I am not perfect, nobody is. I don't know why it is that when somebody posts many times and one or two of them don't come across perfectly right that some get defensive.

I do believe that the compression test thru the injectors is a better way because it removes the risk of breaking a glow plug. There are threads about broken glow plugs, but I am not familiar with any regarding broken injectors. The shop manual describes two ways and pictures one. Since then they may have updated their internal procedures thru programmed repairs or modifications or TSBs. The shop manuals are great but they are neither perfect nor completely current. I blend the advise of the manual, mechanics, and foreman whenever possible. Also, I have never heard of a cold compression test that had any meaning. I don't claim to know everything & am open to correction.
