I don't think any filter will help ENOUGH, as the debris is created in several
areas. The worst place is inside the cam cavity. Hammering, cavitation, etc
Rick confirmed that to me when he reported back that the piston bottom that
rides on the cam follower was hammered
That would have the potential of debris floating inside the cam cavity. That would
then have the potential of screwing up the DLC surfaces or any mating surfaces.
Down stream through the intake for the piston/cylinder will have this stuff and
then into the distribution system to the injectors
Return lines abound in this system and yes, a filter in any one of these return
runs can't hurt, but think they won't save it, as the cam cavity is the
source of the debris, IMHO
I'm not sold on the time of year, other than that is when folks crawl out of
the winter dull-drums and go camping clocking many, many more miles.
Think that winter storage also has the heat/cool cycles to condense any moisture
in the diesel system to then create ideal conditions for H2O damage (cavitation
is my main thought)
