Milky oil glass

[Seanp]

My oil glass is milky white I also had some just inside the oil cap ,
I have done an engine flush through it then put fresh oil and new oil filter did it as recomended the glass was clear after this but after a run the glass is milky again .it runs at normal temperature n rides n sounds as it should and the coolant is holding at its level so I'm assuming that its not leaking .
Has anybody had the same issue
Now my local Suzuki dealer are adamant its condensation 
I had an sv650 for a few yrs before this v-strom n never had an issue like this on that bike or any of my other bikes although I did get some white gunk out of the missus guzzi a few yrs back n the guzzi lads said that was condensation.

  Common thing this, a good long ride will cook it off and clear it, it is condensation.

Done 162 miles on it today n around 100 yesterday n its still there so wll have to get out further next weekend

Milky spy hole.

What you see is sludge, a combination of oil and condens.
My L3 650 had the same problem and I have tried a lot of things to solve this. When the outside temperature is above 15 degrees Celcius the sludge will disappear.

A few years ago I made a topic off this with some pictures in the Dutch V-Strom forum. https://forum.v-strom.nl/viewtopic.php?f=5&t=13429&p=195878&hilit=luchtfilter#p195878

The main problem is that the oil temperature is not high enough when it is cold outside.
Via the crankcase vent, condens collects in the airbox, and flows back in the oil.
Because of the low temperature of the oil, the condens in the oil will not evaporate complete and will become sludge.

The airbox of my Wee has a drainhose, with which I can drain condensation from the airbox. The problem is for most of the time solved now.

There has been many threads about having a "milky spy hole"

They all do that sir... when the weather is colder. Particularly if you are doing runs of less than an hour. The engine doesn't get hot enough, for long enough to clear the condensation from inside the crank case.

Unless the whole oil volume has turned milky brown don't worry.

You will also find the same emulsified oil in the oil filler cap during colder months. Again nothing to worry about.

OK thanks blokes that explains it really well for me I can stop worryin now

I cleaned the crankcase breather hose on the Punto yesterday.... about 1/2 in. bore and completely blocked with mayonnaise. Admittedly it doesn't get used every day, but not too many short journeys - perhaps it's a weather thing!

Just take it for a long ride .... I used to have this problem as my bike stays outside.... advice from this forum put my mind at ease ..... and it's an excuse to do long rides

and it's an excuse to do long rides,

Mine was the same yesterday, having changed the oil a few days ago. I cleared it today by getting the oil hot, then leaving it parked up with the filler cap off for a few hours in the garage.

Thought I had this cleared, but it's back already after 1st commute of the year.

Tried a piece of Duck tape across the radiator guard to get restrict the cooling, bike did warm up quicker but still the same end result 😥

Check the sponge in the air filter box too. It'll be gunked up with mayo.

[Mr Nick]

My L2 did that as well but none of my current bikes suffers from this issue: no sight glass, just good old dipsticks: stops the paranoia of seeing the oil every time! It's just a side-effect of the breather system being more restricted for the sake of overall emissions control.

Hi,

Thanks for the link to the article, which I have down loaded. I saw a lot of "mayo" in the crankcase breather in the air filter in December when I cleaned the air filter. I went on a very soggy trip to Scotland in September and my dealer said that this was the source. Since cleaning the breather - I made up a pull through with wire and cloth - I have not seemed to have any issues. However, I will  be going on a weeks trip to Spain & France in June and will recheck my breather before I depart.
