Minimum oil level

Good evening everyone.

I have a problem with my car (a 2003 Hyundai Accent).

About a month ago, I noticed the oil level was very low. I check it in the morning, and the dipstick shows the minimum level. I changed the oil, and a week later, when I checked again, it was even lower than the minimum.

What could be causing this problem?

It's worth mentioning that it's not leaking oil from the oil pan or any other part of the engine, as I've checked thoroughly, and it's not emitting much smoke from the exhaust either.

I would appreciate any help because I really don't want to open the engine, and I suspect that's the problem...

Thank you, and Happy New Year!

Change only valve seals will love you quite a lot depends on km. That you have for the rings or a good warm before the seals of these cars come out as a stick. I hope it serves what has already been seen. Good luck friend
