Oil is overfilled been drained but still smoke?

If oil has been overfilled and is still smoking after being drained, it could indicate that oil has leaked into the combustion chamber or that residual oil remains in the exhaust system. This can happen if the engine was run with excess oil, leading to oil burning off or creating excessive pressure. It's advisable to have the engine inspected to ensure there are no underlying issues, such as damaged seals or gaskets, and to confirm that all excess oil has been properly removed. Continuing to run the engine in this condition could cause further damage.
