INSPECTION

HINT

This check is used only to determine whether or not the idle CO/HC complies with regulations.

Scheme 14

Scheme 14: INSPECTION

Scheme 15

Scheme 15
  1. INITIAL CONDITIONS The engine is at normal operating temperature. Air cleaner is installed. All pipes and hoses of the air induction system are connected. All accessories are switched OFF. All vacuum lines are properly connected. HINT: All vacuum hoses should be properly connected. SFI system wiring connectors are fully plugged. Ignition timing is set correctly. Transmission is in neutral range. Tachometer and CO/HC meter are calibrated by hand.
  2. START ENGINE
  3. RACE ENGINE AT 2,500 RPM FOR APPROX. 180 SECONDS
  4. INSERT CO/HC METER TESTING PROBE AT LEAST 40 cm (1.3 ft) INTO TAILPIPE DURING IDLING
  5. IMMEDIATELY CHECK CO/HC CONCENTRATION AT IDLE AND/OR 2,500 RPM HINT: When performing the 2 mode (2,500 rpm and idle) test, follow the measurement order prescribed by the applicable local regulations.
  6. TROUBLESHOOTING HINT: If the CO/HC concentration does not comply with the regulations, perform troubleshooting in the order given below. See the table below for possible causes, and then inspect and correct the applicable causes if necessary.

HINT

If there is a lack of power, excessive oil consumption or poor fuel economy, measure the compression pressure.

Scheme 16

Scheme 16: INSPECTION
  1. WARM UP AND STOP ENGINE Allow the engine to warm up to the normal operating temperature.
  2. REMOVE SPARK PLUGS (See «REMOVAL & INSTALLATION - V6 & V8»(ref-151984) )
  3. CHECK CYLINDER COMPRESSION PRESSURE Insert a compression gauge into the spark plug hole. Fully open the throttle. While cranking the engine, measure the compression pressure. HINT: Always use a fully charged battery to obtain the engine speed at 250 rpm or more. Repeat steps (a) to (c) for each cylinder. NOTE: This measurement must be done as quickly as possible. Compression pressure: 1,324 kPa (13.5 kgf/cm 2 , 192 psi) or more Minimum pressure: 981 kPa (10.0 kgf/cm 2 , 142 psi) Difference between each cylinder: 98 kPa (1.0 kgf/cm 2 , 14 psi) or less If the cylinder compression in one or more cylinders is lower than the specification, pour a small amount of engine oil into the cylinder through the spark plug hole and repeat steps (a) to (c) for the cylinders. If adding oil helps the compression, chances are that the piston rings and/or cylinder bore are worn or damage. If the pressure stays low, a valve may be sticking or the seating is improper, or there may be leakage past the gasket.
  4. REINSTALL SPARK PLUGS (See «REMOVAL & INSTALLATION - V6 & V8»(ref-151984) )

HINT

  10. INSPECT VALVE CLEARANCE Check only the valves indicated. Using a feeler gauge, measure the clearance between the valve lifter and the camshaft. Record the out-of-specification valve clearance measurements. They will be used later to determine the required replacement adjusting shim. Valve clearance (Cold): Intake 0.15 - 0.25 mm (0.006 - 0.010 in.) Exhaust 0.25 - 0.35 mm (0.010 - 0.014 in.) Turn the crankshaft 1 revolution (360°) and align the mark as above (See procedure in step 9 ). Check only the valves indicated . Measure the valve clearance. (See procedure in step ( a )).
  11. ADJUST VALVE CLEARANCE Remove the timing belt (See «REMOVAL»(/toyota/land-cruiser/100-2002-2005/remont/mechanical/#engine-mechanical) ). Remove the camshafts (See «REMOVAL»(/toyota/land-cruiser/100-2002-2005/remont/mechanical/#engine-mechanical) ). Remove the valve lifter and adjusting shim. Determine the replacement adjusting shim size according to the following Formula and Charts: Using a micrometer, measure the thickness of the removed shim. Calculate the thickness of a new shim so that the valve clearance comes within the specified value. T..... Thickness of removed shim A..... Measured valve clearance N..... Thickness of new shim Intake: N = T + (A - 0.20 mm (0.008 in.)) Exhaust: N = T + (A - 0.30 mm (0.012 in.)) Select a new shim with the closest thickness as close as possible to the calculated value. HINT: Shims are available in 41 increments of 0.020 mm (0.0008 in.), from 2.00 mm (0.0787 in.) to 2.80 mm (0.1102 in.). Place a new adjusting shim on the valve. Place the valve lifter.

  1. INSPECT TIMING BELT NOTE: Do not bend, twist or turn the timing belt inside out. Do not allow the timing belt to contact with oil, water or steam. Do not utilize timing belt tension when installing or removing the mount bolt of the camshaft timing pulley. If there any defects as (Scheme 51) the illustrations, check these points: Premature parting Check for proper installation. Check the timing cover gasket for damage and proper installation. If the belt teeth are cracked or damaged, check if either camshaft is locked. If there is noticeable wear or cracks on the belt face, check if there are nicks on the side of the idler pulley lock and the water pump. Even if there is wear or damage on only one side of the belt, check the belt guide and the alignment of each pulley. If there is noticeable wear on the belt teeth, check timing cover for damage and for foreign materials on the pulley teeth. If necessary, replace the timing belt.
  2. INSPECT IDLER PULLEYS Visually check the seal portion of the idler pulley for oil leakage. If leakage is found, replace the idler pulley. Check that the idler pulley turns smoothly. If necessary, replace the idler pulley.
  3. INSPECT TIMING BELT TENSIONER Visually check the seal portion of the tensioner for oil leakage. NOTE: If there is only the faintest trace of oil on the seal on the push rod side, the tensioner is all right. If leakage is found, replace the tensioner. Hold the tensioner with both hands, and push the push rod strongly to check that it doesn't move. If the push rod moves, replace the tensioner. NOTE: Never hold the tensioner push rod facing downward. Measure the protrusion of the push rod from the housing end. Protrusion: 10.5 - 11.5 mm (0.413 - 0.453 in.) If the protrusion is not as specified, replace the tensioner. INSPECT WATER PUMP (See «INSPECTION»(/toyota/land-cruiser/100-2002-2005/remont/cooling-system-mechanical/#water-pump) )

  20. IF NECESSARY, REMOVE SEMI-CIRCULAR PLUGS AND CAMSHAFT HOUSING PLUGS
  21. REMOVE CAMSHAFTS NOTE: Since the thrust clearance of the camshaft is small, the camshaft must be kept level while it is being removed. Otherwise, excessive pressure is put on the cylinder head journal thrust, causing a burr on the journal and damage on the camshaft. To avoid this, follow the steps below. Check the crankshaft pulley position. Check that the timing mark of the crankshaft pulley is aligned with the centers of the crankshaft pulley bolt and the idler pulley bolt. NOTE: Having the crankshaft pulley at the wrong angle can cause the piston head and the valve head to come into contact with each other when removing the camshaft, causing damage on them. So always set the crankshaft pulley at the correct angle. Remove the RH camshafts. Move a service bolt of the sub-gear upward by turning the hexagon shaped port of the exhaust camshaft with a wrench. Secure the sub-gear to the main gear with a service bolt. Recommended service bolt: SERVICE BOLT IDENTIFICATION Bolt Attribute Specification Thread diameter 6 mm Thread pitch 1.0 mm Bolt length 16 - 20 mm NOTE: When removing the camshafts, make sure that the torsional spring force of the sub-gear is eliminated by the above operation. Set the timing mark (1 dot mark) of the camshaft main gear at approx. 10° angle by turning the hexagon wrench head portion of the exhaust camshaft with a wrench. Uniformly loosen and remove the 22 bearing cap bolts a little at a time for several times in the sequence (Scheme 100). Remove the oil feed pipe, 9 bearing caps, cam shaft timing oil control valve and camshafts. Remove the LH camshafts. Move a service bolt of the sub-gear upward by turning the hexagon shaped port of the exhaust camshaft with a wrench. Secure the sub-gear to the main gear with a service bolt. Recommended service bolt: SERVICE BOLT IDENTIFICATION Bolt Attribute Specification Thread diameter 6 mm Thread pitch 1.0 mm Bolt length 16 - 20 mm NOTE: When removing the camshaft, make sure that the torsional spring force of the sub-gear is eliminated by the above operation. Align the timing mark (2 dot marks) of the camshaft drive gear by turning the hexagon wrench head portion of the exhaust camshaft with a wrench. Evenly loosen and remove the 22 bearing cap bolts a little at a time for several times as in the sequence (Scheme 103). Remove the oil feed pipe, 9 bearing caps, and camshafts.

Remove the camshaft sub-gear. Remove the camshaft gear spring. NOTE: Arrange the camshaft sub-gears and gear spring (RH and LH sides). NOTE: Be careful not to damage the camshaft timing tube.
  23. REMOVE OIL SEAL FROM INTAKE CAMSHAFT
  24. REMOVE SPARK PLUGS
  25. REMOVE CYLINDER HEAD AND EXHAUST MANIFOLD ASSEMBLIES Uniformly loosen the 10 cylinder head bolts on one side of each cylinder head in a little at a time for several times as in the sequence (Scheme 108), then do the other side as shown. Remove the 20 cylinder head bolts and the plate washers. NOTE: Removing the bolts in incorrect order could cause a warp or cracks in the cylinder head. Do not drop the plate washer of the cylinder head bolt into A area in the illustration. It will fall down to the oil pan through the cylinder head and the cylinder block. Lift the cylinder head from the dowels on the cylinder block, and place the 2 cylinder heads on wooden blocks. NOTE: After lifting off the cylinder head, pry off the cylinder head and the cylinder block with a screwdriver. NOTE: Be careful not to damage the contact surfaces of the cylinder head and the cylinder block. The cylinder head should not be tilted so to secure the valve lifter. If the cylinder head is tilted, remove the valve lifter and check that the adjusting shim is set correctly.
  26. REMOVE RH EXHAUST MANIFOLD FROM CYLINDER HEAD Remove the 4 bolts and the heat insulator. Remove the 8 nuts, the exhaust manifold and the gasket.
  27. REMOVE LH EXHAUST MANIFOLD FROM CYLINDER HEAD Remove the 4 bolts and the heat insulator. Remove the 8 nuts, the exhaust manifold and the gasket.
