Millenia V6-2255cc 2.3L DOHC (1995)
Valve Clearance: Testing and Inspection
1. Remove the intake manifold.
2. Remove the cylinder head cover.
3. Verify that the engine is in cold condition.
4. Measure the valve clearance.
a. Turn the crankshaft clockwise so that the No.1 piston is at Top Dead Center (TDC) of the compression stroke.
b. Measure the valve clearances at (A) in the image. With the engine cold, the standard clearances should read as follows:
^
Intake: 0.27-0.33 mm (0.011-0.012 inch).
^
Exhaust: 0.27-0.33 mm (0.011-0.012 inch).
c. If the valve clearance exceeds the standard, replace the adjustment shim.
d. Turn the crankshaft approx. 240° clockwise so that the No.3 piston is at TDC of the compression stroke.
e. Measure the valve clearances at (B) in the image. With the engine cold, the standard should read as follows:
^
Intake: 0.27-0.33 mm (0.011-0.012 inch).
^
Exhaust: 0.27-0.33 mm (0.011-0.012 inch).
f.
If the valve clearance exceeds the standard, replace the adjustment shim.
g. Turn the crankshaft approx. 240° clockwise so that the No.5 piston is at TDC of the compression stroke.
h. Measure the valve clearances at (C) in the image. With the engine cold, standard should read as follows:
^
Intake: 0.27-0.33 mm (0.011-0.012 inch).
^
Exhaust: 0.27-0.33 mm (0.011-0.012 inch).
i.
If the valve clearance exceeds the standard, replace the adjustment shim.
5. Install the cylinder head cover.
6. Install the intake manifold.
