Temporary oil leak

Hello guys, I joined the forum today. I wish you all a good day. My problem is this: 307 1.6 My gasoline car has been with me for about 14 years. A week ago, I noticed oil leaking from the middle of the engine. However, there is no leakage at the moment, but no oil shortage. I had an oil change recently (1 month ago). It attracted a lot of attention. Because it has never happened so far. The area where the engine top gasket is located is clean. Can it be caused by the lid of the filter not being properly tightened? Thank you from now.

This may happen because they do not properly install the oil filter cap after an oil change. like you said

Thank you. Let me check it out. If there is another situation, I will share. I wish you a good day.

I had it checked. No problem in the Oil Filter cover. I think he's missing from the oil seal. The masterful way seems.

I show it to the master, "sweating." There is no drop in oil level. I think it's normal.
