Definitely would suspect the oil pump especially if it's aftermarket too, check the lash and shim the new one.. Also put OEM rods and mains in it so atleast the guy can make enough to rebuild it again with OEM parts when it eventually fails..

Thank you.. I really don’t like using it but that’s what they provided. I check oil pressure at the oil cooler before the oil filter and after n still the same .. I went on a road test with the gauge at the fitting before the oil filter n it still had the pressure drop some times . So I suspected a oil pump due to where I check the pressure at
