RE: smoke
The old turbocharger locked up due to:
- Oil starvation due to low oil or neglected oil change.
- Lack of cool-down idle after a prolonged freeway run in a hot climate.
- Lack of coolant supply (unusual, unless the coolant level is low).
Oil leak at the bottom of the oil return line is a known problem and it should not cause smoke from the tail pipe. Have the seal ring replaced. If the leak is from the oil supply to the turbocharger, have the problem corrected. Pics would be a great help.
I recommend using synthetic oil for turbocharged engines.
