What type of gasket/seal is supposed to be on the oil sump drain plug ? the one on my 750 Paso just has a hard steel washer .. is this correct i would have thought that there was a soft copper washer or O ring seal that went on the plug, my bike has always dripped a little oil from what i thought was the joint between the crankcases. i was going to strip the motor to fix this oil leak but if it is just a ( hopefully) simple thing like the wrong seal on the drain plug then i will not have to do so.

Are you sure it is not aluminum? I believe that is what comes on it. I suppose anything would work (except steel); copper, nylon, or aluminum.

For my 907 (probably 750 is the same) I got the copper crush washers from DesmoTimes.com -- and I fit a new new one every time I drain the oil. US$1 each.

"This high-quality crush washer is superior to the OEM aluminum oil drain plug washer. It is malleable and offers a superior seal compared to the OEM plug washer. Suitable for all Ducatis EXCEPT testastretta motors on the 749/848/998/999/1098."

Thanks for the advice i thought steel was wrong. since i have had the bike it has leaked a small amount of engine oil from what looked like the crankcase half joint as you know the oil drain plug is sighted very close to this joint so i am presuming that the oil was leaking from the plug and running along the joint so it looked as though the joint was leaking. Iam going to just change the oil and oil filter and hopefully a new copper washer will sort it.

Cheers guys

It's supposed to be aluminum. They are readily availabale from any dealer for a few bucks. There is also one on the oil screen which is accessed on the swide of the motor.
