If you ae talking abou the relief valve tha tis in the housing take it out and replace it if you like or take it get the crap out, but that hasn't much bearing on oil pressure that is controlled in pump. Has pump been modified? If anything your pump relief valve may be sticking causing the gasket to blow out. One thing to look for is to make sure all of gasket material is out of where oil filter adapter goes in as that is the number one cause of failure. It should also be a a squretype oring if memeory serves me right. It's like the old cartridge oil filters.
