cutting filters
while cutting open filters is an important part of a maintenance program it is a relatively crude engine condition monitoring tool but oil spectro analysis will detect a cam shaft problem long before metal is found in the filter.
in the case outlined above the Fe level on the second oil analysis will not fall, in all probability the Fe level will rise rapidly.
before taking a single engine across a lot of water I would want to see the Fe level at the second oil analysis fall, if it did not do so the first thing I would do is pull a front cylinder and get a good look at the cam shaft, the front cams being the most likely suspects.
