This sets cylinder No. 1 to TDC on compression stroke. Cylinder No. 1 is front cylinder on right side when viewed from rear of engine. (Scheme 49)
4. Ensure intake and exhaust valve lifters on cylinder No. 1 are loose. If conditions are not as described, rotate crankshaft clockwise one complete revolution.
5. Using feeler gauge, measure and record valve clearance between valve lifter and camshaft on intake valves of cylinders No. 1 and 6 and exhaust valves on cylinders No. 2 and 3. (Scheme 49)
6. Rotate crankshaft clockwise an additional 2/3 turn (240 degrees). Measure and record valve clearance between valve lifter and camshaft on intake valves of cylinders No. 2 and 3 and exhaust valves on cylinders No. 4 and 5. (Scheme 49)
7. Rotate crankshaft clockwise an additional 2/3 turn (240 degrees). Measure and record valve clearance between valve lifter and camshaft on intake valves of cylinders No. 4 and 5 and exhaust valves on cylinders No. 1 and 6. (Scheme 49)
8. To determine if valve clearances are within specification, see «VALVE CLEARANCE SPECIFICATIONS»(/toyota/camry-solara/i-1998-2003/remont/mechanical/#engine-mechanical-30l-v6) table. VALVE CLEARANCE SPECIFICATIONS Application (1) In. (mm) Exhaust Valve.010-.014 (.25-.35) Intake Valve.006-.010 (.15-.25) (1) Adjust valve clearance with engine cold.
9. If valve clearance requires adjustment, rotate camshaft so lobe on valve to be adjusted is facing upward, away from valve lifter. Position notch on valve lifter perpendicular to the camshaft. Ensure notch is not aligned with the camshaft. Valve Clearance Adjuster (SST 09248-55040) is used to remove adjusting shim. Using SST "A" of valve clearance adjuster, push downward on valve lifter. (Scheme 50)
10. Place SST "B" between camshaft and valve lifter with the side marked with a "7" or "9" in the right location, depending on cylinder application. Side marked with "7" should be used on front valves on No. 1 and 2 cylinders only. Remove SST "A".
11. Using small screwdriver and magnet, remove adjusting shim. Measure and record thickness of removed adjusting shim. Using measured clearance and adjusting shim thickness, select proper replacement adjusting shim. (Scheme 51)and (Scheme 52).
12. Install replacement adjusting shim with imprinted number on adjusting shim facing the valve lifter. Recheck valve clearance. Before installing valve cover and gasket, apply sealant at front and rear areas of cylinder head. (Scheme 53)
13. Using NEW gasket, install valve cover. Install and tighten valve cover bolts to specification in several steps. See «TORQUE SPECIFICATIONS»(/toyota/camry-solara/i-1998-2003/remont/mechanical/#engine-mechanical-30l-v6__torque-specifications). To install remaining components, reverse removal procedure.
