Ford Ranger Thailandesa 2006 without oil pressure

Holy to all

good the issue is that I have a Ford Ranger year 2006 Thailandesa with adjusted engine resien. And when
the oil light starts it, the oil pressure meter was put and the oil filter is removed and the same is given, the same with the vulvo, and the oil pump is new. The doubt is that by disarming before adjusting, I had the 2 damaged compensating axes, and it goes with buses that were not for sale,

the question is that it can be that for the compensators is losing oil pressure?

Oq another test can be done
