Hyundai Palisade: Cylinder Head Assembly / Valve clearance adjustment
| Valve Clearance Inspection
and Adjustment (MLA) |
| • |
Inspect and adjust the valve clearance with engine cold (engine
coolant temperature : 20°C (68°F)) and cylinder head installed
to the cylinder block.
|
|
| 1. |
Remove the cylinder head cover.
(Refer to Cylinder Head Assembly - "Cylinder Head Cover")
|
| 2. |
Set No.1 cylinder to TDC / compression.
| (1) |
Turn the crankshaft damper pulley clockwise and align its groove
with the timing mark "T" of the lower timing chain cover.
|
| (2) |
Check that the mark of the camshaft timing sprockets are in
straight line on the cylinder head surface as shown in the illustration.
If not, turn the crankshaft clockwise one revolution (360°).

|
| 3. |
Inspect the valve clearance.
| (1) |
With No.1 cylinder at TDC, inspect clearances only for the valves
shown below.

How to Measure :
| 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 replacement
adjusting tappet.
|
|
Valve clearance (Engine coolant temperature : 20°C [68°F])
[Specification]
Intake : 0.10 - 0.30 mm (0.0039 - 0.0118 in.)
Exhaust : 0.20 - 0.40 mm (0.0079 - 0.0157 in.)
|
|
| (2) |
Turn the crankshaft pulley clockwise one revolution (360°) and
align the groove with timing mark "T" of the lower timing chain
cover.
|
| (3) |
With the No.4 cylinder at TDC, inspect clearances only for the
valves shown in diagram below.
(Refer to procedure step 1.)

|
|
| 4. |
Adjust the intake and exhaust valve clearance.
| (1) |
Set the No.1 cylinder to the TDC/compression.
|
| (2) |
Remove the camshaft assembly.
(Refer to Cylinder Head Assembly - "CVVT & Camshaft")
|
| (4) |
Measure the thickness of the removed tappet using a micrometer.
|
| (5) |
Calculate the thickness of a new tappet so that the valve clearance
comes within the specified value.
|
T : Thickness of removed tappet
A : Measured valve clearance
N : Thickness of new tappet
Intake : N = T + [A - 0.20 mm (0.0079 in.)]
Exhaust : N = T + [A - 0.30 mm (0.0118 in.)]
|
|
| (6) |
Select a new tappet with a thickness as close as possible to
the calculated value.
|
• |
Shims are available in 41 size increments of
0.015 mm (0.0006 in.) from 3.00 mm (0.1181 in.)
to 3.60 mm (0.1417 in.).
|
|
|
| (7) |
Place a new tappet on the cylinder head.
|
• |
Apply engine oil around and on top of selected
tappet.
|
|
|
| (8) |
Install the intake and exhaust camshafts.
|
| (9) |
Install the bearing caps.
(Refer to Cylinder Head Assembly - "CVVT & Camshaft")
|
| (10) |
Install the timing chain.
(Refer to Timing System - "Timing Chain")
|
| (11) |
Make two turns on the crankshaft in the operating direction
(clockwise) and realign crankshaft sprocket and camshaft sprocket
timing marks.

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