Can sump covers leak?

'00 C2 manual/Canada version, 94,000 km.

I've noticed some weeping of oil around where the edge of the sump cover where I'd suppose a gasket might be. Obviously, I'm well aware of all the usual, hysterical, awful possibilities. But the engine is dry everywhere else I can see, there is no smoke, no oil consumption, no puddle in the driveway, and the car runs like a champ.

Is it possible that the leak is just at the sump cover? Could find nothing directly relevant by searching.

TIA!

Bruce.

Sure, it is just a silicone bead seal.

I would clean it all off - drive the car and make sure where it is coming from.

Thanks, Loren. Will post back when I know something. Sometimes a cigar is just a cigar...

is the leak coming for the cam covers as well? I know the fix for that....

My visibility is limited to how far I can squeeze my melon under the car with a flashlight, unfortunately. Underground condo parking lot... no lift. But as far as I can see, it really is concentrated around the sump cover area. If it was coming from anywhere else, it would have to be something directly above that. The cam covers look dry, subject to the caveat above...

If by chance it is coming from the cam covers it could be the covers themselves or the spark plug tubes. Let me know what you were able to diagnose.

The tubes are relatively easy fix. Leaks from the covers can sometimes be remedied by just putting the special sealant on the bolts and re-inserting them without removing the covers themselves (a procedure which requires a special tool.)

That's very helpful, thank you. I actually replaced the spark plug tubes last year, so your hypothesis narrows things down quite a bit. I certainly like the sound of the simple repair! :)
