What do you think this is?
You believe that you have a noisy hydraulic tappet on no. 5. That means that there's a large gap between the top of the valve stem and the camshaft lobe. The valve will therefore close normally won't it?
Your Delphi code reader identified no.5 as misfiring. Was the sparking plug black or wet to confirm this?
Also, in post no. 36 you described how the fault cleared after renewing the LH bank sparking plugs (odd, if it's a faulty tappet). Then, after renewing the plugs in the RH bank, the fault returned. Might it be possible that you have an intermittent electrical connection in the wiring to one or more of the coils?

Hang on a minute ... hadn't you used a stethoscope which indicated that the tapping noise was coming from the bellhousing?
