INSPECT VALVE CLEARANCE Check only the valves indicated. Using a feeler gauge, measure the clearance between the valve lifter and 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.

Remove the plug from the timing chain cover. Using driver to hold the stopper plate of tensioner above the chain tentioner service hole. (f) Turn the exhaust camshaft a little clockwise. (g) Remove the driver from the chain tensioner service hole to lower the stopper plate, then insert the bar of 2 - 3 mm (0.08 - 0.12 in.). NOTICE: When the bar does not get inserted, turn the exhaust camshaft a little counterclockwise, then clockwise to insert it. Fix the bar with tape or others so that it does not be dropped off. (h) Hold the hexagonal portion of camshaft with a wrench, and loosen the bolt for camshaft timing sprocket. (i) Remove the 19 bolts, No. 1 and No. 2 camshaft bearing caps. (j) Remove the bolt and valve timing sprocket with the chain. (k) Hold the hexagonal portion of the camshaft with a wrench, and remove the bolt and valve timing controller assembly with the chain. NOTICE: Do not disassembled the valve timing controller assembly. (l) Remove the intake and exhaust camshaft assembly. HINT: When disconnect the timing chain from the camshaft timing sprocket, holding the timing chain.
(m)
Tie the timing chain with a string as shown in the illustration. NOTICE: Be careful not to drop anything inside the timing chain cover. Do not allow the chain to come into contact with water or dust. (n) Remove the valve lifters.

VALVE CLEARANCE
Determine the replacement valve lifter size according to these Formula or Charts: Using a micrometer, measure the thickness of the removed lifter. Calculate the thickness of a new lifter so the valve clearance comes within the specified value. T.......... Thickness of used lifter A......... Measured valve clearance N......... Thickness of new lifter Intake N = T + (A - 0.20 mm (0.008 in.)) Exhaust N = T + (A - 0.30 mm (0.012 in.)) Select a new lifter with a thickness as close as possible to the calculated values.
HINT: Lifter are available in 35 sizes in increments of 0.020 mm (0.0008 in.), from 5.060 mm (0.1992 in.) to 5.740 mm (0.2260 in.).
