ENGINE 273 MPFI 107 ENGINE Sr. Item Specified Limit of Value (in mm) distortion (in mm) 1. Distortion of 0.02 0.05 gasket surface Leakage of combustion gases from this gasketed joint is often due to warped gasketed surface; such leakage results in reduced power output and hence a higher cost of fuel per kilometer. NOTE Cylinder head top surface machining is not permitted. Distortion of manifold seating faces : Check the seating faces of cylinder head for manifolds, using a straightedge and thickness gauge, in order to determine whether these faces should be corrected or the cylinder head re placed. Sr. Item Specified Limit of Value distortion (in mm) (in mm) 1. Exhaust manifold 0.03 0.1 seating surface 2. Intake manifold 0.03 0.1 seating surface Cylinder head cover: Remove the baffle plate in the cylinder head cover by removing the screws. Check the baffle plate gasket, if it is torn/damage replaces it; otherwise it might result in high engine oil consumption. Check the condition of cylinder head cover gasket. Replace if required. Before opening cylinder head cover baffle plate, check for leakage @ 0.2 bar air pressure.
