Oil in coolant reservoir?

Doing some work on the bike and happened to pop the coolant lid off and noticed this. Looks like a bit of oil? Bikes Around 4K miles or so. Did last oil change in march and oil looked clean. No milky color at all. Coolant hasn't been changed. Any ideas?

Also it doesn't feel like oil or smell- but maybe it's cause it's so little? Has anyone seen rust right there? Seems to only be at the top? Possibly caused by the lid?
 
Here's what I pulled out. Very liquid. Isn't thick by any means.


Dropped oil- oil is clean- no sign of water intrusion at all. Where's the smart people at? Haha

Also curious about this. 1198 had a separate oil cooler and a radiator. 1199 looks like just a radiator on top and bottom... Whaaa?

Yeah i'm pretty stumped. Oil was fine. Flushed the crap out of the radiators and reservoir. In the reservoir there was blue stuff coming out too? What color is the stock coolant? Someone had to of put water in this one. I did not and the guy before me only had it for 800 miles. So that makes 0 sense. Unless Ducati uses a very clear water like anti freeze lol
 
I think the new bikes come with red coolant. That is most def contaminated. I think you can get oil in the water without cross contamination from probably a bunch of places. That really looks like oil. A guy in a town over had pretty much the same thing at least looks wise. It was a compromised o-ring gasket on the heat exchanger. Whatever it is, its not right.
 
Thanks for the first place to look. I will pull the exchanger and try to see if I notice anything.
 
Old bikes came with blue coolant the new coolant and replacement coolant is red.
 
Really? Nobody else has had this before? Think this is the first problem Ive had with a lack of massive feed back.
 
Probably not seeing coolant in the oil because it's on the oil pressure side.

Could always have it analyzed...

Blackstone Labs

Not sure if they'll analyze the coolant as well.
 
Your getting oil in the coolant. Not coolant in the oil. So you have a pressure oil side leaking in to the coolant side somewhere.

Coolant was red on your bike.


Lack of feedback is because very few have experienced this issue, I found anz in the corvette forums and told him the problem was not common before he posted his troubles here.
 
What color is the stock coolant?

My 13 is red fluid.

Its hard to find, but id not be putting anything back in yours until you figure this out.

For you to diagnose maybe add water and water wetter. So your not wasting antifreeze

Bingo. That's what I did. Waiting for my oil filter to come in- dropped the old stuff and thought I had a new filter. Put distilled and water wetter in last night. Flushed full cooling system with 5 gallons of distilled water. Talked to a duc mechanic last week and he said to empty and flush it well and refill and ride it for a bit-especially since its not going into the engine and see what it looks like at the end of the week. I have engine ice on the side once its fixed. Will test it and drop coolant again and see how she looks. If its still bad ill start by swapping O-Rings out in heat exchanger. Seems like its the easiest to access. Beyond that I don't know what else would cause it. :confused:
 
Someone else who has gone through these motors may wish to comment but these things are held together with 3 bond so virtually any place that gasket sealer separates these two fluids (pressure side) is suspect. I only mentioned the heat exchanger as I have seen a few of these gaskets fail probably due to assembly error.

Your not the only one to say it- a few Ducati mechanics have said their first guess is the actual exchanger itself being bad as well.
 
I'm also seeing some oil in my coolant (2012 1199s 4k miles). Doesn't appear to be a ton of oil but there is some. I will post up a picture of what I drained out of the system. Going to change the oil this week and see if coolant is in the oil as well.

Was your issue the heat exchanger as suggested?

Be a good thread revival if he answers. Not a record though. :)
