This is especially noticable if the bike has been sitting a while and if the weather's cool. It is water vapor condensation and it is perfectly normal. If you take the bike for a long ride and get it warm the milkiness will go away. Some people install shutoff valves to their oil coolers so the bike gets hotter in cool weather, or fashion oil covers to reduce airflow, but most people just go for a long ride instead.

Oil milk white


It might be as simple as a rainstorm blowing water into the crankcase via a breather tube or something. Drain it out and refill it with oil. run it for a few minutes, shut it off and repeat. It might take 3 or 4 changes to have it clear up. if nothing is wrong with your cooling system that is. Is the coolant level normal in the radiator?

Excess presure in milk crank case on street glide


What year????? Sounds like a breather problem. Does the bike get fully warmed up a lot of a lot of short rides???? It appears to have moisture/water in the oil. Should not have pressure in the crankcase.

What if I put to much oil in


If you put too much oil in, the crank shaft will pump it full of air and your oil pump (if you have one) can not pump the air filled oil. Result: no lubrication. If your engine uses the splash system, you will be splashing foam, not oil. result: poor lubrication. Recommendation: do not over fill. if it is over full now, drain some off.

Want to see what I am talking about? Put some milk into your blender and turn the blender on. After some period of time ... 30 seconds or more, drink the milk.

You didn't say anything about the make, year, model or mileage of your motorcycle, BTW.

2004 rmz 250 was riding started to smoke heavily from exhaust bike stalled no coolant in rss but nothing leaking ?


If it was white smoke coming out you may have blown a head gasket. If it is water cooled and there are no signs of external leakage then it only has one other way to go, inside.
If you have an oil dipstick, pull it out and check to see if your oil looks more like a milk shake sludge. Even if you can't see it, try dumping your oil from the sump and take out your oil filter. (unless it is a 2 stroke)

I ride in the rain alot on my 89 virago 250. I looked under the oil fill capo and noticed white residue like water has gotten in my oil. Drained oil and it wasnt white but the white residue has to be from...


Sometimes water vapor gets in through the vent in the crankcase and as the motor heats the only way to go is up!!!!! I wouldn't worry about it since you checked the oil and it looked fine. If it was a bad gasket or a craked head your bike would have a bad miss and the oil in the crankcase wouold look like milk...................

Pop noise with thick white smoke from front end,


sounds like you might have a cracked cylinder and oil puddled up inside over night and when you started it..it blew out through the exhaust. White smoke means oil...black smoke means gas ,and blue smoke means both..if you cracked a water jacket your oil will look like a bubbly milk shake.....take a look at your oil.

Normally water gets in through the head gasket, sometimes you can hear if the head gasket has blown. One way of finding out is to take it to your dealer and ask them to do a compression check that will tell you if you have a duff gasket. You will also notice a slight drop in performance.

Water in Oil!


I would go for the water pump seal first, it is an easy fix. Pull the left case cover and there it is. You will of course have to take the water pump cover off and all the plumbing that goes with it. Be sure that when you put the new water pump seal in not to put any lubricant like oil or grease on it. This is a ceramic seal and oil or grease on it will ruin it. There is also a spring in there that keeps pressure on the seal so replace that as well. You will see what is there when you get it apart. Replace any corroded/rusted parts. Take a good look at the impeller and make sure it is 100% while you are in there. Sometimes these will break loose from the shaft. If you have any questions about it replace it. If after that you still have water in the oil it would be a head or base gasket I am thinking requiring an adult to intervene, a qualified Ducati mechanic.
