Message:: [QUOTE="Humblepie, post: 8873534, member: 230041"]The first gen egr pushed way more soot back in to the motor. That caused problems with carbon packing which leads to premature cylinder wear. It also pushed more soot in the engine oil which led to premature bearing failure, oil filter plugging and rocker shaft wear. they had oil pressure issues which led to premature cam failure. They have and still have head issues the are only good for about 500,000 miles. The air actuated vgt isn’t nearly as efficient as the electronic controled Vgt. They are not a bad engine, but they are maintenance heavy engines. They were rushed into production and it shows. ‘15 on to current are a much better design.[/QUOTE]
