Engine Year of Manufacture by Engine Serial Number

Do any of you know of a way to determine a year or range of years in which a particular engine was built?

I have an `85 110 with a later 200TDI swap and I'd like to know when the engine was built. I've encountered no shortage of help in finding information to decode my truck's VIN, but looking up the year of manufacture for a particular engine is turning-out to be more difficult than I expected.

Glencoyne Engineering has been the most helpful source I've found to-date, but it only helped me determine the engine I now have was originally installed in a Defender (11L prefix).

I went through the same on mine. There actually are YoM stamps on the engine block, which are usually hard to see because they are covered by crud and obstructed by other engine bay components. Mine had them on the LH side and I have only been able to see them when I pulled the engine out and pressure-washed it. Other parts can usually give you an idea like oil cooling lines, for example, have YoM stamped on their metal rings (although these could have been replaced and, therefore, be "younger" than the engine). Other than that I couldn't find any way the "decode" the engine serial number to tell the YoM.
