Valve Adjustment DOHC 2.5 Liter Engine:
Continue the measurement procedure by rotating the crankshaft pulley clockwise until the right side camshaft sprockets are in the position shown in the figure below (approximately 4 o’clock position). In this position, the #2 exhaust valves and the #3 intake valves can be measured and/or adjusted if necessary.
Next, rotate the crankshaft pulley clockwise until the right side camshaft sprockets are in the position shown in the figure below. (approximately 8 o’clock position). In this position, the #2 intake valves and the #4 exhaust valves can be measured and/or adjusted if necessary.
Finally, rotate the crankshaft pulley clockwise until the right side camshaft sprockets are in the position shown in the figure below. (approximately 10 o’clock position). In this position, the #1 exhaust valves and the #4 intake valves can be measured and/or adjusted if necessary.
You may prefer to adjust the valves as you go, or measure them all before returning to adjust those valves that require adjustment. If a valve requires adjustment, make sure the camshaft sprockets are in the proper position before attempting to depress the valve or remove a shim. This will prevent any unintentional valve interference problems.
