schlackoff, it is obvious you have no idea what is involved in "tearing down"
an engine.


Huh? the diesel engine on a commercial fishing vessel is torn down the
night
before sailing to effect a major overhaul? And is torn down and overhauled
by
drunken, nervous crew?

Those are your words, not mine. I said that often (not always) the
engineer will do a teardown while in port between extended trips at sea
to check the engine. It might not need a major overhaul. That doesn't
mean it won't be checked.
