INITIAL INSPECTION AND GENERAL CARE 

  1. Carefully inspect the air cleaner, air cleaner duct, and the exhaust manifold for any foreign material. Objects left in these areas can severely damage the turbocharger immediately on engine startup. 
  2. Remove old gaskets and left-over material from the exhaust manifold, the oil supply line and oil drain line flanges. Inspect these surfaces for cracks, flatness, or erosion. 
  3. Inspect the oil supply and drain lines for degradation and cracking.  
  4. Make sure that there are no kinks or any other type of restriction or clogging in either line.
