Default Re: Diesel Particulate Filter Problems

Elks, our first Western Star with DPF on 1000hr/50k ish km just yesterday was de rating due to faulty '7th' injector and would not burn off. The first of many I'm sure. The Isuzu electronic injectors inject on each exhaust stroke when burning off, which proved reliable, but after full regeneration (20 mins) you could see the oil level had risen on the dipstick from some diesel working it's way past the rings, not a major if serviced at the recommended 15000km but will cause big problems for companies who stretch service intervals. I'm sure it will be worse with lazy car owners.
