check the pcv , if its building crankcase presure that will be the first gasket to go.. alsol when you fit a new one dress the gasket with loctite 515 or 518 ,these are anerobic sealants and are prob the best avail. in a lot of instances i used to leave of te gasket completely and use only these sealants ( full custom l20b efi bluebird built for sprints racing) and never failed.
