And see how old those fuel and oil hoses are. Ten years is the
outside limit, and five is more reasonable. They get brittle and crack
with age and can cause some serious second thought.
The oil filters should be checked after a couple of hours
running. Running the engines on the ground a few times puts a whole
lot of moisture into the case and causes acid formation and corrosion.
If the bearings/journals and pistons/rings have been roughed up by
corrosion there might be metal in the filters.

I plan on replacing all the hoses and such, again, as a preventative
maintanance type thing, it's a bit more cost for quite a bit of insurance in
my line of thinking, plus if I get it done now, it shouldn't be an issue for
the next few years.

On ground running the engines. I thought that as long as you ran them on the
ground long enough to get them up to operating temperature then it wasn't a
problem? Something about getting the oil hot enough to evaporate the water
or something. Is this just simply incorrect information?
