oil filter blew off two times pressure is 70 to 80 on the high side

IF the filter blew 'OFF' and is still intact without apparent damage .. It's the WRONG filter!!!!! IF the filter has been damaged due to high pressure, split or burst open... Oil pump pressure relief valve is sticking!!! To help solve this problem... Post the oil filter brand and part number, I'll check it out, IF you really want to know that is!!!!!... If no reply, I'll assume it's the wrong part!
