How To Clean A 6.7 Cummins Turbo
How to Clean a 6.7 Cummins Turbo
Before you start cleaning a 6.7 Cummins turbo, you need to know a few things about this engine. To begin with, you should make sure that your vehicle is operating at the proper temperature. You also need to wear protective gloves and long sleeves while working in this area. The mass airflow sensor is located on the turbo side of the engine and connects it to the exhaust manifold and the air intake. Once you have disconnected the air inlet, you can proceed with cleaning the turbo.
The first thing you need to know about cleaning the turbo is how it works. Its vanes are square and slide inside of a slotted ring. This slot changes in diameter with the direction of rotation. If you notice that the vanes don’t turn, it’s likely that the turbines are not spinning. Then, you need to clean the internals of the turbo. To do this, you must remove the turbo and use a special cleaner made for this purpose.
If you’re concerned that you may have a bad head gasket, you’ll need to clean it properly. Many of the 6.7 Cummins problems relate to the emission equipment. The sheer torque of a 6.7L engine can lead to head gasket failure. Another cause of a bad turbo is dilution of fuel. You can reduce this risk by doing an oil analysis.
Lastly, you need to clean the fuel injectors on your Cummins truck. If you’re not sure how to do this, visit IGOTACUMMINS for help.

Besides exhaust gas emissions, your 6.7 Cummins may experience power loss due to a clogged DPF. If the DPF is blocked, exhaust gases will flow into the turbo and cause back-pressure. This puts additional stress and heat on the engine, and it could even lead to a faulty engine. In addition, some 6.7 Cummins owners have success by pressure-washing the original 6.7 DPF. However, this may only be a temporary solution.
While you may be tempted to skip this step, you can always check your manual for the recommended cleaning interval for your 6.7 Cummins turbo. In most cases, the owner’s manual will tell you how often to clean the turbo actuator, but this is rarely followed and is not known by the average owner. This can dramatically decrease the mechanical performance of your turbo. If your vehicle has an EGR valve, this can contribute to soot buildup in the actuator housing.
Once you’ve cleaned the turbine housing, you can go back to cleaning the vanes and restoring your truck’s power. The next step is to check the exhaust brake. In order to do this, you’ll need to remove the turbo and ensure that the exhaust pipe is free from carbon, soot, and rust. Also, the exhaust brake will prevent soot, carbon, and rust buildup, keeping the sliding nozzle ring clean.
