I need help What could be causing my crank case oil contamination with diesel fuel. I have an international 3400 backup. Are there seals in the injector pump which could leak during operation?
 
You are correct. Seal on the input shaft is probably bad. Set the engine up on #1 TDC compression before taking things apart. Mark the distributor location to retain timing. JimN
