Hi mate from the oil pump side look towards the left and you,ll see a round plate with about (8) m12 bolts in it,take that off and on it is a oil pressure relief valve,and micro oil filter ,check them first ,because if the micro oil filter gets blocked it produces no pressure,any problems let me know and i,ll help more
