Do I need to delete EGR?
Do I need to delete EGR?
The EGR works to minimize pollutants by recirculating a portion of the exhaust back through the engine. But because of all of the issues associated with the EGR, many operators opt to have it deleted.
Are there any problems with the ISX engine?
Like any other engine with an EGR, the system can cause some problems. On the ISX, it most likely has to do with a leak in the EGR valve. This is a difficult problem to diagnose, but monitoring the coolant consumption can help. If you notice that it’s using a larger amount of coolant than normal, it’s probably worth investigating further.
Are there any problems with the EGR engine?
EGR Engines still plague owners of older trucks with problems. While most of the early problems have been engineered out of the exhaust gas recirculation systems on today’s clean diesel engines, corroded coolers, stuck valves and other problems still plague owners of older equipment.
When did Cummins start having problems with EGR?
For example, engines engineered before 2002 will experience more problems with EGR compared to modern types. In 2008, Cummins began noticing the SCR system experienced failing revolving parts, interfering with the engine’s horsepower. Clogged inlets came about in 2010 when recirculation was occurring, also affecting HP.
Why are the Rockers on my Cummins ISX not working?
These bad rocker arms stick and smack the camshaft, causing the lobes to flatten. You can fix this failure by replacing both the affected camshaft and the rockers. If you don’t correctly diagnose the problem and leave the faulty rockers, then the same thing will happen to your new camshaft.
