Hello there I had a question hopefully can get a thorough answer on what the cause is? So, a small hose that connects to the intake manifold and connects to bottom of the bpt valve is shooting out hot high pressure, and keeps blowing off the hose from bottom of the bpt valve. I understand it's supposed to blow from intake manifold through the bpt valve then through egr valve. With recently removing the engine and completely cleaning it up, changing gaskets, new exhaust system, seals, water pump, new plugs and wires basically an overhaul. I never really noticed before the overhaul if that much pressure was coming out of the intake manifold. Is it just a bad bpt valve that's not allowing high pressure from the intake manifold to travel through bpt valve correctly? What could be causing that much pressure to continue blowing off the small hose from bottom the of the bpt valve? And is that much pressure supposed to be coming from the intake manifold through that small of a rubber hose? It's a stock Hitachi rebuilt carb, all stock motor 2.4 but in process of cleaning up air the lines, and maybe deleting unnecessary hoses for emissions. Thanks
