REPAIR PROCEDURE: VALVE ROTATION: 1. Relieve the fuel pressure. Refer to the detailed service information available in TechCONNECTunder: Service Info>14-Fuel System>Fuel Delivery >Standard Procedure>Fuel System Pressure Release Procedure. 2. Remove upper intake manifold. Refer to the detailed service information available in TechCONNECTunder: Service Info >9-Engine>Manifolds>Intake Manifold> Removal. 3. Remove cylinder head cover(s). Refer to the detailed service information available in TechCONNECTunder: Service Info >9-Engine>Cylinder Head>Cylinder Head Cover(s) >Removal. 4. Remove rocker arm and shaft assembly. Refer to the detailed service information available in TechCONNECT under: Service Info >9-Engine>Cylinder Head> Rocker Arm/Adjuster Assembly >Removal). 5. Clean and mark the tip of each exhaust valve stem at the 12 O’clock position witha paint marker. The paint mark will be used later to assist with determining the amount of valve rotation. 6. Remove the sparkplugs. 7. Rotate the crankshaft clockwise, until the number 1 piston is at Top Dead Center (TDC) on the compression stroke. 8. Install the compression tester sparkplug adapter in cylinder#1 sparkplug hole. With air hose attached to sparkplug adapter, apply 620.5 to 689 kPa (90 to 100 psi) air pressure. This is to hold valves into place while servicing components. 9. Using Tool MD 998772A (1) with adapter 6527 (4) or equivalent, slightly compress the exhaust valve spring to release tension against the valve and valve spring retainer ( Fig. 1 ). 10. Remove the valve spring retainer locks and discard the locks. NOTE: It is important that the valve rotation section of this repair procedure be performed.

Removal 1. Disconnect negative battery cable. Raise and support vehicle. Drain engine oil. Remove right front wheel and splash shield. Put a block of wood between cradle and engine torque strut at bottom front end of engine. See Fig. 2 . 2. Remove mount from upper front end of engine, allowing engine to rest on wood block. Remove accessory drive belt and tensioner. Remove accessory belt idler. Remove cylinder head cover. 3. Replace silicone isolators on cylinder head cover screws if deteriorated. Remove power steering pump (leave hoses attached). Remove A/C compressor (leave hoses attached). Raise and support vehicle. Drain engine oil. Remove right front wheel and splash shield. 4. Remove support bracket between intake manifold and engine block. Remove front balancer/pulley using a 3-jaw puller. Disconnect exhaust pipe from exhaust manifold. Install Crankshaft Gear Retainer (SA9104E) onto end of crankshaft, with flat side toward crankshaft gear (sprocket). Crankshaft gear retainer holds crankshaft gear in place during removal of front cover. 5. Remove 4 bolts from front end of oil pan. Using RTV Cutter (SA9123E), cut RTV sealant between oil pan and front cover. Spray penetrating oil onto front cover dowel pins. Remove front cover bolts (one bolt is located above accessory drive belt pulley). Pry front cover from engine block. 6. To prevent pistons from hitting valves, turn crankshaft 90 degrees clockwise as viewed from front of engine until timing mark and keyway are aligned with split line of main bearing cap. Remove timing chain tensioner, guides and chain. While using a 7/8″ (21 mm) wrench to keep camshaft(s) from turning, remove camshaft sprocket bolt(s). Remove camshaft sprocket(s). Installation 1. To prevent pistons from hitting valves, ensure timing mark and keyway on crankshaft are aligned with split line of main bearing cap. Install camshaft sprocket(s) with the letters FRT (front) facing away from cylinder head. Use a 7/8″ (21 mm) wrench to keep camshaft(s) from turning. 2. Install and tighten camshaft sprocket bolt(s) to specification. Rotate camshaft(s) until a 3/16″ (4.8 mm) drill bit can be inserted through timing pin hole(s) and into cylinder head. See Fig. 5 or Fig. 6 . 3. Rotate crankshaft counterclockwise as viewed from front of engine until timing marks at crankshaft sprocket are aligned. Install timing chain, aligning Silver-plated chain links with timing mark(s) on camshaft sprocket(s) and bottom tooth (or teeth) of crankshaft sprocket. See Fig. 5 or Fig. 6 . 4. Install fixed chain guide. Slack part of chain should be on tensioner side of cylinder block. Chain should be tight against fixed chain guide. Install pivoting chain guide. Retract tensioner plunger, and pin ratchet

1. Remove the cylinder head cover. 2. Set No.1 piston at TDC . “UP” mark on the camshaft pulley should be at top, and TDC grooves on the camshaft pulley should align with cylinder head surface. 3. Adjust valves on No.1 cylinder. Intake: 0.26 mm ±0.02 mm (0.010 in) ± (0.0008 in) 0.30 mm ±0.02 mm (0.012 in) ±(0.0008 in) 4. Loosen the locknut, and turn the adjusting screw until the feeler gauge slides back and forth with a slight amount of drag. 5. Tighten the locknut and check clearance again. Repeat adjustment if necessary. 6. Rotate crankshaft 180° counterclockwise (Camshaft pulley turns 90°) . The “UP” mark should be on the exhaust side. Adjust valves on No.3 cylinder 7. Rotate crankshaft 180° counterclockwise to bring No.4 piston to TDC . Both TDC grooves are once again visible. Adjust valves on No.4 cylinder

1) Disconnect PCV hose, necessary electrical connections and spark plug wires to access valve cover. Remove nuts, seal washers, valve cover and gasket. 2) Rotate crankshaft clockwise so cylinder No. 1 is at TDC on compression stroke. Cylinder No. 1 is front cylinder at timing belt end of engine. Ensure timing mark on crankshaft pulley aligns with “0″ mark on timing belt cover. 3) Ensure valve lifters on cylinder No. 1 are loose and valve lifters on cylinder No. 4 are tight. If conditions are not as described, rotate crankshaft clockwise one complete revolution (360 degrees). 4) Using feeler gauge, measure valve clearance between valve lifter and camshaft on intake valves of cylinders No. 1 and 2, and exhaust valves of cylinders No. 1 and 3. Record valve clearance. Rotate crankshaft clockwise one complete revolution (360 degrees). 5) Measure and record valve clearance on intake valves of cylinders No. 3 and 4, and exhaust valves of cylinders No. 2 and 4. Ensure valve clearance is within specification. See VALVE CLEARANCE SPECIFICATIONS table. VALVE CLEARANCE SPECIFICATIONS TABLE (1) Application In. (mm) Exhaust Valve ………….. .012-.016 (.31-.41) Intake Valve …………… .006-.010 (.15-.25) (1) – Adjust valve clearance with engine cold. 6) If valve clearance requires adjustment, rotate camshaft so lobe on valve to be adjusted is facing upward, away from valve lifter. Position notch area on valve lifter toward inside of cylinder head. DO NOT align notch area with camshaft. Use Valve Clearance Adjuster (SST 09248-55040) to adjust valve clearance. 7) Using SST “A” of valve clearance adjuster, push downward on valve lifter. Place SST “B” between camshaft and valve lifter. See Fig. 2. Ensure enough clearance exists for adjusting shim removal. Remove SST “A”. Fig. 2: Adjusting Valve Clearance Courtesy of Toyota Motor Sales, U.S.A., Inc. 8) Using small screwdriver and magnet, remove adjusting shim. Measure and record thickness of removed shim. Using measured clearance and adjusting shim thickness, select proper replacement adjusting shim. See Figs. 4 and 5. 9) Install replacement adjusting shim. Recheck valve clearance. Apply sealant at indicated valve cover sealing areas on cylinder head. See Fig. 3. 10) Using NEW gasket, install valve cover and sealing washers. Install and tighten nuts to specification. See TORQUE SPECIFICATIONS. To install remaining components, reverse removal procedure. NEW SHIM THICKNESS TAB
