Kia Carnival (2007 year). Instruction — part 410

(5) Remove the bearing caps.

(6) Measure the plastigage at its widest point.

Bearing oil clearance
Standard : 0.040 ~ 0.080mm (0.0016 ~ 0.0031in)

If the oil clearance is greater than maximum, replace the camshaft. If necessary, replace the bearing caps and
cylinder head as a set.

(7) Completely remove the plastigage.

(8) Remove the camshafts.

3. Inspect the camshaft end play.

(1) Install the camshafts.

(2) Using a dial indicator, measure the end play while moving the camshaft back and forth.

Camshaft end play
Standard : 0.08 ~ 0.17mm (0.0031 ~ 0.0067in)

If the end play is greater than maximum, replace the camshaft. If necessary, replace the bearing caps and
cylinder head as a set.

(3) Remove the camshafts.

Rockerarm and rockerarm shaft

1. Inspect the rockerarm and rockerarm shaft.

(1) Measure the inner diameter of the rocker arm, using a caliper gauge.

Rockerarm inner diameter
20.000~20.027mm (0.7874~0.7885in)

(2) Measure the inner diameter of the rocker arm, using a micro meter.

Rockerarm shaft outer diameter
19.959~19.980mm (0.7858~0.7866in)

Calculate the clearance between the rocker arm and the rocker arm shaft by the difference between the inner
and outer diameter of the rocker arm.

Rockerarm and rockerarm shaft clearance
0.020~0.068mm (0.0008~0.0027in)

If the clearance is out of the specification above, replace the rocker arm and rocker arm shaft.

HLA (HYDRAULIC LASH ADJUSTER)

Sieze the 'A' part of the HLA filled with engine oil. If it is moved when pushed the 'B' part by hand, replace it.

Problem

Possible cause

Action

Temporary noise when startinga
cold engine

Normal

This noise will disappear afterthe
oil in the engine reachesthe
normal pressure.

Continuous noise when theengine
is started after parkingmore than
48 hours.

Oil leakage of the high pressurechamber on
the HLA, allowingair to get in.

Noise will disappear within
15minutes when engine runs
at2,000~3,000 rpm.If it
doesn'tdisappear, refer to step 7
below.

Do not run engine at a speed
higher than 3,000 rpm, as this
may damage the HLA.

Continuous noise when theengine
is first started afterrebuilding
cylinder head.

Insufficient oil in cylinder head oil gallery.

Continuous noise when theengine
is started after excessively
cranking the engine by the starter
motor.

Oil leakage of the high-pressure chamber in
the HLA, allowing air to get in.
Insufficient oil in the HLA.

Continuous noise when the
engine is running after changing
the HLA.

Continuous noise during idleafter
high engine speed.

Engine oil level too high or too low.

Check oil level.
Drain or add oil as necessary.

Excessive amount of air in theoil at high
engine speed.

Check oil supply system

Noise continues for morethan 15
minutes.

Deteriorated oil.

Check oil quality.
If deteriorated, replace with
specified type.

Low oil pressure

Check oil pressure and oil
supplysystem of each part of
engine.

Faulty HLA.

Remove the cylinder head
coverand press HLA down by
hand.If it moves, replace the HLA.

Be careful with the hot HLAs.

REASSEMBLY

a. Thoroughly clean all parts to be assembled.
b. Before installing the parts, apply fresh engine oil to all sliding and rotating surface.
c. Replace oil seals with new ones.

1. Install the valves.

(1) Install the spring seats.

(2) Using the SST (09222 - 22001), push in a new oil seal.

Do not reuse old valve stem oil seals.
Incorrect installation of the seal could result in oil leakage past the valve guides.

(3) Install the valve, valve spring and spring retainer.

Place the valve springs so that the side coated with enamel faces toward the valve spring retainer and
then installs the retainer.

(4) Using the SST(0K993 120 004, 0K993 120 001), compress the spring and install the retainer locks. After

installing the valves, ensure that the retainer locks are correctly in place before releasing the valve spring
compressor.

(5) 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.

proper seating of the valve and retainer lock.
