The PS hoses appear to leak under load, however the aerodynamics of the air flow around this part and the placement of this part on the engine creates a wide distribution of the fluid, the exhaust manifold as well as the exhaust connection to the muffler system is close to this area this creates a fire hazard.
Bad engine design.
