You will have to check the oil pressure and post the results, use a mechanical gauge and send the readings cold idle, hot idle and hot 1500RPM

Sorry your language must be local terms and means nothing to be, I need idle psi, idle hot psi, 1500rpm psi and that's all, in that order, if you cant post what I need I cant help you.
