What engine are we dealing with? Briggs made several 5hp engines, some drastically different from others. Assuming this is a 130000 series, I'd say you need to pull the head and have a look at the piston (possibly hole in it) if it's building up that much pressure in the crankcase. If it's a newer OHV engine, it could also be a badly blown head gasket.
