Why the rebuilds?

[Gregory OConnor]

Tin is in the bearings, iron is in the sleves and valves. If excess
iron or alumnium, I would look at the fuel ????? Did they say how
the fuels could fill your test with tin? I would send in the oil
filter if you have concern. the larger particles dont show up in
oilsample tests. I dont do oil sampling because the news is never
good. Its like looking out at the street to see if your car is stolen
yet.
