Holey DPF!

Lonestar,

Agreed. However, after $12k into this truck in one year for two dpf cleanings, three $600 tows, new doc, new filter, twice to peterbilt and cummins, 6 injectors and endless stress, all for a truck that does not yet earn me a living, I'll take it for now. I still have an 8-10 hour day at another job to keep me and family clothed and fed, after I run this truck 2-5 hours per day each morning.

I'm not biting back at you, but I'm at the end of my limits with this truck. Everything else about the truck is fine, it's only got 92k miles. It's mechanically sound, was taken care of maintenance-wise. Now I'm at the last stop before a delete and want to do everything I can before I have to go to the delete.

In practice, as the filter clogs, wouldn't it start asking for a regen? Holes or not, wouldn't the pressure differential start to register above 3hpa at some point?

I will be treating this filter as a regular 'maintenance' item, as that has been my life now for the last 18 months. However, if this allows me to be faithful in monitoring it and making a quarterly or biannual cleaning with compressed air, I'll settle with it.

I know the filter will not last forever in this state, but even with a purchase of $2k for a new filter every year or two, it's much easier to figure that as a cost to be expected than the time bomb of tows and cleanings, etc, etc, and no improvement.

I can hear Rawze yelling...fix it right!!

I can only figure that will happen when I get rid of this truck someday.

Thanks for hearing me out!
