Remove the cylinder head assembly. The cylinder head bolts should be removed using Special Tool, Cylinder Head Bolt Wrench (09221-21000), in the sequence as shown in the illustration. 16. Remove the gasket pieces from the cylinder block top surface and cylinder head bottom surface. NOTE: 1. Make sure that the gasket pieces do not fall in to the engine. INSPECTION 1. Check the cylinder head for cracks, damage and coolant leakage. 2. Remove scale, sealing compound and carbon deposits completely. After cleaning oil passages, apply compressed air to make certain that the passages are not clogged. 3. Check the cylinder head surface for flatness using a straight edge in the direction of A, B, …as shown. If flatness exceeds service limit in any direction, replace the cylinder head, or lightly machine the cylinder head surface. Cylinder head flatness Standard value: Less than 0.03 mm (0.0012 inch) Limit: 0.08 mm (0.0031 inch) REASSEMBLY 1. Clean all gasket surfaces of the cylinder block and the cylinder head. 2.
