Why is there excessive black smoke coming from my Doosan Engine?
- D
  David MoodyAug 9, 2025
  Excessive black smoke from your Doosan Engine may be due to several reasons. The air cleaner element might be clogged, so try replacing or cleaning it. There could be restrictions in the air duct, which you should check and correct. Another potential cause is leakage at the intake manifold, so inspect and fix that as well. The turbocharger could be seized up and not rotating, or the turbine and compressor blades might be damaged or in contact with each other, requiring disassembly, repair, or replacement. Finally, the exhaust piping could be deformed or clogged; check and correct it.

  If your Doosan Engine is making unusual sounds or vibrating, the rotor assembly might be coming into contact, or the rotor rotation may be unbalanced, either of which would require disassembly, repair, or replacement. Also, the engine could be seized up, which would also require disassembly, repair, or replacement. Check if each joint loosened and correct.

  Excessive white smoke from a Doosan Engine can be caused by an oil leak into the turbine and compressor, which requires disassembly, repair, or replacement. It may also be due to a worn or damaged seal ring because of excessive bearing wear, also requiring disassembly, repair, or replacement.
