Changing the small o-rings on the cam covers
I have a small oil leak on both cam cover. Should I remove the cam covers to change those o-rings ?

No other way to replace the o-ring. Item 28 is a snap ring.
Your probably due for a top end refresh, where you'd pull the intake, valve covers, and at the same time and replace vent hoses, knock sensors, flappy actuator, and repaint the manifold and valve covers.
Since that leakage is only weapage, you might want to try just degreasing the area and sealing it temporarily with RTV.

I wouldnt bother with it unless you were really considering repainting them. But I always reccomend that you replace the orings, most pay no attention to it but they are a pretty common spot for leaks. But I wouldnt do all that work just to stop the relatively minor leak. If you are however thinking you wanted to repaint them then thats the time to fix the o-ring leak

Luc,
If I recall correctly, there's a snap ring keeping that piece in place. You can easily remove it with snap ring pliers but you'll need to remove the cam cover. The elbows have a castle nut with a tab washer. For this one, you'll need to bend the tab back in order to unscrew the castle nut. I mention this because it would make sense to replace all the seals since you're in there. Plus if a seal (oring) has bone bad, it's likely that you'll experience other leaks later.

Hi...
I didn't even realize that this was a leak problem... So i didn't.... two months later I repeated my cam cover removal and replaced the o rings...
We used a buna N nitrile o ring that seems to be a little too big in diameter... but with a little oil it went in... no leaks!!
The original was totally flattened down as many orings on the engine are after 20 years.. It was more of a square cross section ring... in fact I thought it was a part of the sealing plug.. but as PET suggests it is actually separate...
Do it... and replace all other rubber stuff..
