    NOTE:
    NOTE:
    • Always use the new turbo manifold module gasket.
    • Always use the new turbo manifold module nuts.
    • Take care whether the oil feed pipe & hose assembly is interfered with turbo manifold module and any surrounding parts.
    • If the oil feed pipe & hose is damaged, engine oil is not supplied sufficiently to the turbocharger then it may damage the turbocharger. If the oil drain pipe & hose is damaged and clogged, engine oil is not drained smoothly then it may cause oil leaks from the turbocharger. Be care full the oil feed pipe & hose not to damage (Bent, crushed, torn or cracked).
    • When installing, replace with a new gasket. When installing the turbo manifold module, tighten the nuts with pre-torque first, and then tighten the nuts with specified torque in the sequence shown.
