Nissan Sentra 98. Published by manual-mecanica

I have a problem with my vehicle; it's consuming oil, but it's not leaking anywhere. I add a quart every four days. There are no stains on the engine, and it doesn't leave any residue on the ground in the morning. If you could give me any tips on how to find the cause,
I'd appreciate it. Thanks in advance.

Have you noticed if it's emitting blue smoke from the exhaust?

Take out the spark plugs and check their color. If they are black and have hard scale, then it's either the piston rings or the valve stem seals. Obviously, it will emit blue smoke, as Otho says. If it doesn't, then the problem is somewhere. Anyway, you're adding a lot of oil, so it must be somewhere.
