I have a 96 caprice completey cloned into a impala ss . Ik it’s not a implala but deal was to good to pass up . My oil pressure drops real low when motor is at operating temp . Cold start it’s a1 . I replaced the oil pressure sensor nd same thing . Could the sending unit be my problem? Someone help , also can’t find location of the oil pressure sending unit not a mechanic lol just tryna learn as I go .
