Head gasket or oil cooler/ filter housing. I have the same problem and have not taken the time to find it yet.

Injection pump has an external oil line to it, very leak prone. Aircompressor has an eaxternal line to it and large gasket area for oil return to bloxk, somewhat leak prone. Valve rocker cover gaskets can leak some times. Generally if you blew a head gasket, you will know it. JT Happy New Years too.
