Oil will leak when the exhaust is serious. Generally piston rings and cylinder liners. Some new engines or engines that have just changed the steel sleeve piston will have this problem for a short time, so it will be fine to run in for a while. If it is not right for a long time, check that the piston ring is misaligned and misplaced. If this is not the problem, check other places you have moved, such as the piston ring of the air compressor, which will also lead to serious oil leakage from the engine exhaust. But you said it was new. Is it a new air compressor?
