Symptoms that indicate the Dodge, Ram 6.7 diesel particulate filter is clogged include: Others decide to delete the DPF completely. Some have success in washing out clogged diesel particulate filters. As such, it’s important to ensure your 6.7 Cummins DPF is functioning properly. This causes a build-up of back-pressure for the 6.7 Cummins, which can lead to more heat and stress on the engine. It’s pretty bad for a turbodiesel engine to run with a highly clogged exhaust DPF. However, it still affects many trucks – especially as mileage builds up. This helps reduce particulates, so DPF clogging is less common on the later year 6.7 Cummins. In 2013, Ram pickup trucks receive SCR emissions control systems along with diesel exhaust fluid. These clogging issues were so problematic early on that Dodge rolled out multiple PCM re-flashes in an attempt to reduce the occurrence. This in turn leads to more particulates (soot), which can quickly clog the DPF. Without DEF the B6.7 diesel must run a little bit on the richer side to reduce NOx emissions. Initially, Chrysler opted to avoid using diesel exhaust fluid (DEF). Throughout the rest of this post we’ll discuss each of the 5 problems in-depth and finish off with overall thoughts on Cummins 6.7L reliability.ĭiesel particulate filter (DPF) clogging is a common problem on the Dodge, Ram 6.7 Cummins. Nonetheless, many of the B6.7 Cummins engines suffer from the above faults. It’s natural for all engines to have a few kinks in their early years. Certain years may be more prone to these failures – specifically the earlier model year Dodge and Ram trucks.
Rather, when problems do happen these are a few of the most common.ĭodge and Ram trucks have also been using the 6.7 Cummins since 2007. That doesn’t necessarily mean they affect a huge number of 6.7L Cummins diesel engines. We’re referring to these issues as the most common. It’s a good time to add a few notes that apply to this article. However, the turbos and head gaskets are known to run into occasional failures too. Problems with the Cummins 6.7 often come down to emissions parts. 5 Common 6.7 Cummins ProblemsĪ few of the most common faults on the ISB 6.7 liter Cummins turbodiesel engine include:
In this article, we discuss the most common problems on the Dodge Ram 6.7 Cummins engine as well as overall reliability. However, no engine is perfect and the 6.7 Cummins diesel is no exception. Many also associate the Cummins name with some of the best light truck diesel engines ever. As of 2021, the 6.7 Cummins offers an impressive 400hp and 1000tq. Though, it’s been through a few updates over the years. The B6.7 Cummins still lives on in Ram 25+ trucks to this day. It’s a straight-six, 24 valve turbodiesel released for Dodge Ram trucks in 2007.
