In the case after replace relief valve and the oil pressure would be low, what could be the problem? chain tensioners loosing oil? oil pump gears with excesive wear?
I have to mention that this hydraulic lifter noise started after the engine was repaired of water-oil mixed through one of the brass plugs in the cylinder head that was corroded.

I would two things: 1. Replace the pressure sender with a mechanical gauge and test the system again. If the problem persists, 2. I would next be looking at the oil pump itself for excessive wear or pitting on the gears.
