You said you verified by the valves being closed.. but that is not particularly accurate...
Did you stick an extended dial indicator on the top of the ( or even A ) piston .. mark spots evenly on both coming up and going down.. then split that difference to determine Actual TDC ? In other words... you are assuming the pulley is not rotated on the crank ?

this would be difficult to accomplish with a IDI diesel... you'd have to pull the prechambers.
