Your first mechanic is an idiot but he is going to give you the shaft
for HIS error.
There is some difference in the break away torque of a bolt that has
sat with a preload on it and one that you are tightening to a
specified torque. It takes MORE torque than that specified to start
the nut turning if that nut has sat with a preload for more than a
second. You can be assured that if the nut turns when the specified
torque is applied then it is NOT torqued to the specified amount and
needs to be loosened and retorqued.

The most common cause of cylinder bolts getting loose is PAINT or dirt
under the cylinder flange.

These bolts are critical and must have the required torque.

If you loosen only one nut at a time you should not have to replace
the seal but if you loosen all of the nuts at the same time then there
is a good chance that it will leak because the cylinder will move.

Should you just tighten it to thee correct torque, or should the others be
loosened then all tightened in sequence? Maybe even replacing the
gasket?

The first mech. I talked to was adamant. It was his butt on the line
liability wise, and if I wanted him to do the job, he was going to
break all the nuts and retorque everything, estimating 8-10 hrs labor.
He also mentioned a "one time seal" that would then likely be a leak
candidate as a result, but he wasn't going to do it any other way.
