REMOVE ENGINE HANGERS AND GROUND STRAP 2. REMOVE CAMSHAFT POSITION SENSORS 3. REMOVE EGR COOLER P12293 4. REMOVE VALVE LIFTERS AND SHIMS HINT: Store the valve lifters and shims in correct order. P02267 5. REMOVE VALVES (a) Using SST, compress the valve spring and remove the 2 keepers. SST 09202-70020 (09202-00010) (b) Remove the spring retainer, valve spring, valve and spring seat. HINT: Store the valves, valve springs, spring seats and spring retain- SST P12308 ers in correct order. (c) Using needle-nose pliers, remove the oil seal. 1997 SUPRA (RM502U) Author: Date: 1139 EM-35 ENGINE MECHANICAL (2JZ-GTE) - CYLINDER HEAD EM0AJ-02 INSPECTION 1. CLEAN TOP SURFACES OF PISTONS AND CYL- INDER BLOCK (a) Turn the crankshaft, and bring each piston to top dead center (TDC). Using a gasket scraper, remove all the car- bon from the piston top surface. P02137 (b) Using a gasket scraper, remove all the gasket material from the top surface of the cylinder block. (c) Using compressed air, blow carbon and oil from the bolt holes. CAUTION: Protect your eyes when using high pressure-compressed air. P02110 2. REMOVE GASKET MATERIAL Using a gasket scraper, remove all the gasket material from the cylinder block surface. NOTICE: Be careful not to scratch the cylinder block contact sur- face. P02131 3. CLEAN COMBUSTION CHAMBERS Using a wire brush, remove all the carbon from the combustion chambers. NOTICE: Be careful not to scratch the cylinder block contact sur- face. P02128 4. CLEAN VALVE GUIDE BUSHINGS Using a valve guide bushing brush and solvent, clean all the guide bushings. P02072 1997 SUPRA (RM502U) Author: Date: 1140 EM-36 ENGINE MECHANICAL (2JZ-GTE) - CYLINDER HEAD 5. CLEAN CYLINDER HEAD Using a soft brush and solvent, thoroughly clean the cylinder head. P02129 6. INSPECT FOR FLATNESS Using precision straight edge and feeler gauge, measure the surfaces contacting the cylinder block, intake and exhaust manifolds for warpage. Maximum warpage: 0.10 mm (0.0039 in.) If warpage is greater than maximum, replace the cylinder head. Z09528 7. INSPECT FOR CRACKS Using a dye penetrant, check the combustion chamber, intake ports, exhaust ports and cylinder block surface for cracks. If cracked, replace the cylinder head. P02136 8. CLEAN VALVES (a) Using a gasket scraper, chip off any carbon from the valve head. (b) Using a wire brush, thoroughly clean the valve. EM0580 1997 SUPRA (RM502U) Author: Date: 1141 EM-37 ENGINE MECHANICAL (2JZ-GTE) - CYLINDER HEAD 9. INSPECT VALVE STEMS AND GUIDE BUSHINGS (a) Using a caliper gauge, measure the inside diameter of the guide bushing. Bushing inside diameter: 6.010 - 6.030 mm (0.2366 - 0.2374 in.) Z02413 (b) Using a micrometer, measure the diameter of the valve stem. Valve stem diameter: Intake 5.970 - 5.985 mm (0.2350 - 0.2356 in.) Exhaust 5.965 - 5.980 mm (0.2348 - 0.2354 in.) (c) Subtract the valve stem diameter measurement from the guide bushing inside diameter measurement. Standard oil clearance: Z00052 Intake 0.025 - 0.060 mm (0.0010 - 0.0024 in.) Exhaust 0.030 - 0.065 mm (0.0012 - 0.0026 in.) Maximum oil clearance: Intake 0.08 mm (0.0031 in.) Exhaust 0.10 mm (0.0039 in.) If the clearance is greater than maximum, replace the valve and guide bushing. 10. INSPECT AND GRIND VALVES (a) Grind the valve enough to remove pits and carbon. (b) Check that the valve is ground to the correct valve face angle. Valve face angle: 44.5° 44.5° Z00054 (c) Check the valve head margin thickness. Standard margin thickness: 0.8 - 1.2 mm (0.031 - 0.047 in.) Minimum margin thickness: 0.5 mm (0.020 in.) If the margin thickness is less than minimum, replace the valve. Margin Thickness EM0181 1997 SUPRA (RM502U) Author: Date: 1142 EM-38 ENGINE MECHANICAL (2JZ-GTE) - CYLINDER HEAD (d) Check the valve overall length. Standard overall length: Intake 98.29 - 98.79 mm (3.8697 - 3.8894 in.) Exhaust 98.84 - 99.34 mm (3.8913 - 3.9110 in.) Overall Length Minimum overall length: Intake 98.19 mm (3.8657 in.) Exhaust 98.74 mm (3.8874 in.) If the overall length is less than minimum, replace the valve. EM2534 (e) Check the surface of the valve stem tip for wear. If the valve stem tip is worn, resurface the tip with a grinder or replace the valve. NOTICE: Do not grind off more than the minimum overall length. EM0255 11. INSPECT AND CLEAN VALVE SEATS 45° (a) Using a 45° carbide cutter, resurface the valve seats. Carbide Cutter Remove only enough metal to clean the seats. P02127 (b) Check the valve seating position. Apply a thin coat of prussian blue (or white lead) to the valve face. Lightly press the valve against the seat. Do not rotate the valve. (c) Check the valve face and seat for the following: Width S If blue appears 360° around the face, the valve is concentric.
