I’m not a diesel mechanic but not sure what you mean by ‘dusting’....Dusting generally means that unfiltered air (say, due to a loose or broken intake hose connection) enters into the intake manifold and scores the cylinders...Cylinder scoring can usually be found via a leak down test whereby the sound of air hissing into the crankcase is heard or crankcase pressure begins to rise (at oil fill cap)....Air heard hissing into the intake indicates a bad intake valve, while air heard hissing at the tail pipe indicates a bad exhaust valve.... Bubbles in the radiator indicate a bad head gasket...I would say that before replacing parts more diagnostics are needed...JMHO, I wish you well, sorry for your difficulties ...
