Could anyone explain the difference between the Isuzu
diesel 4LE1 and 4LE2. I was quoted on a
price for a 4LE2 4cyl 54 hp. Just looked at the
engine sticker which said the
engine I received is a 4LE1 NYBW-02 (No such model in the manual) but there is 4LE1 N. No reference to the rest of the model number. I want to have some background info before I contact the dealer. Many thanks...
