- Remove all of the ignition coils.
- Remove the cylinder head cover. CAUTION: Turn the crankshaft always clockwise.
- Turn the crankshaft clockwise, and align the timing mark on the exhaust camshaft sprocket against the upper face of the cylinder head as shown in the illustration. Therefore, No. 1 cylinder goes to the compression top dead center.
- Using a thickness gauge, measure the valve clearance with the arrow shown in the illustration. If deviated from the standard value, make note for the valve clearance. Standard value: Intake valve 0.20 ± 0.03 mm (0.008 ± 0.0012 inch) Exhaust valve 0.30 ± 0.03 mm (0.012 ± 0.0012 inch)
- Turn the crankshaft clockwise 360 degrees, and put the timing mark on the exhaust camshaft sprocket in position shown in the illustration. Therefore, No. 4 cylinder goes to the compression top dead center.
- Check the valve clearance with the arrow shown in the illustration. In the same procedure as 4.
- If the valve clearance is deviated from the standard value, remove the camshaft and the valve tappet. For the camshaft removal, refer to «REMOVAL AND INSTALLATION»(ref-593001-S02744032152014011300000) .
- Using a micrometer, measure the thickness of the removed valve tappet.
- Calculate the thickness of the newly installed valve tappet through the following equation. thickness of newly installed valve tappet thickness of removed valve tappet measured valve clearance Equation Intake valve: A = B + [C - 0.20 mm (0.008 inch)] Exhaust valve: A = B + [C - 0.30 mm (0.012 inch)] NOTE: The valve tappet ranges 3, 000 - 3, 690 mm (0.1181 - 0.1453 inch) and has 47 types per 0.015 mm (0.0006 inch). The thickness below a decimal point is stamped on the reverse side of the valve tappet.
- Install the valve tappet selected through the procedure 9, and put the camshaft in position. For the camshaft installation, refer to «REMOVAL AND INSTALLATION»(ref-593001-S02744032152014011300000) .
- After installing the timing chain, measure the valve clearance using the procedure 3 to 6. Confirm the clearance is within the standard value. CAUTION: Completely remove all the old FIPG, which might be remaining among the components.
- After completely removing the liquid gasket adhering on the timing chain case, cylinder block and cylinder head, degrease them with white gasoline. CAUTION: The cylinder head cover should be installed within 3 minutes of applying liquid gasket.
- Apply a 4 mm bead of liquid gasket as illustrated. Specified sealant: THREE BOND 1217G or equivalent
- Install the cylinder head cover and tighten the tightening bolts using the following procedures. Temporarily tighten to the following torque in order shown in the illustration. Tightening torque: 3.0 ± 1.0 N.m (27 ± 9 in-lb) Tighten to the specified torque in order shown in the illustration. Specified torque: 5.5 ± 0.5 N.m (49 ± 9 in-lb)
- Install the ignition coils.

- Remove the radiator condenser tank mounting bolt, and move the radiator condenser tank to a place where it does not interfere with the drive belt tension check (Refer to «RADIATOR»(ref-593034-S05530703302014011300000) . CAUTION: Check after turning the crankshaft clockwise one turn or more.
- Make sure that the indicator mark on the auto-tensioner is within the area marked with A in the illustration.
- If the mark is out of the area A, replace the drive belt (Refer to «CRANKSHAFT PULLEY»(ref-593001-S24979026432014011300000) . NOTE: The drive belt tension adjustment is not necessary as the auto-tensioner is adopted.
- Install the radiator condenser tank to the original position (Refer to «RADIATOR»(ref-593034-S05530703302014011300000) .
