Is this a new motor , old motor, was any work just done to it . More details needed.

this motor have 4 years of refubrished

OK if this motor has been running for 4 years when was the last time you changed the oil filter? Even if the car has sat for the last 4 years things go bad from just sitting. There is a old saying K.I.S.S.( Keep It Simple Stupid ) most guys will make a problem harder than it needs to be. No oil did you change the filter? I don't care if you put on on last week something may have happened to it , Put a new one on it and see what happens. What does the oil look like? If you changed it last week and it looked like mud you could be plugged up some place.

Cam bearing has turned in it's bore, cutting off the oil flow to the rocker arms..

I agree the cam brg is the most likely problem

I know this may be a simple question, but are you checking the pressure with the engine running, or just by priming the pump.  I like to start with the K.I.S.S.

Johny... creo que esto es lo que podria ser, las bocinas de el arbol de levas giraron y bloquearon el paso de aceite hacia arriba.

Para chequear eso, tendrias que desarmar las camaras ( sin desmontar las camaras ), quiero decir, quitar los martillos, para quitar luego los taquetes. Desarmar el frente del motor ( bomba de agua, compresor de aire, alternador, damper tapacadena, cadena de los tiempos, radiador ) para sacar el arbol de levas y revisar las bocinas a ver si estan movidas dentro del bloque.

I would suspect spun a cam bearing.

Did this engine overheat or just begin making a sound one day?

I think either way the motor should be taken apart and examined completely.
If you keep messing with it and taking guesses your solution will be an engine replacement.

 Nacho, ask him why he thinks he lost oil pressuer. Did the engine start to rattel?
