My s7 have very bad oil leaks, It almost leak like 1 litres per week if I drive it, but driving it seems fine no engine lights, I got the top engine seal repaired, but not helping, maybe it's the lower seal.

To do lower seal is it an engine out job, big money?

Is it worth it to repair or just drive as it is, it still drive fine, only take it to track or Long road trip, I drive my tesla most times. What could be the worst happen when oil leaks, do I need just keep refill every time I drive

Any advice please help
