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?

No, your rebuilder should have it. May be 10 hours or so.

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?

I think you're speaking of the case bolts. The through bolts go all
the way through the case near the cylinder bases. If the case bolts
weren't done properly, there's no reason to believe the through bolts
were, either.

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.

You'll not see anything special on the engine analyzer. Ask if they
retorqued the cylinders and through bolts. Not a hard job, but very
time consuming removing all the junk around the engine.

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

What do you mean by "if wet"?

Signs of further leakage.

Thanks,

Stay safe, I may need a room one day!
