Subject: Sump spacer gasket swap Tue May 05, 2020 9:48 am
After reading about the various sounds of motors disintegrating I decided to invest $5 (plus shipping) in a new gasket. The process went according to plan, following the instructions in the service manual, with two caveats:
There are 14 screws around the perimeter of the pan, plus four in recesses around the oil filter that are not mentioned, total of 18 not 14.
The two 4 mm screws securing the oil pickup had blue threadlock from the factory. I followed suit.
Wings, headers and kickstand (I let it dangle) were removed, two bolts securing oil cooler to spacer were removed. I left the oil filter in place and saved the oil as it had recently been changed.
Gasket was in good shape, the lower gasket came off in pieces and was also replaced. No debris inside the pan and nothing on the magnet. My bike has low miles and is not ridden hard. I feel better knowing it's done.
Thanks for posting this. It’s the exact issue that is the reason I’m picking up a new to me 2013 GRiSO tomorrow evening. My Stelvio had a couple of momentary low oil pressure fits so on advice from Pete Roper I’m fixing it with a new sump spacer gasket. Problem is, no stock for the parts here in Edmonton. Taking forever to get from Italy to Canuckistan. it was the opportunity I needed to explain to my wife the merits of a second Guzzi. I’ll be riding by Thursday :
I just did the same thing this past weekend. Both gaskets were intact, so, cheap insurance I say. Who wants to worry about loss of oil pressure in the middle of BFE on the next road trip.
MG Cycle provided the gaskets. The cost was less than ten bucks and I received them in a few days.
Was a good opportunity to pull the canister too.
Yes I did order the upgraded sump spacer gasket from MG. My dealer could not figure out the correct part # . Now I'm kicking myself for not ordering it all from MGC, but then again the $35.00USD worth of items I ordered from Wisconsin will end up costing me approx. $125CAD by the time it gets here (Thick spacer gasket , oil filter wrench, and some crush washers). I'm hoping the dealer is open to some guzzi education and will be willing to stock at least some of the basics. They are new to guzzi ,having taken over the brand from the previous shop that went under, after building themselves a monster huge multi brand superstore.
Want some from the US, I have a big stack in stock?
Same old gasket forever. Should be lots around.
Thanks GS I think I'm sorted for now. Not sure who is who in here other than Pete but if you want to PM me and introduce yourself I would be happy to have you as one of my resources. by Thursday morning I'll be riding a GRiSO so the panic for the Stelvio parts will be gone. Driving a cage to work sucks!
I’ll be doing this soon too. I understand this upgraded green gasket is needed for the spacer. How about the lower sump gasket? Is the OEM one ok, or also a failure risk? It looks like AF1 stocks the upgraded spacer gasket, but only the OEM version of the lower gasket.
The lower gasket doesn't have any pressurised galleries running through it so it's fine. Having said that the aftermarket ones I get are all made of the same thicker material as the spacer gaskets.
Some people have enquired as to whether any other substance, sealant or whatever, needs to be used on the new gaskets? My answer is no. We simply wipe the mating surfaces dry and install the gaskets dry.
One other thing that Michael mentioned is that it is important when re-installing the oil pick ups to ensure that they pass through the sealing o-rings in the cases cleanly. The end of the pipes can benefit from a thin smear of grease or oil and should we wiggled until you can feel them slide through the o-rings. The reason is that the brackets that attach them are really quite flimsy and it is possible for the bracket to bend before the pipe passes through the sealing o-ring and the pumps can then be compromised by 'Sucking air' leading to oil pressure warnings etc.
Now for people who have recently done the gasket swap please don't go tearing your hair out and thinking you need to do it all again because you don't. If you have been running the engine with no pressure warnings or 'Oil can' icon on the dash you're fine. Michael just felt it was important to mention it as he had the issue on Mark's bike when he built the 1400. Look at how the pick-up retainer plates/brackets sit before you remove them and then make sure they look the same and are un-deformed before you whack the sump back on. That's all.
Thanks Pete! And thanks to Michael for the additional instructions. I’ll try not to hamfist it.

Subject: Upper sump gasket thickness? Thu May 14, 2020 11:08 am
Lads, can some of you give me a measurement on the thickness of the upper gasket? I ordered two gaskets to do the replacement on the GRiSO and the Stelvio. When I ordered them it showed the green gasket in the photo of what I was ordering But what was delivered was two grey in colour gaskets, they look to be good enough quality and are .5mm in thickness.
Are the green gaskets .5mm or are they thicker? as I don’t want to replace them with the same as what’s there already and working fine so far. If the ones you guys are using are .5mm then I will go ahead and use the grey ones and if not I’ll source the green ones.
I arksd the young apprentcreature at Dan's if he knew how to read a VC the other day, he said "Of course?" While looking at me as if I had just asked asked him to stick his head in a bucket of turds. So I flung a 0.85mm head gasket off an 8V at him and gave him my calipers and asked him how thick it was. "A bit under a millimeter." He sez.......
And people wonder why I drink!

Thanks for the update Pete, I will have a look for and fit the meatier green ones. I am not sure if any European supplier has them, if not I will order from the USA. (I use the same Verniers also)
Good to get the thickness clarified
