Bottom end failure is likely caused by lack of oil or poor quality oil. Bearings are just interference fit shells, so they are heavily dependent on oil. Needle bearings or ball bearings are no more tolerant of insufficient lubrication.
What does low end gone mean?
This means that the car needs a new engine or a complete overhaul, the engine has suffered heavy wear and damage due to running without oil, or the owner neglected to change the oil, which led to a failure of the lubrication system. You need to replace or overhaul the engine

Probably the most common cause of engine damage is not enough engine oil. Even if you change the oil regularly, you should check the oil level regularly to make sure there aren’t any leaks or your car isn’t burning too much oil.
What can cause a main bearing to malfunction?
Extreme operating conditions such as overheating and ‘fretting’ cause accelerated surface fatigue and can overheat the bearing to the point of stripping. Oil starvation or inadequate lubrication is one of the most serious forms of bearing failure
What does a lower end mean?
Also called (in vertical engines): bottom end. the larger end of a connecting rod in an internal combustion engine. Compare the small end. the bearing surface between the larger end of a connecting rod and the crankshaft journal.
What causes the bottom end to fail?
Bottom end failure is likely caused by lack of oil or poor quality oil. Bearings are just interference fit shells, so they are heavily dependent on oil. Needle bearings or ball bearings are no more tolerant of insufficient lubrication.
What does it mean to overhaul the bottom end of an engine?
The lower end relates to the connecting rod and is essentially a complete rebuild. The connecting rod and all bearings are usually replaced at this point, and on average most people do 1 bottom end for every 2 top ends they do.
