HINT: A warmed up engine should have an engine coolant temperature of over 80°C (176°F), an engine oil temperature of 60°C (140°F), and the engine speed should be stabilized. Disconnect the cable from the negative (-) battery terminal. Remove the air cleaner cap sub-assembly. Refer to «REMOVAL - Step 4»(/lexus/is-f/i-2007-2014/remont/testing-diagnostics/#engine-control-service-information) . Remove the battery. Remove the 8 spark plugs.

Disconnect the 2 injector connectors as shown in the illustration. Disconnect the 4 injector connectors as shown in the illustration. Insert a compression gauge into the spark plug hole. Install the battery. Connect the cable to the negative (-) battery terminal. Fully open the throttle valve. Depress and hold the brake pedal, and turn the engine switch on (IG). Then check the compression pressure. Standard compression pressure 1400 kPa (14.0 kgf/cm 2 , 203 psi) or more Minimum pressure 980 kPa (10.0 kgf/cm 2 , 142 psi) Pressure difference 100 kPa (1.0 kgf/cm 2 , 14.5 psi) or less NOTE: The measurement must be done as quickly as possible. HINT: Always use a fully charged battery to obtain engine speed of 250 rpm or more. If the cylinder compression is low in one or more cylinders, pour a small amount of engine oil into the cylinder with low compression through its spark plug hole. Then inspect the cylinder compression pressure again. HINT: If adding oil helps boost the compression, it is likely that the piston rings and/or cylinder bore are worn or damaged. If pressure stays low, a valve may be stuck or seated improperly, or there may be leakage in the gasket. Disconnect the cable from the negative (-) battery terminal. Remove the battery. Connect the 4 injector connectors as shown in the illustration. Connect the 2 injector connectors as shown in the illustration. Connect the throttle body connector. Install the 8 spark plugs.

HINT: If the timing marks are not positioned as shown in the illustration, rotate the crankshaft 360° to align the timing marks.
10. INSPECT VALVE CLEARANCE Using a feeler gauge, measure the clearance between the indicated valve rocker arms and camshafts. Standard Valve Clearance (Cold) Item Specified Condition Intake 0.12 to 0.18 mm (0.00472 to 0.00709 in.) Exhaust 0.22 to 0.28 mm (0.00866 to 0.0110 in.) HINT: On this engine, valve clearance is measured between the valve rocker arms and the camshaft lobes. The shims used to adjust the valve clearance are located on the top of the valve stems. The valve clearance shown in the Standard Valve Clearance table is the clearance as measured between the cam lobe and valve rocker arm. Record any out-of-specification valve clearance measurements. They will be used later to determine the required replacement valve adjusting shim. Turn the crankshaft 1 revolution (360°) to set the No. 6 cylinder to TDC compression. Using a feeler gauge, measure the clearance between the indicated valve rocker arms and camshafts. Standard Valve Clearance (Cold) Item Specified Condition Intake 0.12 to 0.18 mm (0.00472 to 0.00709 in.) Exhaust 0.22 to 0.28 mm (0.00866 to 0.0110 in.) HINT: On this engine, valve clearance is measured between the valve rocker arms and the camshaft lobes. The shims used to adjust the valve clearance are located on the top of the valve stems. The valve clearance shown in the Standard Valve Clearance table is the clearance as measured between the cam lobe and valve rocker arm. Record any out-of-specification valve clearance measurements. They will be used later to determine the required replacement valve adjusting shim.
11. ADJUST VALVE CLEARANCE Remove the timing chain cover sub-assembly. Refer to «REMOVAL»(/lexus/is-f/i-2007-2014/remont/lubrication-system/#lubrication-service-information) . Remove the camshaft. Refer to «REMOVAL»(/lexus/is-f/i-2007-2014/remont/mechanical/#engine-mechanical-service-information) . Raise the valve rocker arm above the shim being replaced, and remove the valve adjusting shim. NOTE: Be careful not to drop the adjusting shim into the cylinder head. To prevent damage, do not attempt to adjust valve clearance by tightening or loosening the valve rocker arm pivots. HINT: Arrange the removed parts in the correct order. Using a dial gauge, measure the thickness of the existing valve adjusting shim after removing it. HINT: Be careful not to measure at the valve adjusting shim center groove. Determine the replacement valve adjusting shim thickness according to the formula or charts below. Calculate the thickness of the replacement valve adjusting shim so that the valve clearance comes within the specified value. T2 Thickness of replacement shim T1 Thickness of existing shim A Measured valve clearance Valve clearance Intake T2 = T1 + (A - 0.15 mm (0.0059 in.)) x 1.8 Exhaust T2 = T1 + (A - 0.25 mm (0.0098 in.)) x 1.6 This example is provided only as a calculation example, based on the clearance adjustment of an intake valve. If non-metric units are being used, substitute those measurements for the values shown below. Step 1 - Determining the amount of excess clearance The specified clearance (0.15) is subtracted from the measured value (0.40), and the result is then multiplied by the rocker ratio compensation value (1.8). (Measured value - specification) x compensation value = amount of excess clearance (0.40 - 0.15) x 1.8 = 0.450 Step 2 - Using the existing valve adjusting shim to determine the required thickness of the replacement valve adjusting shim The amount of excess clearance (0.450) is added to the thickness of the existing valve adjusting shim (2.300). The resulting value is the ideal thickness of a replacement valve adjusting shim. Excess clearance + thickness of existing shim = thickness of ideal replacement shim 0.450 + 2.300 = 2.750 Step 3 - Select the valve adjusting shim closest to the thickness of the ideal replacement shim Compare the thickness of the available replacement valve adjusting shims to the ideal replacement shim and choose the shim that is the closest match. Closest replacement valve adjusting shim = 2.750 (Select a new No. 74 shim.) HINT: Select a replacement shim with a thickness as close to the calculated value as possible. Shims are available in 41 sizes in increments of 0.020 mm (0.0008 in.), from 2.000 mm (0.0787 in.) to 2.800 mm (0.1102 in.). To select a replacement valve adjusting shim, refer to the following Valve Adjusting Shim Selection Chart and New Shim Thickness tables. Intake valve clearance (Cold) 0.12 to 0.18 mm (0.00472 to 0.00709 in.) EXAMPLE: If the existing shim (installed shim) is 2.300 mm (0.0906 in.), and the measured clearance is 0.39 mm (0.0154 in.), then a new 2.740 mm (0.1079 in.)
