Received this aircraft in ZZZ; where the Local Maintenance told me the #3 Bleed HP Valve had to be secured shut because the wire going to the switch that operates it was faulty. In cruise from ZZZ to ZZZ1; we got a bleed 3 advisory message; ran the appropriate QRH procedure and landed without incident. Upon arrival to ZZZ1; we wrote it up and figured it was associated with the HP valve. The message was cleared and eventually we left for ZZZ2. During climb out; once again the message reappeared; and this time when we ran the procedure it was determined we would not have anti-ice on the #3 engine. We had not yet coasted out; so I contacted Dispatch and Maintenance via SATCOM so we could figure out what the best course of action would be. After an extensive discussion; weather analysis and input from Captain. It was determined we would be ok to continue to ZZZ2. This was a very time; resource and energy consuming situation which in my view could have been easily handled if we had just nipped it in the bud. This aircraft was being routed ZZZ-ZZZ1-ZZZ2-ZZZ3-ZZZ4; where in ZZZ4 it is going in for a C Check. I feel there was the feeling of just pushing it to get it to ZZZ4 where the issues would be resolved at the check. In the end; the Aircraft ended up being delayed in ZZZ2 for this and other issues which came to light during our flight to ZZZ2.
B747 Captain reported repeat issues with an engine bleed valve that impact the engine anti-ice system.
