EGR Issues-Interesting Read

The following info I found on Wikipedia on Cummins B Series Engines. I'm posting this info up mainly for the benifit of the newbies.

6.7 emissions control issues
The exhaust gas recirculation (EGR), and diesel particulate filter (DPF) implementations on these engines offered in 2007.5+ Dodge Ram 2500-3500 trucks are plagued with problems, ranging from soot-plugged turbos (which creates another subset of problems in itself), soot caked intakes, and plugged DPF filter systems.[citation needed] These systems, mandated by the United States Environmental Protection Agency (US EPA) as per the 2010 diesel engine regulations, also cause a drop of at least 25% in economy. Similar legally mandated systems on competing diesel engines such as the Power Stroke and Duramax have been mostly trouble-free, and without such large-scale negative impacts, providing hope that these problems may be solvable on the B series with future design revisions, and possible manufacturer recalls. Chrysler offered many owners to buy back their vehicles.[citation needed] Chrysler suggested that owners "drive it hard, drive it fast",[cite this quote] but it is not always possible or safe to do this, and it may result in failures of the engine and other powertrain components.

Under warranty, all problems with the engine and powertrain will be repaired, as long as the owner has not removed any of the emissions system, or installed any other potentially warranty-voiding devices. Warranty repairs can prove to be problematic for owners, as warranty repair policies may vary from dealer to dealer.[citation needed] However, under US law, all problems related to emissions systems must be covered under warranty for five years or 100,000 miles (160,000 km) (significantly longer than the standard warranty); dealers refusing emissions-related warranty repairs risk legal punishment for both themselves and Chrysler Corporation.

Many owners have decided to risk voiding their warranties by removing or disabling the EGR and DPF items on their trucks, resulting in a much more reliable engine and truck with better economy.[citation needed] Similar action has been taken in Ford and GM Diesel equipped trucks, with similar results. Although removing the EGR and DPF results in increased Nitric oxide, Hydrocarbon and particulate matter emissions, Carbon monoxide and Carbon dioxide are drastically reduced.[citation needed] Hydrocarbon and particulate matter are only slightly increased since the deletion of the EGR actually reduces these emissions. EGR deletion (deletion of the EGR only) is considered justified by a wide range of people, including environmentally conscious persons.[citation needed]

2009, 2500 Ram Quadcab, Longbed, G56.

I like the fact that it is informative and is factual. I appreciate the fact that it mentions the problems associated with the emissions systems and also that removing the emissions cures the problems as well as improved fuel economy. Thanks for posting!

Something to consider about emissions:

2010 CA smog check.
