Just purchased a 07, 5.9L. I am totally new to the diesel product, however after driving it home I am so impressed with performance as well as fuel economy and up here in Canada fuel is a tad pricey.
Question though spordically it makes an odd knock with what seems to be coming from below passenger area or by drivers feet, this happen at idle or when pulling away. No change in engine rpm, or other indication of load, but I guess its a diesel and will not notice that change.No signs of leaking fluids, all fluid levels are up. Is this a trait of these vehicles, as I said I am completely new to this line.
