Engine Disassembling and Assembling
Note:
^ Replace oil cooler and thoroughly clean oil passages if you find metal shavings or small metal particles in the engine oil, caused, for example, by partial seizure of crankshaft and connecting rod bearings.
^ Faulty injector scan cause violent knocking noises in the engine which sound like faulty bearings. When this occurs, run the engine at idle and loosen injector line unions one after the other. If the knocking stops when a specific union is loosened, it is an indication that the respective injector is faulty.
