Leaking oil

Hello guys, my engine has been leaking oil from the top cover for the last month but I didn't detect any trouble in the car or why is it missing oil and what should I do?

top cover has lost its gasket feature.

I agree with what honor says.

I hope there is no different situation thanks

I don't think my teacher is missing out because the gasket is worn out if there is no problem in the sound of the vehicle.

I have the same situation, I showed it to the master, 10 years of car sweats, he said. Let me have the cover checked then.

There was the same leak in my vehicle, the master said, we will do it when it comes to 10 thousand maintenance.

I'll take a look at it this weekend then
