Ducati Valve Cover O rings

[He Man]

How often should the valve cover O rings be replaced?
DS1000 463.2.010.9A

I'm gathering all my stuff for the 18,000 mile service and am looking to replace these rings.

The obvious answer i think is every time you removed them, but im making sure.

Its $4.99 per an O ring ( talk about overpriced!) Is there an outside source for these? Think McMasters will have a pack of them?

Another Question: CA-Cycleworks Fiber gaskets for alt and clutch side cover? Whats the alternative? Can that Permatex Gasket Goo work?

OEM fuel pump flange o-ring $28 now that's overpriced

NAPA is a good place to find these things for cheep, just have to know the size

McMasters has a bunch of sizes in stock, but Is there anything special about the ducati ones that I should know about?

They have ones from 200-300 and 300-400 degree range. The heads are hotter than the oil, so i assume i should go for the 400 max temp one...

The valve cover O-rings seem to survive pretty well.
Doubt you'll need to replace 'em unless you damage 'em somehow.

ThreeBond 1194 for the sidecovers.
Also known as Yamabond, Hondabond, etc. depending where it's sold.

thanks speeddog.

Ill check the Orings, one of my valve covers keeps leaking oil. The others are fine. Maybe ill just replace that 1 ring and see if it solves the problem. It doenst look deformed or anything.

1 3.5oz tube = enough for 2 side cases?

I had our gaskets made because I never get the goo sealant amount correct. I think I did one 900ss's alternator cover 3 times before it wouldn't leak oil.    I blame my start with turning wrenches on 1980+ Japanese bikes. Their gasket surfaces are better than Ducati.

Plus, they're reusable, so if you want to make a change to the pickups on a carb'd bike, there's no need to clean off and reapply goo. Or on the wet clutch'd bikes, it lets you go in time and time again trying to get a certain aftermarket clutch pack's stack height juuuust right.

Nearly a lifetime supply for your own bikes.

I spread it pretty thin with a plumbers flux brush, haven't had a leak yet.

The goo is really nasty.

I used Chris' gaskets.  Just be aware that on the alternator side, the gasket thickness requires a thinner brass spacer for the timing pickup.  I sanded mine and measured the gap with timing feeler gauges.  Easy, once I figured out what was going on.
