Well, here is my experience. The HBV was my first ever job on the omega so I'm no expert. Like you I saw various posts that seem to contradict. The one that was most accurate was the one that said just remove the scuttle but be prepared for some knuckle rash!
This was how it went for me
remove the wipers (wipers took about an hour to remove and I had to use loads of releasing fluid and tools to prise them up as they hadn't been off for ages - they now come off in 2 minutes!). Remove the scuttle by undoing the half turn screws under the windscreens rubber sealing strip, plus there is a screw on the drivers side. There is a cable clipped under the scuttle that needs unclipping and a couple of rubber seals at each end. The scuttle can then be put to one side on the wing.
You will now have limited access to the HBV from the drivers side. The HBV is clipped on behind the engine in the same way that you clip a front light on a bicycle (check out the replacement HBV), it will be easier if you lift it off the clip next to allow it to come towards you. The task now is to remove the three water pipes and the vacuum tube. This is where you need patience and the plasters for your hands! To get the spring clips to open and move I found that a pair of hose clip pliers from halfrauds made the job much easier than trying to improvise. The whole job took me about 3 hours, but I was moving at super slow speed as it was all new territory.
Hope this helps. Good Luck.
