I have tried both the OEM cast and a chrome aftermarket style like the one below. I have sanded off the chrome, tried different sealers, even tried the Right Stuff gasket maker...still leaks. Has anyone used the O-ring style or a billet aluminum type? If so, how well do they seal? I'm running an oem iron water pump housing. Do the new aluminum housings seal better? Thanks in advance!!
