My engine blew at 29,000; I personally asked the mechanic (a friend of mine) that was replacing my engine to see the DPF, the intake, etc; so I went in the shop and looked. These engines were not designed for the SCR system, so I had concerns that the emissions system is causing the issue. You would not believe how dirty the air intake, black carbon like material all over. The motor is literally being poisoned. I had my nephew who is a great diesel mechanic with me; he recommended that as soon the warranty is done, get the emission system delete. It may actually save the engine, if it doesn't blow before that. The trucking industry has had some of the same issues, my 2011 Peterbilt 386 had nothing but issues until I did the delete.
