Based on the appearance of metal after 1,100 hours (filings in the
filter and doubling of FE content in 36 hour oil analysis), I'm having
my Lycoming o-360 taken apart. Two major choices to make:

1) Overhaul or 'look, see, fix'.
Your thoughts and opinions are valued.

When my IO-540 did that at about the same TSMOH, the fact that labor
costs to tear down and fix vs to O/H were the same impressed me. Only
thing that changes is parts cost.

At more than 50% time gone to TBO, I opted for OH.
