At about 185,000 mi. I developed an intermittent clatter sound in the engine that has been running Mobil Synthetic oil since 75,000 mi. and at 192,0000 changed out the rocker shafts and rocker arms, as several people thought that the clatter was a result of bad lifters (tappets) or worn shafts and or rocker arms. The sound persists but is not noticeable at startup, when, I assume the oil is thicker. I am considering the possibility that the problem is the oil pump. Any thoughts?
