I think that y connector for the coolant breaking has a major roll in the head gasket failing - the head gets zero coolant flow when that piece breaks and just dumps it right onto the turbo exhaust manifolds not long to overheat the aluminum and break something
I didn’t pinpoint the knock and will have to wait until tear down to determine what the issue is the engine still runs and doesn’t throw codes yet so I think I should be ok to repair the engine
