    Sabi sakin ng mechanic my singaw daw sa Exhaust Manifold ko, kaya medyo hirap talaga ako sa hatakan. Parang naririnig ko kasi after ko bumitaw sa 5th gear, my air leak ako naririnig sa pipes or sa exhaust. may possibilities po ba na kaya medyo hirap sa hatakan and malakas sa gas is because there are some leak in ExhaustManifold? Nahihinang or narerepair po ba mga ito?

    Ride: Sentra B13

    Thanks Tsikot

    Depends on where the leak/crack is located.

    If its the exhaust gasket, a simple replacement job would fix it.

    If it's the stock exhaust manifold, you will have to replace it because you cannot weld cast iron. Your choices would be a surplus stock exhaust manifold or a set of headers.

    Sir, possibilities po ba ng may leag ang Exhaust Manifold is Hirap Humatak and malakas sa Gas Consumption?! Ang lakas kasi ng air leak na naririnig ko.

    Yes... the leak caused back pressure to be reduced resulting in less power and poorer fuel economy.

    Thank You very much sir sa paglilinaw! Now I know na talaga na my problem of hard sa power and high fuel consumption is the leak on my Exhaust Manifold.. Patingin ko na lang sir sa mga Muffler.
