Hello everyone,
I have a little oil seepage that I need to take care of. Apparently I have two valve covers seeping oil, the ones closest to the exhaust port are the culprits. However, I want to take care of it now and change all of them. The previous owner said that he had the valves adjusted and that the gaskets were probably not changed when done.
Now can someone please confirm if possible the size of the o-rings?
I have done a little research and found that there are two sizes, they don't differ much but they both have the same part number of 88641381A but one site has a size of 63.13 X 2.62 and another of 63.17 X 2.62. Now I know that the size discrepancy isn't much but we are talking about oil leaking here and rather be safe than sorry. Who knows, that discrepancy may very well be the reason for my leak.
I wouldn't fret about a difference in the description of the size, I consider that a rough guide at best.
You're going to get whatever size they're using, as there's only one part number.
You can go with these:

Or get OEM.

Thank you for that, do you think adding some Silicone Gasket for good measure is redundant?
The o-ring will seal fine all by itself.
Make sure both the groove in the cap and the spigot in the head are clean.
Confirm that the bore and chamfer of the spigot are smooth, no burrs or scratches that will damage the o-ring.
A very light coating of grease on the bore and chamfer, then steady hand pressure and a bit of wiggling and the cap will go in.
Don't use the screws or a hammer to install the cap.

Thank you for the tip, I have a felling that after the valves were adjusted the covers were improperly reinstalled.
I will keep in mind the link you gave me, I do however, have some ProItalia points that need spending :D apparently they have OEM which I am sure is close to the quality in the specs listed in the one you directed me towards. After all...it's DUCATI OEM so it's gotta be good right?
