2007 KIA CARNIVAL lock

Check the combustion chamber, intake ports, exhaust ports and cylinder block surface for cracks. If cracked,
replace the cylinder head.
VALVE AND VALVE SPRING
1.Inspect valve stems and valve guides.
(1) Using a caliper gauge, measure the inside diameter of the valve guide.
Valve guide inside diameter
Intake / Exhaust : 6.000 ~ 6.015mm (2.2362 ~ 2.2368in.)
(2)Using a micrometer, measure the outer diameter of the valve stem.
Valve stem outer diameter
Intake : 5.585 ~ 5.980mm (0.2348 ~ 0.2354in.)
Exhaust : 5.950 ~ 5.595mm (0.2343 ~ 0.2348in.)
(3)Calculate the clearance between the valve guides and the stems by difference between the valve stem
measured diameter and the valve guide measured inside diameter.
Valve stem - to- guide clearance
[Standard]
Intake : 0.020 ~ 0.050mm (0.0008 ~ 0.0020in.)
Exhaust : 0.035 ~ 0.065mm (0.0014 ~ 0.0026in.)
[Limit]
Intake : 0.10mm (0.0039in.) or less
Exhaust : 0.13mm (0.0051in.) or less
2. Inspect valves.
(1) Check the valve face angle.
(2) Check that the surface of the valve for wear.
If the valve face is worn, replace the valve.
(3) Check the valve head margin thickness.

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.

REASSEMBLY
a.Thoroughly clean all parts to be assembled.
b. Before installing the parts, apply fresh engine oil to all sliding and rotating surfaces.
c. Replace oil seals with new ones.
1. Install valves.
(1) Using SST(09222- 22001), push in a new valve stem seal with applying engine oil.
a.Do not reuse old valve stem seals.
Incorrect installation of the seal could result in oil leakage past the valve guides.
b. Reassemble the valve stem seals
(2) After applying engine oil on the outer surface of each valve stem, insert the valve in the valve guide.
Install the valve, valve spring and spring retainer.
When installing valve springs, the side coated with enamel should face toward the valve spring retainer
(3) Using the SST(09222 - 3K000, 09222 - 3C300), compress the springs and install the retainer locks. After
installing the valves, ensure that the retainer locks are correctly in place before releasing the valve spring
compressor.

(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.

6.Check the connecting rod side clearance.
7. Check the connecting rod bearing oil clearance.
8. Remove the piston and connecting rod assemblies.
a.Keep the bearings the connecting rods and the caps together.
b. Arrange the piston and connecting rod assemblies in the correct order.
9. Remove the oil pump case.
10. Remove the oil seal case(A).
11.Check the crankshaft end play.
12. Remove the crankshaft bearing cap and check oil clearance.
Arrange the bearings and the bearing caps in order.
13. Lift the crankshaft(A) out of the block, being careful not to damage journals.

(6)If the plastigage measures too wide or too narrow, remove the upper half of the bearing, install a new,
complete bearing with the same color mark (select the color as shown in the next column), and recheck the
clearance.
Do not file, shim, or scrape the bearings or the caps to adjust clearance.
(7) If the plastigage shows the clearance is still incorrect, try the next larger or smaller bearing (the color listed
above or below that one), and check clearance again.
If the proper clearance cannot be obtained by using the appropriate larger or smaller bearings, replace the
crankshaft and start over.
If the marks are indecipherable because of an accumulation of dirt and dust, do not scrub them with a wire
brush or scraper. Clean them only with solvent or detergent.
Crankshaft bore mark location
Letters have been stamped on the block as a mark for the each size of the 4 main journal bores.
No.1 journal stamping mark starts from the front of the engine.
Use the size marks which are stamped on the block and the crankshaft for the journal bore inner diameter and
the journal outer diameter to choose the correct bearings.
