[QUOTE="SecondhandSnake, post: 11247804, member: 116684"] Bingo. Biggest issues on these engines are EGR coolers (to a lesser extent the EGR system) and the DPF. EGR coolers fail and you'll notice coolant loss and white smoke. They sell aftermarket ones that are more robust, or just flat out delete it. More robust ones will let you keep your emissions compliance, but deleting altogether will save you from any issues that arise from dumping soot back into your engine. EGR improves fuel economy/emissions and hurts reliability. Pick what you like best. DPF's are prone to plugging. That's just the nature of the beast. They're just a giant soot filter. If you do a lot of idling or short trips, you don't get it hot enough to burn off the soot in a passive regeneration. What happens when you don't get a passive one? You get an active one, which is just dumping extra fuel into the exhaust to burn off the soot. DPF's just aren't good for you. They're a massive restriction, and consume extra fuel during active regeneration. Although if you have a business and you're running these trucks hard, you may not see a problem. A lot of it has to do with duty cycle. You might also not have a choice to keep them legal. However I do know the Cummins ISB pretty well (granted not as much as the ISL-G) and it is a very stout motor. mifordman- Are you referring to Quickserve for the fault codes? [/QUOTE]
