New Crush washer oil leak ?

Oil drain plug for sump,, put in new oil , and put back clean sump plug with new crush washer and its leaking ????????

Maybe broken? I had one leak once, when I took it out it had snapped so was leaking through the gap.

Only problem is you'll have to catch the oil again so a bit of a PITA.

Worst one was with my car (Audi S4),the drain hole in the sump has a couple of ridges in it so the copper or ally washer needs to deform into them - no idea why they make them like this as it just seems wrong?

That said I'd never had a problem before until this year when I couldn't get it to seal. I tried 4 different (motor factor) washers, all leaked, I then drove over to the local Audi dealer to get some genuine washers just in case the generic ones were no good, I tried 3 of them and, each time it would drip, they were exactly the same.

In the end I found a spare sump plug for my Son's Ford Fiesta which had the same thread but a thick 'O' ring rather than crush washer setup and that worked perfectly, cheaper too, in fact a new Fiesta plug with 'O' ring is cheaper than the crush washer alone from Audi.

So I ended up doing the oil change 7 times, funny thing was after each change I seemed to 'lose' a bit and had to add a little more to get the correct level....

had another look its not the sump plug.... The leak is off the crankcase 22mm bolt mesh filter which also has a new crush washer ,,,, i will have to replace it with a new washer or Dowty seal .

Much better, no need to drain the oil to replace it.

then why is so much leaking out???

... maybe i will have to put the bike up on some wood so the side stand tips it over more to the left , and remover the filter then ,,

I wouldn't take that filter out without dropping the oil first.

Rather than wait for a post bleating about your bike falling off blocks of wood when you put a ratchet on the filter cap..

The oil level is way above the filter housing, just look at where your oil level sight glass is.
Simple way is just to drop the oil if you can be sure of keeping everything clean enough to re-use the oil.
Cheater way is to lean the bike against a solid bench, which itself is against a solid wall, but have a mattress or layers of cushions against the bench, better still take the tank and seat off as well.
This can be a two or three person job to lay it over gently and depending if you are A Schwarzenegger, also to get it back upright.

Also be mindful of the battery vent tube if you still insist on using one of those old fashioned vented lead acid batteries.

I did this a few times when assembling the Commando as there is quite a bit going on underneath those. I even had it on it's side on the floor, which would also be perfectly doable with a Monster.

I’ve laid race bikes down on a couple of old tyres in paddocks, more for the time saving than anything else, when you have to be back on the grid in half an hour.

Back when everybody drove around in Minis. A mate of mine who was expert at every aspect of mending and customising Minis, would just roll them onto tyres to work underneath.. Simples.

Dukedesmo · 14-09-2024, 11:17 AM

Granted, it's lower than the top of the oil but by 'extreme' leaning it could be done - there are those that will take the left side cover off to get at the flywheel/alternator/starter etc. without dropping the oil.

Probably easier to drain the oil though...

jerry · 14-09-2024, 04:33 PM

i will drain the oil anyway dont need more trauma

jerry · 19-09-2024, 01:28 PM

OK now sorted but new problem received clutch master rebuild kit from Ducati paddy and it was missing the wiper seal even though it was a sealed Brembo pack ?? Paddy is sending me another one ,,he is a good bloke ...

i will try and source a seal as its useless without one

jerry · 19-09-2024, 03:39 PM

NOOOOOO!!!!!! still leaking new crush washer from Luigimoto torqued up ,,, might be the little flat bladed screw thingy underneath the mesh filter ?????????

rollo22 · 19-09-2024, 06:48 PM

On the EVO engine the strainer washer only goes in one way
Just a thought
