I have cleaned the valve cover and the cover plate.
Leading evidence: 'Clean valve cover and the cover plate' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'tubes sparkes' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Clean valve cover and the cover plate' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

Suggestion
If the oil is at the arrow as indicated, most likely you need to replace spark plug tube and/or o-rings.

Using the same principle, AOS will be on the left side of the engine.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

hello,
first , good year celebrations for all.
since 6 months I have traveled 10.000km with my 996 C2 2000.
I enjoy driving it
but I just noticed a small oil leak
driver's side
zoom :
for the moment I do not have oil task on the ground...
have an idea about the origin of the leak ? engine rocker ??
is it serious?
is what I can safely lead for to the engine ?
when I did the engine oil drain there at 6 months, the valve cover was fat, but no oil drop.
thank you for your answers stef
Stef, can you take a better picture and or video to get a better look? I can't really see the angle.
That's funny Gonzo! I've never seen it that way! It's always been a sideways/confused mouth to me!!
Just a thought, but could the oil be leaking from a higher point and collecting at the point you are seeing? The oil you are seeing could be from the AOS or AOS bellows located in the same area but just a little higher.
If the oil is at the arrow as indicated, most likely you need to replace spark plug tube and/or o-rings.
The pic you posted is doing just that as well.
06stef, is this a right hand or left hand drive car? Your second post shows the right side of the engine (looking from the rear of the car). Using the same principle, AOS will be on the left side of the engine.
hello happy new year
ok I have removed the wheel left, I have removed the protective plate (before the wells spark plugs).
there with alot of fat at the cylinder 1 :
also a little on the cylinder number 3 :
and here's the cover plate, we see a fat trace which is at the cylinder 1 :
I have cleaned the valve cover and the cover plate.
I have driven 20 km and the vehicle is parked in the garage since two days.
the valve cover is clean :
no leakage during a long stop
So I have doubts for my tubes sparkes, what about you?
This is a source reference. Confirm exact model applicability in the original material.
