Pointless question. Insufficient data for any kind of decision.
Presumably, you'd preflight the aircraft anyway, which obviates your above
question.

Not really. For me, the question is do I bother making the trip to the
airport, or do I wait for someone else to be the "canary in a cage". I've
also got a slightly nervous a passenger to consider - last thing I want is
an engine fire with a nervous passenger sitting right next to it.

The crux of the question really is "if the licenced and qualified engineer -
who would get paid for fixing the problem if there was a problem - says that
it's OK, does one trust that? As a pilot I won't be able to see where the
leak is coming from without removing the cowling - which is engineer only
territory.

Part 2 of the question is "why would full tanks cause this - why wouldn't
the excess get squeezed out the tank vents"?
