Thank you for your prompt & informative response. My engine is 2007 in a Freightliner chassis and is in the rear. None of the gauges on the dash indicate any problem, i.e., temperature, oil, water, battery all register in the ok zone.
By damaging the turbo - what does that mean & how can I tell?
There is no item in the maintenance checklist called after cooler, but the "charge air cooler" was inspected and cleaned at 18000 miles in June of this year. The Inline Fuel Strainer, Cummins ISB02 Engine was replaced at 12000 miles in July of last year. I did read in another posting that many times the wrong mesh fuel filter may be installed but I'm not sure how I can even tell if that were the case. Assuming there are now contaminants in my fuel, even with a filter change, how do I get that "stuff" out?
And keep in mind you're dealing with an acknowledged "dummy".
