Why is my Detroit Diesel 60 Engine producing black or gray smoke?
- MMitchell WestJul 26, 2025
If your Detroit Diesel Engine is emitting black or gray smoke, it could be due to several reasons. A damaged or dirty air cleaner might be the culprit, so replace or clean it. Another cause could be using the wrong grade of fuel, so ensure you're using the proper grade. Excessive exhaust back pressure can also lead to this issue, so reduce it. Finally, faulty injector timing may be to blame; in this case, adjust the injector timing.
