Kia Carnival (2009+). Instruction — part 101

A. $ Using a thickness gauge, measure the clearance between the tappet and the base circle of camshaft.

$ Record the out-of-specification valve clearance measurements. They will be used later to determine the
required replacement adjusting tappet.

Valve clearance
Specification
Engine coolant temperature : 20°C [68°F]
Limit
Intake : 0.10 ~ 0.30mm (0.0039 ~ 0.0118in.)
Exhaust : 0.20 ~ 0.40mm (0.0079 ~ 0.0157in.)

(2) Turn the crankshaft pulley one revolution (360°) and align the groove with timing mark "T" of the lower timing

chain cover.

Do not rotate engine counterclockwise

(3) Check only valves indicated as shown. [NO. 4 cylinder : TDC/compression]. Measure the valve clearance.

(Refer to procedure step1))

7. Adjust the intake and exhaust valve clearance.

(1) Set the No.1 cylinder to the TDC/compression.

(2) Remove the timing chain.

Before removing the timing chain, mark the RH/LH timing chain with an identification based on the location
of the sproket because the identification mark on the chain for TDC(Top Dead Center) can be erased.

(3) Remove the camshaft bearing caps(A).

(4) Remove the camshaft assembly(A).

(5) Remove MLAs.

(6) Measure the thickness of the removed tappet using a micrometer.

(7) Calculate the thickness of a new tappet so that the valve clearance comes within the specified value.

Valve clearance(Engine coolant temperature: 20°C[68°F])
T : Thickness of removed tappet
A : Measured valve clearance
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.

Shims are available in 41size 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.

Appling engine oil at the selected tappet on the periphery and top surface.

(10) Install the intake and exhaust camshaft.

(11) Install the bearing caps

(12) Install the timing chain.

(13) Turn the crankshaft two turns in the operating direction(clockwise) and realign crankshaft sprocket and

camshaft sprocket timing marks(A).

(14) Recheck the valve clearance.

Valve clearance (Engine coolant temperature: 20°C[68°F])
[Specification]
Intake : 0.17 ~ 0.23mm (0.0067 ~ 0.0090in.)
Exhaust : 0.27 ~ 0.33mm (0.0106 ~ 0.0129in.)
