The inspection had thus begun in the mystery of the smokey diesel.
Here comes part 2.
After dismantling the valve assembly, the first thing I noticed was heat damage on the intake side rocker arm assembly- discoloration of the metal and ground-down sharp edges on the rocker arm and the thrust washer that holds it on the shaft and no oily feel to the parts at all. Eek, the rocker arm and its associated parts had not gotten any lube- not good.
