You have omitted the first block of numbers, David. There is a 6 digit block of numbers called the model number that comes before the 0169-01, which is the type number, and the 85011010, which is the manufacturing date and assembly line number, called the code number. In case it is useful, your engine was manufactured on 10 January 1985, but that is as far as we can get without the model number.
