Hyundai Palisade: Engine Mechanical System / Repair procedures
Compression Pressure Inspection |
• |
If the there is lack of power, excessive oil consumption or
poor fuel economy, measure the compression pressure.
|
|
1. |
Warm up engine until the normal operating temperature (80 - 95°C (176-203°F)).
|
2. |
Remove the air duct.
(Refer to Intake and Exhaust System - "Air Cleaner")
|
3. |
Remove the battery.
(Refer to Engine Electrical System - "Battery")
|
4. |
Remove the air cleaner assembly.
(Refer to Intake and Exhaust System - "Air Cleaner")
|
5. |
Remove the surge tank.
(Refer to Intake And Exhaust System - "Surge Tank")
|
6. |
Remove the ignition coils.
(Refer to Engine Electrical System - "Ignition Coil")
|
7. |
Remove the spark plugs.
(Refer to Engine Electrical System - "Spark Plug")
|
8. |
Check cylinder compression pressure.
(1) |
Insert a compression gauge into the spark plug hole.
|
(2) |
Fully open the throttle.
|
(3) |
Crank the engine over 7 times to measure compression pressure.
• |
Always use a fully charged battery to obtain
engine speed of 250 rpm or more.
|
|
|
(4) |
Repeat step 1) though 3) for each cylinder.
• |
This measurement must be done in as short a
time as possible.
|
|
Compression pressure :
1,373 kPa (14.0 kgf/cm², 199 psi) (250 - 400 rpm)
Minimum pressure :
1226 kPa (12.5 kgf/cm², 178 psi)
Difference between each cylinder :
98kPa (1.0kg/cm², 14psi) or less
|
|
(5) |
If the cylinder compression in 1 or more cylinders is low, pour
a small amount of engine oil into the cylinder through the spark
plug hole and repeat step 1) through 3) for cylinders with low
compression.
a. |
If adding oil helps the compression, it is likely that
the piston rings and/or cylinder bore are worn or damaged.
|
b. |
If pressure stays low, a valve may be sticking or seating
is improper, or there may be leakage past the gasket.
|
|
|
9. |
Reinstall the spark plugs.
|
10. |
Install the ignition coils and ignition connectors.
|
11. |
Install the surge tank.
(Refer to Intake And Exhaust System - "Surge Tank")
