like White Lithium Grease. |

Yep that's what it looks like. Bike was never started, during winter. Started first time last week, with fresh oil. Are you saying I can expect this every time I go for a short ride, forever? |

If the oil in the tank is not cloudy with moisture and its only milky coming out of the breather tube, then the hot vented engine oil must be mixing with water condensation inside the catch can before exiting the tube. Along with the normal condensation inside the engine as it warms up venting out the breather. If thats the case then you aren't risking any engine damage. As Two Seasons said, taking it on a long ride to allow all the condensation to evaporate should clear things up. Its the same as driving your car short distances and the exhaust system sweats and you end up with water in the muffler and pipes. Driving it 20 miles or more will allow all the water to evaporate and dry out your exhaust system so the pipes don't rust out so quickly. Driving or riding short distances and not allowing the normal condensation inside any engine to evaporate is a lot harder on an engine than driving it long distances where everything can dry out. Continuous short distance riding or driving will sludge an engine up, although modern oils minimize it a lot better than oils did 25 years ago. |

I hope that's it. I did about 50 mi today. Are you supposed to use the umbrella valves with the XB set up? |

With the XB rocker box cover you eliminate the middle spacer and the umbrella valve. |

That's what I thought, just checking see if I screwed up. |

Just curious, is your rear PCV rubbing the gas bladder? That happens occasionally on S2s. Unrelated to your post; others covered that well. Condensation build up being evaporated out. It's normal, not just in winter, but in very humid, rainy conditions as well. |

Phelan, re PCV, yes it did, so I'm running two front covers. I can make you an excellent deal on two rear covers, Hope you're all right, re the moisture. (Message edited by johnod on May 28, 2016) |

Weather doesn't make a lick of difference, it's the heat/cool cycle of the engine oil itself that causes spooge. If you don't ride the bike long enough to burn the condensation out of the oil, you're going to get the spooge. Air-cooled bikes do NOT have thermostats; they take longer to get up to temperature than a liquid-cooled motor. Like the charging system (ride it long enough to put juice back in the battery), I don't recommend "short hop" rides without either being OK with spooge, using a battery tender, or both. |

Keep in mind that two front covers puts the rear PCV lower than ideal position, so you will get a bit more oil blow by and a side effect. |

That's true, but I figure that would be pretty negligible. I could be wrong, just a guess. |

Some one on here did cut a pcv valve and lowered it a bit to have enough room under the fuel tank |

Ya I saw that. Took it out for another ride seems fine now. Must just have been residual condensation , as pointed out here. Thanks |

I, too, had a bit of contact between the PCV valve and the gas tank, so I used a valve cover that placed the PCV valve lower than it should be. This covers the air inlet with oil. It pumped oil constantly out of the vent tube and totally slimed the rear of the bike on my 75 MPH 62-mile commute to and from Orlando / Melbourne. Now I have a rubber spacer (VW oil cooler seal) under the tank mounting plate and both PCV valves properly positioned at the high points of the heads, and a 1250 kit from NRHS. No more slime. |
