Look pretty serious. Failure would be a catastrophic event.

Potential issue:
A hole has been drilled out of specification in the high-pressure port, leaving a wall thickness in a vulnerable state. An uncontrollable free flow of the second stage could occur if this thin wall section should rupture under pressure. A pressure test has proved that an affected body will not rupture during a dive, however, we cannot guarantee this in the long term.

Lots of regulators were affected, based on the serial number ranges. It's good to see a manufacturer doing the right thing in replacing them.

Mk10 with an internal crack ... how, why, WTH?

I was looking through my box of reg odds and ends and came across a Mk10. No idea where i got it but on closer inspection it may be toast. Any guesses as to what happened to cause such damage on the HP side?

See thread above. The tolerance for an over-bored HP port is pretty small. The reg body is very thin at the base of the port.

But it actually shouldn't be a problem unless the HP hose ruptured afterward. Any split that occurs in the body on initial pressurization is contained by the HP hose end. Tank pressure is easily within the limits of the HP hose and gauge.
