2000 996 coupe 6 speed - Leak from oil filter cover cap (screw cap)

[Philip54]

 

I recently changed the engine oil and I have now an oil leak from the oil filter cover cap that is quite noticeable with the engine running.

Everything looked normal during the re-installation of the oil filter cover cap after changing the oil and initially there was no leak.  I torqued the cover cap to 19 ft lbs  as I normally do and when I re-checked the torque after noticing the leak this morning, the cap moved just a little bit. 

What could be the reason of the leak?

I intend to install a new ring on the oil filter cover cap.  I assume that it is not necessary to drain the oil completely to do this.  How much oil should I plan to put in the engine?  Now the oil level is at 80% of the distance between the min. level dot and max. level dot on the dipstick.

Thanks

The filter housing hold less than one liter of oil; if you are careful, you will lose very little replacing the O-ring.  Also, make sure you didn't leave an O-ring behind when you first changed the oil (common mistake).   As for the oil level, you should be running it two bars down from full in the first place.
