diesel winterization questions

This question is for a 1GM10 raw water cooled.
  1. In researching winterization process steps, there is one step where there is differing opinion.
    1. The Yanmar manual states to remove fuel injector valve and put 2cc of oil and hand turn engine as.
    2. The Clymer manual doesn't even state to do this in their winter lay up section.
    3. The website - a fairly extensive website operated by a yanmar technician i the UK (i think) recommends spraying CRC into the air filter.
Any thoughts on above appreciated.

2. If you run a bucket of pink antifreeze (ethyl glycol i guess) thru the engine on it is on the hard, is it still necessary to drain the engine block?
