Sure, but if there's a leak you have a problem.

Based on the anecdote from peterburkimsher below, and not seeing any other reason to vent the pressure, I would guess so.

Sounds like .. there's a leak.

You'll leak somewhere. Everyone does.

so if I block it with my finger from takeoff to cruise I can create a little explosion? Or is the issue the repeated cycles of pressure weakening the material over time?

It's like a pipe that is 99.9% free of leaks. It's still leaking!

isn't the worst case it goes into the engine and it explodes/burns?

Might be over-pressure due to the bursting open of the fuel.

For now, I think the gas escaping is preventing water from rushing in.

A leak at 400 atmospheres doesn't stay a leak.
