Can a blocked DPF affect the turbo?
A blocked DPF prevents exhaust gas passing through the exhaust system at the required rate. Increased exhaust gas temperature and back pressure can affect the turbocharger in a number of ways, including problems with efficiencies, oil leaks, carbonisation of oil within the turbo and exhaust gas leaks from the turbo.
How does the DPF work on a Duramax truck?
Take your Duramax-equipped truck out for an extended straight drive, such as on the highway. The DPF will fill up with soot during typical operation, such as stop-and-go driving. The DPF system will store soot during this type of operation, but the engine will not get hot enough to engage regeneration mode.
How do you remove a DPF from a truck?
Remove the 3 isolators using the specialized pliers (Lisle 38350) or any other method you like. Push the unit to the BACK to clear the studs and angle the front of the DPF DOWN – and then push it forward so that the metal piping will clear the cross member. Once the piping is clear, lower the jack and remove the DPF from under the truck.
When do you clean a Duramax diesel engine?
On the Duramax diesel engines, cleaning of the DPF happens automatically. Take your Duramax-equipped truck out for an extended straight drive, such as on the highway. The DPF will fill up with soot during typical operation, such as stop-and-go driving.
Can a blocked DPF cause a turbocharger failure?
A blocked DPF prevents exhaust gas passing through the exhaust system at the required rate. As a result back pressure and exhaust gas temperatures increase within the turbine housing.
What are the problems with the Duramax DPF system?
The DPF system is extremely complicated but all problems boil down to excessive regeneration or regeneration interruption. These problems can be prevented by ensuring you are driving your Duramax on the highway enough and being cautious of not interrupting the regeneration process while its taking place.
Why is my Duramax diesel engine not working?
The trucks computer keeps track of how much fuel needs to be added or subtracted from each individual cylinder to make the engine run smoothly, and this value is called the balance rate. If one cylinder is contributing too much or not as much as the rest, the cause is usually a bad injector and the cure is a replacement.
What are the most common LMM Duramax engine problems?
1 DPF system & active regeneration 2 Leaking transmission lines 3 Fueling / low fuel pressure 4 Piston / crankshaft failure 5 Allison 1000 power limitation
What to do if your Duramax engine is leaking?
These problems can be prevented by ensuring you are driving your Duramax on the highway enough and being cautious of not interrupting the regeneration process while its taking place. Using a fuel additive such as AMSOIL Diesel Concentrate can help the fuel burn cleaner and therefore reduce particulate build-up. 2. Leaking Transmission Lines
