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”.

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

Toyota 1ZZ-FE Engine Specifications

SPECIFICATION Table 1 lists the basic specifications of the 1ZZ-FE engine. Fig. 4 shows cross-sections of the engine and Fig. 5 shows the appearance of the engine and a comparison of dimensions with the previous engine. HIGH PERFORMANCE AND GOOD FUEL ECONOMY Fig. 6 shows the performance curve of the 1ZZ-FE engine. Compared with the previous engine, the specific fuel consumption has been greatly improved over the entire range. In addition, the engine’s maximum output and torque have been improved and, at the same time, a moderate torque curve is achieved by eliminating torque drops in the low-to-mid-speed range for easy-to-handle output characteristics Name 1ZZ-FE Type Water-cooled, gasoline, 4-cycle Displacement(cc) 1794 Arrangement & No. of Cylinders4-cylinder, In-line Type of Combustion Chamber Cross-flow, pentroof Valve mechanism 4-valve, DOHC, chain drive Fuel system Multi-point injection Bore × Stroke(mm) 79.0 × 915 Compression ratio 10.0:1 Valve head dia.

If at this point the vehicle does not run rough and/or stalls when the active test is performed, proceed with Repair Manual P1349 VVTi Fault Isolation Procedure (FIP). If the vehicle does stall and/or runs rough, this indicates the the VVTi control system is operating. Proceed to replace the VVTi actuator following the repair procedures listed on the Technical Information System (TIS): Engine Mechanical Section, Camshaft, Replacement The camshaft timing gear should come in the unlocked position from the factory. If it is difficult to install the camshaft timing gear, the lock pin may be engaged. To disengage the lock pin, apply and hold approximately 20 psi of air pressure at the oil feed hole located 90 degrees clockwise of the oval slot. (See Figure 1.) Once the pin has released, turn the interior assembly counterclockwise. (See black arrow in Figure 1.) B. Put the camshaft timing gear assembly and the camshaft together with the straight pin off the key groove. C. Turn the camshaft timing gear assembly (as shown in Figure 2) while pushing it lightly against the camshaft. Push further at the position where the pin fits into the groove. NOTE: Be sure not to turn the camshaft timing gear to the retard angle side (in the clockwise direction). D. Check that there is no clearance between the end of the camshaft and the camshaft timing gear. E. Tighten the camshaft bolt with the camshaft timing gear fixed. Torque: 54 Nm (551 kgfcm, 40 ftlbf) F. Check that the camshaft timing gear assembly can move to either side and is not locked
