2007 > 2.7L V6 GASOLINE >
Compression pressure inspection
If the there is lack of power, excessive oil consumption or poor fuel economy, measure the compression
pressure.
1. Warm up the engine until the normal operating temperature becoming 80~95°C(176~203°F).
2. Remove the surge tank.
3. Remove the ignition coil connectors(B) and ignition coils.
4.Using a 16mm plug wrench, remove the 6 spark plugs.
5. Check cylinder compression pressure.
(1) Insert a compression gauge into the spark plug hole.
(2) Open the throttle fully.
(3) With the fully - open throttle in cranking, measure the compression pressure.
Always use a fully charged battery to get the engine speed of 250 rpm or more.
Repeat steps 1) through 3) for each cylinder.
This measurement must be done in as short a time as possible.
Compression pressure: 1,176.79kPa (12.0kgf/cm², 170.68psi) - 200 ~ 250rpm
Minimum pressure: 1,029.69kPa (10.5kgf/cm², 149.34psi)
Difference between cylinders: 98.07kPa (1.0kgf/cm², 14.22psi)
(4) If the compression pressure in 1 or more cylinders is lower than the specification above, pour a small amount
of engine oil into the cylinder through the spark plug hole, repeat the steps (1) through (3) for the cylinder and
measure the pressure again.
a. If adding oil increases the pressure up, the piston rings or cylinder bores might be worn or damaged.
b. If the pressure doesn't increase, a valve may be sticking or seating may be improper, or there may be
leakage from the gasket.
6. Reinstall the spark plugs.
7. Install the ignition coils and connect ignition coil connectors.
8. Install the surge tank.
VALVE CLEARANCE INSPECTION AND ADJUSTMENT
Inspect and adjust the valve clearance when the engine is cold (Engine coolant temperature : 20°C
±5°C(59~77°F)) and cylinder head is installed on the cylinder block.

1.Remove the engine cover.
2. Remove air cleaner assembly.
3. Remove the surge tank.
4. Remove the cylinder head cover.
(1) Disconnect the ignition coil connector and remove the ignition coil.
(2) Remove the cylinder head cover.
5.Set the piston of the No.1 cylinder to TDC(Top Dead Center) position.
(1) Turn the crankshaft pulley clockwise and align its groove with the timing mark "T" of the timing chain cover.
(2) Check that the timing marks of the camshaft sprocket are in straight line on that of the cylinder head cover
surface as shwn in the illustration. It makes the piston of the No.1 cylinder position at TDC.
If not, turn the crankshaft one revolution clockwise.
6. Inspect the intake and the exhaust valve clearance.
(1) With the piston of the No.1 cylinder positioning at TDC, the valves which can be measured its clearance are as
shown below.
Measurement method.
a. Using a thickness gauge, measure the clearance between the tappet and the base circle of camshaft.
b. Record the out - of- specification valve clearance measurements. They will be used later to determine the
required adjusting tappet for replacement.

N : Thickness of new tappet
Intake : N = T + [A - 0.20mm(0.0079in.)]
Exhaust : N = T + [A - 0.30mm (0.0118in.)]
(8) Select a new tappet with a thickness as close as possible to the calculated value.
Tappets are available with 41different size increments of 0.015mm (0.0006in.) from 3.00mm (0.118in.) to
3.600mm (0.1417in.)
(9) Place a new tappet on the cylinder head.
Apply engine oil on the periphery surface of the selected tappet.
(10) Install the intake and exhaust camshafts.
(11) Install the bearing caps.
(12) Install the timing belt.
(13) Turn the crankshaft two revolutions in the operating direction(clockwise) and realign crankshaft sprocket and
camshaft sprocket timing marks(A).
(14) Recheck the valve clearance.
Specification (Engine coolant temperature: 20°C[68°F])
Intake : 0.17 ~ 0.23mm (0.0067 ~ 0.0090in.)
Exhaust : 0.27 ~ 0.33mm (0.0106 ~ 0.0129in.)

3.Replace the tensioner and the idler if grease is leaked from bearings.
TIMING BELT
1.Check the belt for oil or dust deposits.
Replace, if necessary.
Small deposits should be wiped away with a dry cloth or paper. Do not clean with solvent.
2. When the engine is overhauled or belt tension adjusted, check the belt carefully. If any of the following flaws are
evident, replace the belt.
a.Do not bend, twist or turn the timing belt inside out.
b. Do not allow the timing belt to come into contact with oil, water and steam.
3. Inspect the idler for easy and smooth rotation and check for play or noise.

The length of the bolt(B) is longer than that of the bolt(C).
11. Install the timing belt.(Refer to 'Timing system').
12. Check and adjust the valve clearance.
13. Install the cylinder head cover.
(1) Remove oil, dust or sealant on the upper surface of the cylinder before assembling cylinder head cover.
(2) Assemble the cylinder head cover in five minites after applying liquid gasket(LOCTITE 5900) on the camshaft
cap and packing part.
(3)Tighten the cylinder head cover bolts as following order(A).
Tightening torque
7.8~9.8Nm(0.8~1.0kgf.m, 5.8~7.2lb- ft)

If the end play is greater than the maximum, replace the camshaft. If necessary, replace the cylinder head.
(3) Remove the camshafts.
CVVT ASSEMBLY
1.Inspect CVVT assembly.
(1) Fix the CVVT assembly with a vice. Ensure that the cam lobe and journal is not damaged.
(2) Check that the CVVT assembly will not turn.
It should not be turned.
(3) Apply vinyl tape to the retard hole except the one(A) indicated by the arrow in the illustration.
(4)Wind tape around the tip of the air gun and apply air of approx. 150kpa(1.5kgf/cm², 21psi) to the port of the
camshaft.
(Perform this in order to release the lock pin for the maximum delay angle locking.)
When the oil splashes, wipe it off with a shop rag.
(5) After the lock pin released, the CVVT assembly can turned in advanced direction.
If the air applied is leaked much, the lock pin can not be released.
(6) Except the position where the lock pin meets at the maximum delay angle, let the CVVT assembly turn back
and forth and check the movable range and that there is no resistance to movement.
Standard: Movable smoothly in the range about 60°
(7) Turn the CVVT assembly with your hand in retard direction and lock it at the maximum delay angle position.

(4)Lightly tap the end of each valve stem two or three times with the wooden handle of a hammer to ensure
proper seating of the valve and retainer lock.
2. Install MLAs with engine oil applied on its surface.
Check that the MLA rotates smoothly by hand.
MLA should be reinstalled in its original position.
3. Install OCV(Oil Control Valve)(A).
Tightening torque
7.8 ~ 9.8Nm(0.8 ~ 1.0kgf.m, 5.8 ~ 7.2lb - ft)
a.To install OCV with gray colored connector into RH bank.
b. To install OCV with black colored connector into LH bank.

INSTALLATION
Installation is in the reverse order of removal.
Perform the following :a. Adjust the shift cable.
b. Refill the engine with engine oil.
c. Refill the transaxle with fluid.
d. Refill the radiator with engine coolant.
e. Bleed air from the cooling system with the heater valve open.
f. Clean the battery posts and cable terminals with sandpaper assemble them, then apply grease to prevent
corrosion.
g. Inspect for fuel leakage.
After assembling the fuel line, turn on the ignition switch (do not operate the starter) so that the fuel pump runs for
approximately two seconds and fuel line pressurizes.
Repeat this operation two or three times, then check for fuel leakage at any point in the fuel line.
