The little plastic pieces may be the remains of the valve stem 
"seals". These commonly show up in the sump and are not really a 
concern. I agree that times like this are a good time for a short oil 
change cycle, maybe 500 miles.

I've never seen one of the sump magnets, but I'd stick with the OE 
screen. The replacement ones don't always give me the same degree of 
confidence. The only problem I see with old ones is that the 6 bolt 
holes tend to get distorted so they stick on the studs. You can fix 
this easily with a tapered reamer. Just remove a LITTLE bit of 
material, and clean the chips out of the strainer before you 
reinstall it.

Not long.

Inner tubes are made of butyl rubber because butyl is less permeable 
to air. OTOH, butyl rubber is incompatable with oil, so you will see 
the results in a few days as the tube swells up to about double size.

I have some good rubber filler tubes.
