A Puzzle: Engine seems to be running rich or burning oil but has good compression

[ndutton]

The next day I adjusted the oil pressure in two turns and cold I went from 40PSi to 50PSI. I then changed the oil with Rotella 15W40 (the previous owner was running Delo 400 30W) and when I pulled the 3.75 quarts out... the oil had a gas smell to it.

Gas smell in the oil is the typical symptom of a ruptured fuel pump diaphragm. If you have a mechanical pump, a rebuild is indicated.

The mechanical is long gone and a MM Faucet now feeds the motor. So the mystery still persists.
