Maintenance/Repairs

2000 Nissan Frontier: Only when hot, engine knocks from center of engine on right bank. Not consistent, intermittent, goes away when revving above 3k rpms.
Ever since: Preventative maintenance was performed: Timing belt, oil pump, water pump, valves machined and re-seated, new guides.
Idle is smooth and slightly high on cold start up, no vacuum leaks seen. Manifold vacuum is only 15.5 to 16 in/hg, returning code of knock sensor (believe due to knocking). Not a rod knock, not a valve tap. Possible wrist pin noise? Any help is appreciated before I tear this thing back apart. Thank You!
