I'm going to pay the core on the next one, clean it and have one ready to go. Ridiculous what they get for a replacement.

Maybe you need to change the coalescence filter more often? The Cummins guy in my area that deals with school buses recommends 30-40K if I remember right...

I change the crankcase/coalescing filter out at 60k. You think it has something to do with the EGR sooting up? Cummins told me to have drivers High Idle to prevent this. I think it because those units that failed are on short routes and barely get over 45 mph. The EGR is not getting used enough IMO.

We change the coalescing filter yearly and have had no problems whatsoever with our DPF's. Alot of our newest buses are on very short intown routes (old directors gift to senior drivers) we do more lot regens on those but no other problems yet.

No EGR or Turbo actuator problems either? Actuator is about $900 BTW. I've had to force regen a couple of them but they are doing fine now. I will bring up the yearly filter change suggestion to my dealer and see what they say.

We had two turbo actuators but both were electrical in nature both under warranty (10yr 200,000 mi.all components).
