Oil leak need your advice please

I noticed an oil puddle about the size of two quarters ($.25) right under the two overflow hoses hanging out the bottom fairing. I took the side (and half the bottom fairing) off and it looks like oil was leaking from the oil hoses where they connect to the engine right above the oil filter.

I have a 2009 1198. It has just done 16k miles. I had the full service done at 15k miles. It has never leaked oil before.

Question, are these oil lines disconnected when performing the 15k service and is it possible the mechanic never tightened them properly, or could there be something more seriously wrong? The bike has been, and still is, running fine. Also I could tighten the lines a small amount, say about 5% of a turn.

Anybody ever have a similar issue?

Thanks in advance.

There is no reason for those lines to of been disconnected.. i venture to say its a legitimate leak and have someone check it out for warranty work... or it vibrated loose.
Those are the lines for the oil cooler below the radiator.
you still under warranty?

^I am, but now live in Guam and there is no Ducati dealer here, so it's going to be hard. I want to try fixing it myself if possible.

Yes those are the two lines connecting to the oil cooler under the radiator. How tight are they supposed to be? Pretty tight i guess since they have to deal with oil pressure but do they have a torque setting? (edit - no torque setting on the hose part of the connection as it uses o-rings, but the fitting that screws into the engine does have a gasket and torque setting. I'll have to run the engine with the fairings off to see exactly where the leak is comming from i guess).

Are the o-rings failing and is there anything else that could cause a sudden spike in oil pressure, perhaps?

Often when the rocker cover is removed during a service a small quantity of oil spills onto the cooler and eventually drains down into the lower fairing. A good service guy will wash it off but some don't bother. My guess is this is what you have encountered. Give it a degrease and see if the oil comes back after a short ride. If it does you have a leak, if not no more worries.

The oil lines are a tapered seat without O rings and should not need to be very tight to seal properly.

appreciate the feedback eltwin. i have put more than a 1,000 miles on the bike since the service so i doubt it was because of spillage, but you never know. i tightened the oil lines a tad and went for a short ride, and so far so good, no oil. to make sure i'll check it again this weekend when i have a chance to do a longer ride.

funny thing... i was waiting at an intersection for the light to change and decided to rev it up a bit to get some oil pressure going. afterwords i wanted to inspected the area where the oil was leaking from and saw a big puddle on the pavement. i though oh sh!t this is bad and drove on very slowly. turns out it was water from the air conditioner in the a car that was waiting at the same intersection before me.

Having had the same experience and momentary panic I can laugh about that one with you Doors.

Jim Morrison wouldn't have worried so much Doors!

Hope a nip up on the oil cooler hose connectors seals it. This can twist the run of the hoses a bit though.

Check your oil filter. I had a similar issue and the filter had loosened just enough to leave small drops of oil.

Did you find the source of your oil leak? When I got home last night, I noticed have the same leak. Looks like it's running down one of the tubes underneath.

i did. i tightened up the nuts at the ends of the two oil hoses (between 5 and 7 on the diagram) a tad and that seem to have done the trick. I checked all the connections for good measure.

Had oil leak on the same spot. Tighten up the screw did the trick. Thanks for the picture.
