EM-79 ENGINE MECHANICAL (2JZ-GTE) - CYLINDER BLOCK EM0AP-02 INSPECTION 1. REMOVE GASKET MATERIAL Using a gasket scraper, remove all the gasket material from the cylinder block surface. 2. CLEAN CYLINDER BLOCK Using a soft brush and solvent, thoroughly clean the cylinder block. P02289 3. INSPECT CYLINDER BLOCK SURFACE FOR FLATNESS Using precision straight edge and feeler gauge, measure the surfaces of the cylinder block for warpage. Maximum warpage: 0.07 mm (0.0028 in.) If warpage is greater than maximum, replace the cylinder block. P02429 P02150 Z02380 4. INSPECT CYLINDER FOR VERTICAL SCRATCHES Visually check the cylinder for vertical scratches. If deep scratches are present, replace the cylinder block. P02286 5. INSPECT CYLINDER BORE DIAMETER Using a cylinder gauge, measure the cylinder bore diameter at positions A, B and C in the thrust and axial directions. Standard diameter: 86.000 - 86.013 mm (3.3858 - 3.3863 in.) Maximum diameter: 86.02 mm (3.3866 in.) If the diameter is greater than maximum, replace the cylinder block. 1 Thrust Direction Front 2 2 Axial Direction A 10 mm (0.39 in) B Middle C 10 mm (0.39 in) EM0086 EM2548 Z00145 1997 SUPRA (RM502U) Author : Date : 1184
