Toyota Corolla 1.6 GLI Lights me oil light

The car has the oil at the level but after about 20 minutes it lights the oil precion light and sometimes and heard that makes a sound like cli cli I think they are what calls buses or valves. In my little experience I am a mechanic but I dedicate my sales to sales.

Practically, when it reaches the operating temperature, it turns on, by logic it must be that the pump has mismatches and loses the pressure, it can be dirt in Tama, or oil strainer in the carter, it is necessary to disassemble the carter to change the pump or to clean the size. Good luck that you break yourself.

Thank you very much I tell you about 80 km to the piece that you call you tamal we tell you Pichacha in Guatemala and it followed me with the problem then I lean to change the bomb thank you very much I tell you if I manage to solve it.
