Exhaust Manifold

CLEAN AND INSPECT
1. Discard gasket and clean all gasket surfaces of manifolds and cylinder head.
2. Test manifold gasket surfaces for flatness with straight edge. Surface must be flat within 0.15 mm per 300 mm (0.006 in. per foot) of manifold length.
3. Inspect manifolds for cracks or distortion. Replace manifold if necessary.
