'Basics boy, Basics'- Part 2

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.  

What does 2 minutes cost?

First: 
   On this, the first day of April, I wanna wish my wombmate, my sister Elizabeth, a very Happy Birthday.  You are loved more than you know Liz- heres hoping its a great day for ya!!  

    What can 2 minutes get ya?  Warm-ups part 1
  
    Well, to speak for the machines, let me clue ya in. We all have been told for years that every cold start on an engine is detrimental and does irreversible damage. Realistically, we can't much avoid that type of initial damage without pricey pre-oilers, but driving and loading a cold engine is far more damaging long term and quickly takes over as root cause of premature engine failure.
  
    Some of the damage is alleviated by using good oil, but loading a cold engine and cold oil cannot help but remove miles from the tail end of the engines life at a more rapid rate regardless. Define 'cold' you say. OK, so, some parts of the engine run very hot, some run cooler. When possible, everything under the hood should roughly half of its normal operating temperature before putting any load on the engine- 'rule of thumb' there if ya need one.
