Water is thinner than oil...

 

Actually oil is less dense then water, but heavier than water. So are you saying water can leak thru a gap smaller then oil can leak out of? I know the oil companies say one of the main reason oil has a shelf life is moisture can get into a sealed plastic bottle. jmn1960, have you still got the milk oil? Put it in a sealed jar and let it sit and see if water shows up on the bottom. Your're using a GL5 oil that has a lot of additives. Know this is not an oil thread but the call out is GL4 since your shift forks have bronze on them.

 

Try changing to a different brand of gear oil, and see what happens...

 

no already dumped it ,, is gl5 bad for the trans? I went with valoline 75/140 synth this time, thought gear lube was gear lube,, do I need to get it out of there?
thanks

 

Read your manual it will tell you what types of oils to use in each hole

 

well went to the trash and pulled the Valvoline bottle out and it is GL4 rated so mabe ,, we will see,, gonna be pullin that dipstick on this change more often than usual to keep an eye on the color of that oil ,,,
thanks guys & gals

 

Here is a link. Best of my knowledge from reading what the makers say, I just try to quote what they say and not what someone says that it work for. Interesting that you say your Valvoline is GL4. I have a container that says GL5 and we used it in a limited slip rear end in a Mustang.

GL4-GL5 no biggie, the GL5 has a slightly better additive package. Might help, won't hurt. Do you wash your bike when it's still hot? If you do, the tranny can create a vacuum when it is suddenly cooled by the wash water and actually suck water into it. Stranger things have happened, so don't be alarmed. I never wash a hot bike.

 

it said that it was both GL4 & GL5 compatable and yes limited slip also

and no I never wash the bike hot

oh well I guess it will me a mystery why the oil came out like milk,,it has got me puzzled but not gonna loose any sleep over it ,, just though it might have been the brand of oil and someone got the same reaction , but I guess not h\oh well

 

I have had it happen only once and agree that it is from moisture. How it got in there I don’t know — through the vent hose, condensation and a lot of short trips where the bike doesn’t get hot enough to evaporate the moisture I guess.
