Hi Guys,

Doing first oil change.Which is the correct drain bolt.The owner's manual shows 2 diagrams and says remove oil drain bolt 'B" .In one diagram 'B' is smaller bolt on the rear of the pan between the feeder tube and the larger bolt.In the other diagram 'B' is the bolt on the front of the pan between the two feeder tubes.In the shop manual it says the remove the larger bolt on the rear of the pan ,to the right of the smaller bolt. :!:

Thanks Michael

Yeah, it's the lower, smaller one. Something must have been lost in the translation . . .

The reason there are two plugs on the back of the sump plate is that the larger of the two on the right is simply a hangover from earlier models, (Sport i, Centauro, Daytona RS etc.) that had two oil return pipes from the spine which acts as a condensor for oil vapor expelled from the engine in service. V11's only use one so rather than modifying the casting they just put a plug in there. As Docc sez, the drain bolt is the central, lower one at the back. Use a new crush washer. For some reason broad sump drain plugs seem to like to come loose. I've never had one that's been on the point of falling out or heard of one doing it but I quite often find them less tight than I think ideal.

So, Pete, are you a 'sump puller' or can you be content to change the filter through the access hole?

I pull the sump. I hate the 'Manhole' it sucks, even with the correct filter tool its hard to get the filter tight enough and given all the tales of filters loosening I do 'em up good and tight with a strap wrench!
