The engine began to fail because of a lack of adequate breathability into the crankcase, causing high crankcase pressure, excessive oil blowby, severe exhaust smoke, severe engine sludge, severe engine shuddering, and lack of response to the power steering because of engine power loss. The failure of the PCV system was at fault. Produced codes P0300, P0306, and P0430. Engine sludge needed to be cleaned, PCV hoses and PCV needed to be replaced, spark plugs needed to be replaced because of blowby, and valve covers also needed to be replaced because of sludge clogging the PCV baffles within the valve covers.
