Oil Level Window mystery - Any one help?

this one's cheaper, I could get one for you - but it will be a month -



Monsterparts billet oil cap

Had this on my 2V 900.  No problem.  Oil seems fine.

  Air has water in it. Tanks and crankcases breathe air, they get hot, they get cold. Condensation. Fix the "problem", by taking the bike for a good ride, use the gearbox and give it a rev. Any water will disappear. Burnt to vapour by the hot oil, then, shout it an oil and filter change, just in case you need to feel confident about it. Crankcase dilution of a type. Low k bikes rarely ridden often show this effect. At various times any sight glass equipped machine may show this oil/water vapour. Yes, if you blow a headgasket in a water cooled one, you'll "milk" the oil, but it won't be a happy chappy and you'll know there's something really wrong etc. All is well. Aunty Mal

Well have taken the Monster out for a couple of rides and made sure I warmed it up well and truly before going.  I am sure the neighbours enjoyed the S4R - Termignoni sound at 6.45 am this morning.  The "white stuff" has almost gone so with another longish ride this afternoon and tomorrow am I am sure it will be all gone.  Must get myself a new oil filler cap as the plastic one is a bit cheap!!!

Thanks for all your help and advice.

i rode to work almost every day back before 'the crash', and during the winter of '98 i think it was (maybe '99) i was riding my sport 1100i guzzi.  i changed the oil around june or so and about 1,500km later it was white - completely white like it was water cooled and had coolant getting into the oil, but not frothy.  it just wasn't getting hot enough on the 12km run to work (half on freeway) and i remember we had lots of fog that was so thick i'd be wet when i got to work.  plus they have a breather system that causes white froth inside the rocker covers under the same and even milder conditions.

if it's a 4v motor and has a leak from the back of the water pump it'll have milkshake oil.  we've had a few of them over the years - '99 or '00 996 mainly from memory.  head gaskets leaking coolant into the oil i've never seen.

Back from a long ride and the oil window is as clear as clear.....giddy up.

Yeah but the most fun you will have fixing a problem

My oil window was the same - cloudy. Changed the oil and still cloudy. A few long rides and it got better but still a bit cloudy.
I put a workshop light up close to get the site glass nice and warm for 1/2 hour and now its all good.

My Guzzi would do the same thing in winter. Big twins suck in alot of air through the crankcase ventilation and if it damp it shows up milky/cloudy in the oil.

Reading up on the K&N crankcase filter for the Duc and amomgst other things it said that the original breather can cause the creamy sight glass situation??

Interesting!! concept

I guess it could be sucking cold moist air through the Airbox ??

Here is a Fleabay ad for a K&N crankcase vent kit with the pros of the setup. 

Any opinions on the thing Brad  ??
