White Stuff in Oil Window

12-04-2004, 10:12 AM

Hello,

Can anyone help or give advice, I have the usual White stuff on the Oil Filler window, More than normal, In fact i cant read the oil even though i know its at the max level, The white stuff gathered in the Oil filler cap as well, its a bit guey!! but not really stickey this happened when i took her out for a run (30Mins), for the first time in a long time, It was to warm her up before an oil change, I have changed the oil and filter and im confidant its at the max level. (skill and judgement LOL, Made a make shift dip stick), My only explination is that the bike was running hot (previous owner had oil cooler set for winter changed that back now) and moisture in the engine has gathered on the window and in the filler cap as these would be cooler than the rest of the engine.... Anyway will this do any damage and is there an easy way to get rid of it or will it just desolve into the oil over time (now that ive changed the oil) Any advice or help. To give me pieace of mind please....PS the bike runs perfect otherwise and has full Ducati history, No smoke or any adverse noise 7K on clock, 3 Major services.........

Cheers

Hi JJ

"Don't worry Sir - they all do that"...!!

Nothing really to worry about, get some quality long distance rides out with your bike over the next few weeks and most of the 'mayonaise' will dissappear.

The problem with the oil window is that it's not 'flushed' with fresh oil unlike the rest of the engine, so the manky white stuff collects there, as well as the filler cap, and for those with IE engines - the oil temperature sender in the forward inlet cam cover.

Cheers.

.......and for those with IE engines - "the oil temperature sender in the forward inlet cam cover".

What's that - I thought the oil temperature sensor was at the bottom of the engine concentric with the little metal oil filter.

Maybe I have missed something.

There's two.

One in the 'sludge' filter (sump) and the other on the forward cam cover. So the injection system can look at both oil temperatures and make a decision from there.

I would offer to sell you a new head gasket set, but that's a bit cruel really, isn't it?

I had this problem with mine where I didn't ride it much over the winter. Someone advised me that when you get back from a ride take the oil filler cap off and leave it off while the bike is parked, so the condensation can escape.

Put the filler cap somewhere obvious so you remember to re-fit it before you go out again, or you'll have an oily boot! ;-)

I tried this at the weekend, and it seems to have worked. I've not ridden the bike since, but so far so good.

I did notice a bit of goo inside the oil filler cap too, so I wiped that out. Time for an oil change soon anyway methinks.
