Hi all,

I am completely new to the Forum so hi to everyone.
I bought new Multistrada 1260S in April 2019 and have been enjoying it a lot.
Then, I suddenly discovered something what, it turned out, nobody can detect what it is.
I send my bike to 2 different Ducati service stations and both of them had no answer - they told me - ride more and see if this will continue and increase or it will disappear.
I will post pictures and explain a bit.
This are the pictures taken at the moment when I discovered this (after ca 3.200 km on the clock).
I don't know when it appeared, either just at that time or it was there for a longer time, or from the beginning.





First, we all suspected (were almost sure) that it was faulty valve cover gasket.
But after they wiped the oil trace and checked the bike, it turned out that valve cover was completely dry and they couldn't discover where it was coming from.
After that, I was riding more and I was forcing it to leak (higher revs, higher speed), but only what I dot whas this below.
When I wiped that again, I got myself a dentist mirror and checked completely closely the exhaust gasket(exhaust - manifold).
Now it looks like this:



It is definitely coming from there - from the bottom part of exhaust gasked on vertical cylinder- at the service, they are telling me that it is the leftover of some grease from the factory, melting, they cannot find anything else and they are persuading me that this is not a leak.
When I closely look the gasked, it seems a bit greasy and these are some burned spots on the exhaust around it - might be some grease - maybe they put grease in the factory when they assemble exhaust and manifold together?? - and they put too much this time
But still, can it be exhaust gasket leaking? I don't know how it looks when exhaust gasket is leaking - for me it would be strange to see oily, liquid texture - it shoud be just burned and dry if exhaust is leaking.
This what I am getting is oily and liquid - and it is not getting around the bolts and everywhere around gasked like on the first picutres, now it is just a tiny oily trace at the middle of the exhaust gasket- and not even close to qty like it was when I first discovered it,
Do you have any idea what this could be?

Thanx in advance,

Greetings from Croatia,

To me, it looks like it's leaking above the exhaust and then running down and around it.
Hi,

Thanx for the reply.
Well, this was what we all thought at the beginning, but it turned out that it definitely is not that.
Above exhaust is completely dry, and when everything is wiped and dry, it starts to appear exactly as tiny trace just below exhaust.
Situation how it looks after it was wiped is on the picture 4...

And from your point of view, can this be an exhaust gasket leaking? (this is liquid, oily trace)
Or when exhaust gasket is leaking, it is not oily, just black and burned?

What does the smell test say? Shit, I'd taste it. It looks like motor oil. You indicate that the flow has lessened as you've wiped it away. Hope it gets smaller and smaller.

FWIW I have an oil weep or something around the filter screen and it's annoying but leaves no oil on the ground or inside skid plate, doesn't affect the level, and isn't coming from the screen plate. Oh well!

Smell, I don't know as I didn't smell it, but to the touch, it seems a bit "thicker" than oil.
And it seems to be getting smaller and smaller after I wiped it...
If this doesn't look like exhaust gasket leak, then I would really think that it is a leftover of some grease from the assembly - just as they say at Ducati service.
I need to wait till spring now, to make some more km on it... then we will see for sure if it is increasing or disappearing...

I'm going with assembly lube. My guess is some guy on the assembly line came back from his lunch of soppresatta and chestnuts and washed it down with an extra glass of vino. Just a guess.

Let's hope this is the case... If so, I would pay this guy another lunch:D
Some guys were telling me it could be head gasket actually, and that this could be the oil that is circulating through oilways inside head and finding it's way out...I don't like this scenario
:mad:
