Oil leak on top of the engine

There are bolts that should have been retorqued at a certain hour.
The shop would have specified which ones.

No one I've talked to has heard of this schedule with regard to the case
bolts. Have you got a Lycoming reference for this?

Understand this. If the case is fretting, as it does when bolts are
loose, it's a very serious situation. If this were my engine, I would
have another mechanic check the torque of the through bolts.

What are the "through bolts"? Are these the bolts I'm talking about, or
different ones?

Do Not Fly This Airplane.

Too late. We torqued everything to spec, and flew it uneventfully for half
an hour, at all throttle settings, at altitudes up to 4000 feet. No leakage
noted, all six bars on the JPI engine analyzer looked fine, everything
sounded and ran perfectly.

If wet,
the engine needs to be pulled and the disassembled, cases sent out and
reassembled.

What do you mean by "if wet"?

Thanks,
