I overhauled my 284 and when i cranked it up, oil is pushing out between the head and block on the rear exhaust side. Any thoughts on what i did wrong? My eyesight is bad so maybe misinstalled head gasket?
Are you sure you had the correct gasket and that the block and head were both spotlessly clean before re-assembly? You didn't use any gasket sealer did you? Did you follow the correct torque sequence and torque to spec in stages?
