4176mack Posted March 2, 2013 Share Posted March 2, 2013 Hi folks.Iv'e been working out the engine I.D number on my 76 F series, ETAB 676 B, not a problem as the information is avalable to make it pretty straight forward to work out what the numbers and letters stand for, but I'm not sure about the last letter in the line up which is the letter 'B', the engine in my truck has got 3 oil filters fitted, could this be it ?, could it mean an E.S.I or E.S.I plus ?.Any thoughts wll be welcomed.
